Description

  The present invention relates to a technique for controlling power supply during a power failure.

  In recent years, the importance of business continuity planning (hereinafter referred to as BCP) has increased in companies, and there has been a high demand from tenants moving into tenant buildings, and BCP countermeasures have been formulated for newly built buildings from the initial planning stage. In addition, ministries and local governments have issued subsidies for BCP countermeasures and guidelines for formulation, mainly for accepting people who have difficulty returning home in times of disaster. The recent BCP formulation and countermeasures were that less than 100,000 people were temporarily able to accept public and private facilities among the 5.1 million people who were unable to return home in the Tokyo metropolitan area due to the Great East Japan Earthquake. This is due to the impact of the planned power outage on corporate business plans.

  Currently, there are almost no vacant lots in the city center, so there are currently no BCP countermeasure buildings increasing rapidly, and BCP countermeasure renovation work in existing buildings has problems in construction and construction period. There is a situation where measures are not progressing.

  By the way, installation of private power generation equipment such as security power, emergency power, or standby power that can supply power in the event of a commercial power outage or a fire with a commercial power outage is required. It is required by law and electrical equipment technical standards, etc., and the power supply capacity of the emergency power source that can supply power to fire fighting equipment etc. is determined. Calculation of power supply capacity mainly includes loads required for fire-fighting facilities such as fire-fighting smoke removal equipment, sprinkler pumps and indoor fire hydrants (hereinafter referred to as “disaster prevention load”), emergency elevators and emergency lighting. It is calculated on the basis of the power used by the load necessary for the above (hereinafter referred to as “security load”). The power supply for safety is defined in the electrical equipment technical standards, and when the supply of commercial power from the power company is interrupted, the power supply for safety is used to maintain the functions of the electrical equipment in the customer. It is. It is not a power source used for evacuation and fire fighting activities, but a power source that is positioned for business continuity and security purposes. The emergency power supply is an “emergency power supply” that is defined in the Fire Service Act and is used when the power supply to the fire-fighting equipment is cut off. This equipment is connected to a fire hydrant, sprinkler, fire-fighting / smoke facility, etc., and supplies power so that the fire-fighting equipment can operate properly even if the commercial power supply is cut off. According to the Fire Service Act, the time that must be supplied to each fire fighting facility is determined. Specifically, it is determined that it can be continuously operated at a rated load for 60 minutes or more, that the fuel oil has a capacity of 2 hours or more, and that a voltage is established within 40 seconds. The standby power source is a “standby power source” defined in the Building Standard Law and used as a power source for emergency lighting, smoke exhaust facilities, and the like. As with emergency power supplies for fire-fighting facilities, even if commercial power is cut off, emergency lighting is planned to operate for a certain period of time. These private power generation facilities such as security power, emergency power, or standby power are hereinafter referred to as self power.

  With respect to these problems, Patent Document 1 discloses a technique capable of continuing power supply to a load by a self-power supply even when a commercial power supply fails due to a single power line. According to this literature, it classifies into the load group which may cut standby electric power, and the load group which should not cut standby electric power. And for the load group which may cut standby power, the power from the integrated system trunk line is branched via the normal distribution board and the extended distribution board. Here, the normal distribution board is composed of a main breaker connected to the system main line side and a plurality of branch breakers connected to the load side. The extension distribution board is composed of a plurality of remote control breakers. The remote control breaker can disconnect the line remotely in accordance with an external controller command. The external controller determines the number of remote control breakers to be cut off or the number thereof according to the situation by automatic or manual operation. Here, the status refers to the presence or absence of a power failure of the commercial power supply, the remaining amount of fuel of the self-power supply, the power consumption of the load, and the like. According to this document, in the event of a power failure of the commercial power supply, there is a high need for power supply instead of wastefully supplying power to a load that has a low need for power supply in a single system The self-power supply can be continuously supplied to the load. Furthermore, even when the commercial power supply is not out of power, the power supply to the load in the standby state can be cut off, so that energy saving and cost saving can be achieved by cutting off the standby power.

  As another conventional system, for example, a system that supplies power to facilities that require power by switching power supply lines by a combination of detection of power failure by a power failure detector and presence / absence of fire detection by a fire detector (for example, Patent Document 2), a system (for example, Patent Document 3) that supplies power by switching the power line with the remaining fuel of the emergency generator, and the like have been proposed.

  However, the cost of augmenting the self-power supply for emergency power supply capacity is high. Even if the self-power supply has sufficient power supply capacity in an emergency, the power supply capacity and the load to which power should be supplied vary depending on the state of the commercial power supply, the self-power supply, the fire, etc. Therefore, it is difficult to appropriately distribute power to a plurality of loads in a building.

  In order to solve the above problems, a power supply system according to one embodiment of the present invention includes a plurality of distribution boards connected to a commercial power supply and another power supply via a circuit breaker and a power line, and the plurality of distribution boards. And a control device connected to the panel via a communication line. Each of the plurality of distribution boards is between a specific current sensor that is a current sensor that outputs a measurement value obtained by measuring a current flowing from the power line to a specific load, and between the power line and the specific load. A specific remote control breaker which is a remote control breaker provided; and a control unit connected to the specific current sensor and the specific remote control breaker via a signal line. The control device includes fire occurrence information indicating whether or not a fire has occurred, power failure occurrence information indicating whether or not a commercial power failure has occurred, and self-power supply information indicating a remaining energy level of the self-power supply. And determining operations of the plurality of distribution boards based on state information including the fire occurrence information, the power failure occurrence information, and the self-power supply information, and operating instructions indicating the determined operations as described above. The control unit of the specific distribution board in the plurality of distribution boards determines a threshold value for the measured value based on the operation instruction, and inputs the specific remote operation breaker. Alternatively, controlling the shut-off state, the control unit of the specific distribution board determines whether or not the measurement value exceeds the threshold value, and if it is determined that the measurement value exceeds the threshold value, the specific remote operation Control breaker to shut off That.

  Appropriately and variably distributes the power from the commercial power supply and the self-power supply to multiple loads in the building by setting the remote control breaker and threshold according to the state of the fire, the commercial power supply, and the self-power supply can do.

  Hereinafter, an outline of an embodiment of the present invention will be described.

  For emergency power sources defined by the Fire Service Law, the fire service law stipulates that the time from the detection of a commercial power failure until the voltage is established is within 40 seconds. It is not always a blackout due to fire. In this case, the power supplied from the emergency power supply is supplied to the security load, and the power supply capacity for the disaster prevention load is left as surplus. If this surplus power (hereinafter, surplus power) is effectively used, power can be supplied to some important equipment such as servers.

Normally, when a BCP measure is taken for a building, it is necessary to install or reinforce the self-power supply facility, and install or renovate the power line. The reason why the BCP countermeasure does not advance is mainly the cost, construction period, and installation space. Specific examples are as follows.
・ The cost of self-power supply equipment is high. Especially in existing buildings, there is no space for installing or adding self-power supply equipment.
・ Reinforcement of the self-power supply facilities will require the building floors to be increased and the walls to be renovated for soundproofing due to the increased equipment weight. In addition, the cost of incidental work such as securing a flue for releasing smoke to the outside of the building and installing a self-powered cooling system is high. The same applies to the enhancement of incidental facilities such as fuel tanks.
・ In existing buildings, office workers are working during the daytime on weekdays, so the construction period will be longer due to mainly nighttime work on holidays. Since work costs during holidays and nights are generally increased, it is necessary to shorten the construction period as much as possible.
-It is necessary to renovate or add a new line to the existing line that supplies power from the existing power supply.

Since the surplus power of the self-power supply has a usable upper limit value within the range of the disaster prevention load, there is a problem that it is necessary to limit the power usage of the load facility that uses the surplus power. Further, in some buildings such as office buildings, it is necessary to cope with power supply control from a self-power supply to a plurality of users and to concentrate the power supply range in the use space. Specific examples of the problem include the following.
-If the surplus power of the disaster prevention load set at the time of the above capacity calculation is exceeded, the self-power supply will stop urgently.
-When using the above surplus power or shutting off, the self-power supply will stop urgently due to inrush current.
-Control to supply the above surplus power only to important devices such as servers, and limit the power used.
・ If a fire occurs while using the above surplus power, the surplus power must be stopped and a disaster prevention load must be established.
-In order to supply power to fire fighting facilities as stipulated in the Fire Service Act for more than 2 hours, the remaining time that the self-power supply can be operated must be judged, and the use of surplus power must be stopped based on a threshold value.
・ The power supply capacity of the entire building can be controlled in order to supply the above surplus power to multiple users in the building or to concentrate power supply in some spaces such as the disaster response headquarters of each company. It is necessary to construct a system that makes the power supply capacity for each space variable.

  Since the power supply system proposed in Patent Document 1 cannot be controlled at the time of fire detection, it is not appropriate to use the emergency power disaster prevention load as surplus power. In addition, this system remotely cuts off the power supply to the load at the time of power failure or power saving in units of branch breakers of the existing distribution board. In other words, the control unit installed for each distribution board controls on / off of the remote control breaker installed for each branch breaker. Therefore, when there are a plurality of existing distribution boards, a control unit installed for each of the plurality of distribution boards and a control unit for centrally controlling the plurality of control units are necessary. Furthermore, a considerable number of remote control breakers are required. The number of remote control breakers is not so large for ordinary households and small consumers, but for large consumers such as office buildings, factories and hospitals, the number of distribution boards ranges from tens to hundreds. There are usually several tens of branch breakers in each distribution board. Therefore, as a whole, the number of remote control breakers on the separately installed distribution board side becomes enormous, and the remote control breaker itself is larger than the branch breaker, so that the installation space becomes large.

  For example, in the Fire Service Act, an emergency generator must have fuel that can be operated for more than two hours. The uninterruptible power system utilizing the emergency generator proposed in Patent Document 2 automatically stops the load depending on the remaining fuel threshold when the remaining operating time is 2 hours, or the fuel Since there is no control to stop the load manually by checking the remaining amount by some method, it is not appropriate to use the disaster prevention load of the emergency generator as surplus power. In addition, the power supply capacity of the entire building cannot be controlled in order to supply power to multiple users in the building or to concentrate power supply in some spaces such as the disaster response headquarters of each company, or The power supply capacity for each space cannot be made variable.

  The self-sustained operation system utilizing the power storage / emergency power generator proposed in Patent Document 3 has sufficient power supply equipment for the general load and the first load, and supplies power to the first load. It is a premise to install a dedicated line that cannot solve the problems of cost, construction period, and installation space.

  On the other hand, the power supply system of the present embodiment supplies power to a general load and a preset load (hereinafter referred to as a BCP load) when power from the commercial power source is obtained, and a fire occurs when the commercial power source fails. The power for disaster prevention load of the self-power supply can be limitedly supplied to the BCP load under conditions such as not occurring. Furthermore, the power supply system can reduce the cost, construction period, and installation space, and can take measures against the BCP of the building by simplifying the reinforcement work of the self-power supply device and the housing and simplifying the circuit work. Also, assuming that there are multiple users in the building, overall power supply to the BCP load of multiple users is controlled, and the power supply capacity for each user and the concentration and averaging of the power supply space Is made variable.

  The building has a commercial power supply, a self-power supply device such as an emergency generator and a storage battery, and a service line connected to a general load, and an emergency line connected to a safety load and a disaster prevention load. Office buildings, factories and hospitals. The power supply system according to this embodiment supplies power from a self-power supply in the event of an emergency such as a power failure, and integrates the main line by installing multiple circuit breakers on the emergency line and the service line. It has a function of establishing a power supply line to a general load.

  When using surplus power, it is necessary to determine whether the surplus power can be used or not while determining whether it is an emergency or a fire has not occurred. Receive status signals such as power outage detection signal, fire occurrence signal, self power supply status from the detector or the central monitoring device or equipment control panel of the monitoring system provided in the building for building management, It has a function of judging by logical operation from the combination of each state signal.

  When it is determined from the logical operation result that the surplus power can be used, the centralized management control device opens and closes the plurality of circuit breakers described above, and selects a suitable mode from a plurality of preset modes. The function of outputting the signal of the selected mode to the control unit that controls the distribution board is provided. Further, the central management control device can be connected to the terminal device, display information and warnings of the entire system on the terminal device, and can input set numerical values.

  The control unit controls the circuit of the distribution board that supplies power from the service line to the general load. In addition to the control unit, the distribution board includes a current sensor, a plurality of remote control breakers (remote breaker, remote operation breaker), and a branch circuit that distributes power to a general load and a BCP load. The distribution board may further include a watt-hour meter connected to the communication network. This watt-hour meter is connected to a system such as xEMS (x-Energy Management System: x indicates Building, Factory, Cluster, Community, etc.), MDMS (Meter Data Management System), etc. via a communication network. It is a sensor that measures the amount of current and power supplied to the panel.

  The control unit is connected to the current sensor, has a function of constantly measuring the current in the distribution board, and has a function of opening and closing the remote control breaker. Further, the control unit has a function of receiving and storing an RB set value table indicating an open / close set value and a cut-off current set value for each mode from the central management control device. The mode indicates one of a plurality of values such as a normal mode, a BCP compatible mode, a cutoff mode, a maintenance mode, and a manual mode. An open / close set value and a cut-off current set value are registered for each mode. The open / close set value and the cut-off current set value can be changed according to the needs of each user by a terminal device connected to the central management control device.

  The control unit has a function of opening the remote control breaker to cut off the circuit when the current in the distribution board exceeds the cut-off current set value in the RB set value table. It has a function of limiting the power demand of the distribution board by the opening / closing operation of the remote control breaker arranged in each of the circuit supplying power to the general load and the circuit supplying power to the BCP load in the distribution board.

  For example, if the mode in which the central management control unit instructs the control unit is the BCP mode, the distribution board supplies power only to the BCP load. When the operation time reaches the time limit, the distribution board cuts off all of the general load and BCP load so as not to use surplus power. Furthermore, the centralized management control device has a function of setting an open / close setting value and a cutoff current setting value in each mode for each of a plurality of control units.

  The centralized management control device has a function of changing the timing of outputting a mode signal to each control unit. If the central control unit outputs a mode signal to start power supply to all control units at the same time, power will be supplied to all distribution boards at the same time. There is a case. Also, if the centralized control unit outputs a mode signal that stops power supply to all control units at the same time, an unmaintained self-power supply will stop urgently due to overrun, or dozens of remote control breakers Since a considerable amount of power is instantaneously used when the power is cut off, there is a phenomenon in which the current increases rapidly and then decreases rapidly. Therefore, a large load may be applied to the UPS that supplies power to the remote control breaker. To prevent these effects, it has a function to select the priority and order of outputting the mode signal to each control unit, and the output time interval (output time) that is the output time interval is set to an arbitrary time And has a function of outputting to all control units within an arbitrary end time. This function works when a mode signal is output to each control unit.

  The central management control device has a function of constantly monitoring a state signal of the remaining amount of fuel of the self-power supply or a state signal of the storage amount of the storage battery and calculating the remaining operation time of the self-power supply. Furthermore, when the remaining operating time reaches a preset remaining operating time threshold, the centralized management control device has a function of stopping the power supply from the self-power supply and shutting off the remote control breakers of all distribution boards. This is because the time for supplying power to the disaster prevention load is determined by the Fire Service Act, etc., so that the amount of fuel and the amount of electricity stored are left.

  The distribution board may be composed of a plurality of panels such as a main panel that receives power from the power line, a branch panel that supplies power to a circuit such as an outlet, and a control panel that controls the distribution panel. As a result, the distribution board can be installed separately or integrally.

  Each of the plurality of distribution boards in the building is controlled by the mode, the open / close setting value, and the cutoff current setting value. For example, in the BCP mode, the remote control breaker arranged in the general load supply circuit connected to the general load is cut off, and the cutoff current setting value of the remote control breaker arranged in the BCP load supply circuit connected to the BCP load is set to 10 amperes. The general load circuit is cut off and only the BCP load can use power up to 10 amps. The centralized control unit can calculate the maximum power consumption from the sum of the cut-off current settings for each BCP mode registered and set in the centralized control unit, so it is possible to set the BCP load according to the surplus power of the self-power supply. Thus, the power demand in the BCP mode can be limited. As a result, it is possible to reduce the influence of the power demand in the BCP mode exceeding the power supply capacity and urgently stopping the self power supply, and to use the power supply capacity for the disaster prevention load as surplus power.

  When the centralized control device outputs the mode signal to a plurality of control units, the output timing can be adjusted, so that the influence of the inrush current on the self-power supply can be reduced compared to when the mode signal is output simultaneously.

  Since the centralized management controller can output a mode signal to the control unit according to the priority set in advance for each distribution board, power demand can be obtained from the distribution board with lower priority according to conditions such as the operating time of the self-power supply. It can reduce and extend the operation time of the self-power supply.

  Since surplus power is supplied to the load from the service line and the circuit in the distribution board, a dedicated line for self-power supply, which is necessary in the past, becomes unnecessary, and the number of dedicated distribution boards installed is reduced. Reduction of installation space and materials, and construction period.

  By using surplus power, it is not necessary to reinforce the self-power supply or to add to the building, and the existing self-power supply can be used. For example, the self-power supply does not require a large self-power supply or transformer that exceeds the planned power supply capacity. Thereby, the installation space and members are reduced, and the construction period is reduced.

  If power is supplied from the BCP load circuit on the distribution board to BCP loads such as servers and outlets in the office space, the power from the self-power supply to the office space in the event of a power failure such as during a disaster Supply will be possible, and it will also be possible to handle people who have difficulty returning home.

  The centralized management control device may shut off the remote control breaker that leads to a load in a preset standby power state during a preset time period regardless of whether or not a commercial power supply is interrupted. As a result, it is possible to cut the standby power of loads such as air conditioning equipment, OA (Office Automation) equipment, production equipment, etc. that are not in operation at night or on holidays, thus saving energy.

  The power supply system of the present embodiment can construct a line in which a service line and an emergency line are system-linked by installing a system linkage protection device, and can supply power to the entire load. As a result, when the commercial power supply is not interrupted and there is no fire in the building, centralized management is performed when the total power used by the load is likely to exceed the contracted power based on the measured value from the current sensor. The control device can start the self-power supply or cut off the unnecessary general load to cut the peak. For example, the centralized management control apparatus can reduce the power consumption by acquiring information indicating the power consumption of the commercial power supply and starting the self power supply when the power consumption exceeds a predetermined power consumption threshold. . The power usage threshold is, for example, a value obtained by subtracting a predetermined margin from contract power.

  In general, the power supplied from the distribution board to the load is 50 amperes or 75 at the sub-breakers (distribution circuit breaker, Molded Case Circuit Breaker, branch breaker, manual breaker) of each branched wiring in the distribution board. It is determined by a fixed ampere trip such as ampere or 100 ampere. Therefore, when the power supply system of the present embodiment is not used, the power from the distribution board to the load is distributed by manually controlling the sub breaker. Also, the power distribution cannot be controlled in units smaller than the ampere trip of the sub breaker. In the present embodiment, an arbitrary ampere trip can be set by using a current sensor and a remote control breaker. Thereby, it can supply to a worker without leaving the power supply capacity of a commercial power supply and a self-power supply.

  The central management control device cuts off the power supply to loads other than the disaster prevention load and the security load when a fire is generated in the building using the self-power supply. Thereby, electric power can be supplied to disaster prevention load and security load such as fire fighting equipment in preference to general load and BCP load.

  The centralized management control device constantly calculates the remaining operation time of the self-power supply, and performs control to stop the power supply to the BCP load if the calculation result is equal to or less than a preset remaining operation time threshold. As a result, it is possible to maintain the power supply time to the disaster prevention load stipulated by the Fire Service Act. Since the central management control device can grasp the time for stopping the power supply to the BCP load by this calculation, for example, the remaining operating time threshold is set higher than the limit, and from the speaker before the stop (for example, 10 minutes before the limit). An alarm sound may be notified. As a result, the office worker can terminate the power supply of an important device such as a server in a normal process.

  The distribution board may be divided into a plurality of parts. Thereby, it is possible to carry in and install even in a place where the carry-in route that is often found in existing buildings is narrow or where the installation space is narrow.

  When there is an existing distribution board, the distribution board may be installed close to the existing distribution board. As a result, the repair work on the existing distribution board is completed in a short time, so even if the time during which the entire building can be cut off is limited to about one day per year, all of the distribution boards in the building will be repaired. Construction can be completed within a limited time.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 shows a functional configuration of a power supply system according to an embodiment of the present invention.

  In the present embodiment, a power supply system applied to an office building will be described, but this power system can also be applied to distribution facilities, factories, hospitals, and the like. The power supply system includes a centralized management control device 10, a plurality of distribution boards PB1, PB2,... PBn (n is an integer), a terminal device 111, a speaker 112, and circuit breakers CB1, CB2,. Integer) and UPS (Uninterruptible Power Supply) 115. Here, elements are distinguished by numerals attached to alphabets of symbols, but numerals may be omitted when it is not necessary to distinguish elements.

  The central management control apparatus 10 has a monitoring process 101, a logical operation process 102, and a control output process 103 as functions. The central management control device 10 is, for example, a computer, and includes a memory 121, a CPU (Central Processing Unit) 122, and a communication interface (I / F) 123, as shown in FIG. The memory stores programs and data. The CPU functions as a monitoring process 101, a logical operation process 102, and a control output process 103 in accordance with a program stored in the memory.

  Distribution board PBn includes a control unit CUn, a current transformer CTn, a meter Mn, and remote control breakers RBn1, RBn2,... RBnm (n and m are integers). The number of remote control breakers RB included in the distribution board PB may be one.

  The terminal device 111 is installed in a disaster prevention center in a building. The terminal device 111 is a computer, for example, and includes a memory, a CPU, a communication interface, an input device, and a display device. The memory stores programs and data. The CPU executes an input / output function in accordance with a program stored in the memory. The input device receives input from the administrator. The display device displays information from the central management control device 10. Instead of the terminal device 111, an input device and a display device connected to the central management control device 10 may be used.

  The speaker 112 is connected to the terminal device 111 and generates an alarm sound via the terminal device 111 in response to an instruction from the central management control device 10.

  The UPS 115 is installed in a disaster prevention center or the like in a building, and supplies power to the central management control device 10, the terminal device 111, the control unit CU, and the remote control breaker RB.

  The central management control device 10 is installed in a disaster prevention center or the like in a building, and can receive a status signal of a device related to the present system via a communication network and perform a status signal monitoring process 101. When a problem occurs in the result of the monitoring process 101, the central management control device 10 generates an alarm sound on the speaker 112 and displays an alarm on the terminal device 111. The terminal device 111 has a role as a user interface for monitoring status display, setting value input, current mode display, and the like of the central management control device 10, and a role of storing data.

  The monitoring process 101 uses the database area 14. The signals targeted for the monitoring process 101 are the status signal 11 of each detector output from a power failure detector of a commercial power source, a fire alarm panel of a building, and the control panel of a self-power source 54 such as an emergency generator or a storage battery. And the status signal 12 of each facility output from the circuit breaker and the status signal 13 of the distribution board PB output from the control unit CU arranged in the distribution board PB, and the like are stored in the database area 14. The database area 14 includes, for example, commercial power failure information, building fire information, self-power supply 54 voltage establishment information, commercial power recovery information, fire recovery information, commercial power and supply power value of the self-power 54 as status information. , Current value, electric energy, fuel amount of the self-power supply 54, RB open / close state of each remote control breaker RB, CB open / close state of each circuit breaker CB, storage amount of the self-power supply 54, and the like.

  The logical operation processing 102 performs logical operation on each status signal registered in the database area 14. The logical operation processing 102 always performs the mode determination 15 based on the combination of the state signals. When the mode is changed from the result of the mode determination 15, the logical operation processing 102 performs the open / close determination 16 of the circuit breaker CB according to the mode, and the circuit breakers CB 1, CB 2, CB 3,. The CBn CB opening / closing signal 17 is output, the circuit breaker CB is opened / closed according to the mode, and the power line can be switched. Further, the logical operation processing 102 performs the interlock 36 depending on conditions such as the occurrence of a fire.

  The control output processing 103 is based on the output destination priority processing 18 for the plurality of control units CU in the plurality of distribution boards PB and the output order processing 19 of the control unit CU in the logical operation processing 102. A mode signal output 20 indicating the mode is performed. At this time, the control output process 103 sequentially outputs a mode signal to a plurality of control units CU at a timing shifted by a preset interval, and completes output to all the control units CU within a preset end time. By performing the delay output 21, the inrush current to the power source can be reduced.

  The control unit CU has a storage area such as a memory. In the storage area, the RB setting value table 22 set and registered in the central management control apparatus 10 from the terminal device 111 is output from the central management control apparatus 10 and registered. In the RB set value table 22, an open / close set value for determining the open / close operation of the remote control breaker RB connected to the control unit CU and a cut-off current set value for determining a current for cutting off the remote control breaker RB are set and registered for each mode. Is done.

  The control unit CUn refers to the RB set value table 22 by referring to the input 23 of the mode signal from the centralized management control device 10, and the cut-off current set values of the remote control breakers RBn1, RBn2,... RBnm connected to the control unit CUn. , And an open / close determination 25 is performed according to the open / close setting value, and an open / close signal 26 of the remote control breakers RBn1, RBn2,... RBnm is output as a delay 27 to perform an open / close operation 28 of each remote control breaker RB according to the mode. Thus, the circuit in the distribution board PB can be controlled to open and close.

  The control unit CU is connected to a meter M housed in the distribution board PB via a network in order to measure the current value 29 in the distribution board PB and measure the electric energy 30. The table reference 31 for determining whether 29 exceeds the breaking current setting value registered in the RB setting value table 22 is always performed. The meter M is connected to the current transformer CT, and converts the current detected by the current transformer CT into a measured value. For example, when the electric wire is a three-phase alternating current, the current transformer CT includes a three-phase current transformer, and the meter M calculates a current from the output of the three-phase current transformer. Hereinafter, the current transformer CT and the meter M are collectively referred to as a current sensor. Here, when the current value 29 exceeds the breaking current set value, the control unit CU performs an RB opening / closing determination 25, outputs an RB opening signal 26, opens the remote control breaker RB 28, and shuts off the circuit. Can do.

  As a result, it is possible to control the power line centering on the centralized management control device 10 and the distribution board PB.

  The self-power supply 54 has a predetermined time for supplying power to the disaster prevention load according to the Fire Service Act. For this reason, the central management control device 10 constantly monitors the state signal of the remaining amount of fuel of the own power source 54 or the state signal of the storage amount of the storage battery, and calculates the remaining operation time 32 of the own power source 54. When the result of the logical operation satisfies a preset condition, all the remote control breakers RB of all the distribution boards PB are shut off in order to stop the power supply from the self power supply 54 to the distribution board PB. A mode signal is output to the control unit CU to cut off the power supply to the general load and the BCP load. For example, the centralized management control device 10 receives the accumulated power amount, the accumulated operation time, the oil level signal, the remaining amount of fuel, etc. of the self-power supply 54 and calculates the remaining operation time based on the received information. Instead of the remaining operating time, the remaining amount of energy of the self power supply 54 may be used. For example, the centralized management control device 10 acquires information indicating the remaining operation time, and displays a warning on the terminal device 111 and shuts off the remote control breaker RB when the remaining operation time is less than or equal to a preset time threshold value. A mode signal for controlling the state is transmitted to a plurality of distribution boards PB.

  The self-power supply 54 may supply power to other facilities that are not controlled by the present invention, such as fire-fighting and smoke-exhaust equipment and emergency elevators. The self-power supply 54 cannot cope with a load change when the power demand of the facility suddenly increases or decreases in a short time, and the power supply amount of the self-power supply 54 is insufficient or a phenomenon that the power supply amount is surplus occurs. If the increase or decrease in the amount of power supply exceeds the allowable range of the performance of the self-power supply 54, the (self-power supply control unit 55) performs an emergency stop measure or prevents the self-power supply 54 and the power line from being The circuit may be interrupted by the connected circuit breaker. The central management control device 10 sets a threshold value indicating the power supply performance of the self power supply 54 so that the self power supply 54 does not exceed the allowable increase / decrease range of the power supply amount due to the increase / decrease in demand power generated at the output 20 of the mode signal. The power supply is constantly monitored and judged. In addition to the determination based on the threshold value, a determination may be made by inputting a voltage drop signal, an overcurrent signal, or the like from the control unit of the self power supply 54. Specifically, the central control apparatus 10 monitors the power supplied from the self-power supply 54 accompanying the change in the demand power generated at the time of delay output 21 of the mode signal, and predicts 33 the amount of change per unit time. When it is determined that the allowable range (predetermined change amount range) of the self-power supply 54 is exceeded, the process 34 for stopping the delay output of the mode signal is performed, or in the state where the self-power supply 54 is supplying power. In order to preferentially supply power to specific important equipment such as a security device when it is determined that the power demand of the other equipment not controlled by the invention increases and the supply power of the self-power supply 54 exceeds the allowable range, A shut-off mode is output 35 to a specific distribution board with a low priority set in the central management control device 10 to shut off the remote control breaker and reduce demand power.

  FIG. 2 shows the configuration of the power supply system.

  A service line 50 is connected to a commercial power source 51 outside the building. In the building, a power failure detector 52 that detects a power failure of the commercial power supply 51, a fire detector 56 that detects a fire in the building, a self-power source 54 connected to the emergency line 53, and a self-power source control that controls the self-power source 54. A portion 55 is provided. The central management control apparatus 10 is connected to the power failure detector 52, the self-power supply control unit 55, and the fire detector 56 via a network of signal lines, and is in a state where it can receive a status signal of each facility.

  The self-power supply 54 may be a generator using a diesel engine or a gas turbine engine, or may be a storage battery. A plurality of self-power supplies 54 may be connected to an emergency line 53 or a low-voltage line on the secondary side of a transformer (transformer) TR through a circuit breaker.

  When the fire detector 56 detects a building fire, the fire detector 56 validates the fire detection signal. When the power failure detector 52 detects a power failure of the commercial power supply 51, the power failure detector 52 validates the power failure detection signal. The self-power supply control unit 55 controls the self-power supply 54 and outputs states such as activation of the self-power supply 54, voltage establishment, and remaining energy. The fire detector 56, the power failure detector 52, the self-power supply control unit 55, and the circuit breaker CB may be connected to the centralized management control device 10 via a central monitoring device provided in the building monitoring system. .

  The service line 50 is connected to a plurality of distribution boards PB that can supply power to the general load and the BCP load, and a circuit breaker CB1 that can be opened and closed by the centralized management control device 10, so that the line can be controlled. In addition, the emergency line 53 is capable of supplying power to the safety load 113 and the disaster prevention load 114, and is connected to the circuit breaker CB2 that can be opened and closed by the centralized management control device 10, so that the line can be controlled.

Further, the CB 3 that can connect the service line 50 and the emergency line 53 by an opening / closing operation can be opened / closed by a signal output from the central management control device 10. Therefore, the power supplied from the self power supply 54 can be sent to the service line 50. Moreover, the electric power supplied from the commercial power source 51 can be sent to the security load and the disaster prevention load.

  The plurality of distribution boards PB connected to the service line 50 have a circuit that can branch and supply power to the general load circuit and the BCP load circuit. Remote control breakers RB1 and RB2 are arranged in the general load circuit and the BCP load circuit, respectively. The remote control breakers RB1 and RB2 perform an opening / closing operation according to a signal output from the control unit CU arranged in the distribution board PB. The general load circuit includes a plurality of sub-breakers, and the plurality of sub-breakers are respectively connected to the plurality of general loads L1. The BCP load circuit includes a plurality of sub-breakers, and the plurality of sub-breakers are respectively connected to the plurality of BCP loads L2. When a plurality of general loads L1 and a plurality of BCP loads L2 respectively corresponding to a plurality of usage spaces are connected to one distribution board PB, the distribution board PB includes three or more remote control breakers RB. You may go out.

  Each of the control units CU1, CU2,... CUn refers to the RB setting value table 22 set and registered for each mode in advance by the input of the mode signal from the centralized management control device 10, and according to the open / close setting value, the remote control breaker RB1, The breaking current set value can be changed by opening / closing RB2.

  Further, the control unit CU constantly measures the current value in the distribution board PB with the current transformer CT and the meter M, and the RB set value table 22 stored in the storage area in the control unit CU from the centralized management controller 10. The remote control breaker RB1 or the remote control breaker RB2 can be cut off when the cut-off current set value is always referred to and the measured current value exceeds the cut-off current set value.

  The centralized management control device 10 can set a cutoff current set value for each control unit in advance for all control units CU in advance by input from the terminal device 111, so the power supply capacity of the self-power supply 54 for disaster prevention load can be set. The power supplied to the distribution board PB can be set so as not to exceed.

  As a result, when receiving the power failure signal from the power failure detector 52, the centralized management control device 10 instructs the CB 1 to open, cuts off the service line 50 from the commercial power source 51, and the self power source control unit 55 sends the self power source 54. After receiving the start signal and the voltage establishment signal, the power supply from the self-power supply 54 to the emergency line 53 is established by the CB2 closing operation command, and further closed to the CB3 when there is no fire signal from the fire detector 56. The power supply is supplied to the service line 50 by commanding the operation, and the mode signal is output to each control unit CU to adjust the power supplied to the distribution board PB. The power supply to the distribution board PB is established so as not to exceed the power supply capacity. In the case of an existing building, it is also possible to connect the existing distribution board 65 to the remote control breaker RB21 and supply power to the general load L21 connected to the existing distribution board 65.

  Hereinafter, a method for dividing the distribution board PB will be described.

  FIG. 3 shows the structure of the divided distribution board PB.

  In this figure, the left side is a front view of the divided distribution board PB, and the right side is a right side view of the divided distribution board PB. The distribution board PB is divided into a main board 60 for receiving power supply from the power line, a branch board 61 for supplying power to the BCP load, and a control board 62 for controlling the remote control breaker. Also good. Thereby, the installer of distribution board PB can carry in and install by dividing distribution board PB. When installing a power supply system in an existing building, the existing distribution board 65 and the existing equipment 66 shown in FIG. 5 are often installed in spaces such as EPS (Electric Pipe Space) inside walls of the existing building, and are often narrow. The distribution board PB is devised so that it can be divided and installed because there are conditions such as the door being a carry-in route being small. The main board 60, the branch board 61, and the control board 62 are provided with a lid 63 and a key 64, and can be locked.

  FIG. 4 shows a configuration of the main board 60, the branch board 61, and the control board 62 in the case where an existing distribution board is present.

  The master board 60 includes a terminal block TBa, a manual breaker (sub-breaker) MCBa, a current transformer CT, a remote control breaker RB1, a terminal block TBb, a meter M, and a case 160 (first case) for storing them. Including. A terminal block TBa is connected to the service line 50. A breaker MCBa and a current transformer CT are sequentially connected to the terminal block TBa via electric wires (distribution board electric wires). The electric wire connected to the manual breaker MCBa branches into two electric wires (branch wires). A remote control breaker RB1 and a terminal block TBb are sequentially connected to one of the electric wires. A branch board 61 is connected to the other electric wire. An existing distribution board 65 is connected to the terminal block TBb. A meter M is connected to the current transformer CT by a signal line (broken line in the figure). The manual breaker MCBa prevents overcurrent.

  Branch board 61 includes a remote control breaker RB2, a plurality of manual breakers MCBb, and a case 161 (second case) for storing them. A remote control breaker RB2 is connected to an electric wire from the manual breaker MCBa of the main board 60. From the remote control breaker RB2, a plurality of electric wires are branched and a plurality of manual breakers MCBb are connected. A plurality of BCP loads are respectively connected to the plurality of manual breakers MCBb.

  The control panel 62 includes a voltage regulator AVR, a manual breaker MCBc, a control unit CU, and a case 162 (third case) for storing them. A voltage regulator AVR is connected to the electric wire from the UPS 115. A plurality of manual breakers MCBc are connected to the voltage regulator AVR. A control unit CU, a meter M, a remote control breaker RB1, and a remote control breaker RB2 are connected to the plurality of manual breakers MCBc through wires. Thereby, even during a power failure, power is supplied to the control unit CU, the meter M, the remote control breaker RB1, and the remote control breaker RB2. Further, the control unit CU, the meter M, the remote control breaker RB1, and the remote control breaker RB2 are connected by signal lines (broken lines in the figure) and are in a state where various signals can be input and output.

  The existing distribution board 65 includes a terminal block TBe and a plurality of manual breakers MCBe. A terminal block TBe is connected to the electric wire from the terminal block TBb of the main board 60. A plurality of manual breakers MCBe are connected to the terminal block TBe. A plurality of general loads are respectively connected to the plurality of manual breakers MCBe. When the number of manual breakers MCBe in the existing distribution board 65 is larger than the number of manual breakers MCBb in the branch board 61, the dimensions of the branch board 61 can be made smaller than that of the existing distribution board 65.

  FIG. 5 shows a method for installing the main board 60, the branch board 61, and the control board 62.

  In this figure, the upper side is a front view showing the EPS inner wall surface. An existing distribution board 65, existing equipment 66, and the like are installed on the EPS inner wall surface before the distribution board PB is installed.

  In this figure, the lower side is a plan view showing a floor plan of a building. The main board 60 may be installed in the vicinity of the existing distribution board 65, and the branch board 61 and the control board 62 may be installed in a vacant space inside the EPS, or in a space such as an office room by being locked.

  The master board 60, the branch board 61, and the control board 62 are basically installed on the same floor. Since wires such as electric wires and signal lines connecting the main board 60, the branch board 61, and the control board 62 are thinner than the service line 50, the connection work for connecting the wiring is performed in the height direction along the EPS of the building. Compared with the construction of the service line 50 to be performed, it is simplified and shortened. Further, since the service line 50 is connected to the main board 60 last, it is not necessary to turn off the commercial power source 51 during the installation work of the main board 60, the branch board 61, and the control board 62. It can be done without stopping important devices such as servers. Therefore, connection work is possible even on weekdays when there are office workers in the building, and the construction period is shortened compared to power line work involving power outages limited to nights and holidays.

  The construction of the connection between the main board 60 and the service line 50 should be carried out on the day of a power outage, etc. required once a year for building maintenance after the main board 60, the branch board 61 and the control board 62 are installed. Can do. In this construction, after disconnecting the service line 50 connected to the existing distribution board 65, the main line 60 is connected to the main board 60 installed in the vicinity, and the electric wires 67 prepared in advance are connected to the main board 60. Since the electrical panel 65 is connected, the process is completed in a short time.

  The relationship between the building structure and the power supply system will be described below.

  FIG. 6 shows the arrangement of the power supply system in the building.

  The terminal device 111, the centralized management control device 10, and the UPS 115 are installed in a disaster prevention center in a building. Distribution board PB is installed in EPS of each floor. A signal line is wired from the central management control device 10 to each distribution board. Wires for supplying electric power necessary for the operation from the UPS 115 to the terminal device 111, the centralized management control device 10, and the distribution board PB are wired, and operate for a certain period of time even when the commercial power supply 51 has a power failure. Thereby, even when a power failure occurs, the centralized management control device 10 can perform control to shut off the remote control breaker arranged in the distribution board PB.

  The centralized management control device 10 can distribute the cut-off current setting value of each distribution board PB within the range of surplus power according to the input to the terminal device 111 by the administrator. Thereby, the electric power supply system can concentrate and supply the surplus electric power of the whole building to a specific floor. For example, a power supply system can effectively use limited power by concentrating and supplying surplus power to a floor of a disaster countermeasure headquarters or a server room.

  One floor may be divided into a plurality of usage spaces, and a distribution board PB may be installed in each usage space. In this case, the power supply system can concentrate and supply power to a local unit smaller than the floor.

  Hereinafter, a case where the power supply system is applied to a regional energy management system will be described.

  In recent years, regional energy management work has been developed to allow power and thermal energy to be interchanged between buildings in the region, such as receiving commercial power collectively in the region, and applying the power supply system of this embodiment to the regional energy management system Thus, it is possible to control the power supply of a plurality of buildings from the energy center.

  FIG. 7 shows the configuration of the regional energy management system.

  In the area C1, buildings B1, B2,... B5 and an energy center EC1 are provided. In the area C2, buildings B6, B7,... B10 and an energy center EC2 are provided. The regional power supply system controls the power supply of a plurality of buildings B in the regions C1 and C2. A central management control device 10 is installed in the energy center EC of each region C. The central management control apparatus 10 is connected to a distribution board PB installed in each of a plurality of buildings B in the same area via wired communication or wireless communication.

  The central management control device 10 is connected to the cloud server 116 outside the areas C1 and C2 via the Internet. The functions, setting values, and stored data of the central management control device 10 are backed up by the cloud server 116. By using such a dual system for the power supply system, the system can be more resilient to disasters, and can be remotely handled by an administrator in another region in the event of an emergency response such as a disaster. For example, when the area C1 suffers a disaster, the manager of the energy center in the area C2 that has not suffered a disaster can support the area C1 as an emergency response. Examples of emergency responses include monitoring the status of the distribution panel PB to prepare for unforeseen circumstances such as equipment abnormalities, adjusting the cut-off current setting value to reduce unnecessary power, and fuel used for self-power supply For example, when the amount of fuel is reduced, fuel procurement is arranged and delivery is instructed.

  Hereinafter, information used by the power supply system will be described.

  Here, the mode determination 15 in the logical operation processing 102 will be described.

  FIG. 8 shows the mode determination 15.

  The mode determination 15 has condition information for each mode. The condition information for one mode includes a mode name, a mode number, and a mode condition. The mode name indicates the name of the mode. The mode names are, for example, normal mode, cutoff mode, BCP mode, manual mode, maintenance mode, and the like. The cut-off mode may be a power failure, a power failure, a fire, a remaining capacity limit, or a power recovery. The mode number is an identifier indicating the mode, and is transmitted as a mode signal from the centralized management control device 10 to the control unit CU. Note that the device status after control in FIG. 8 means that the system controls the devices of the circuit breaker CB1, circuit breaker CB2, circuit breaker CB3, remote control breaker RB1, and remote control breaker RB2. It shows the operating state after the mode is adapted.

  The mode condition is a condition for shifting to the mode or enabling the transition. The mode conditions are a power failure detection signal indicating the state of the commercial power source 51, a fire occurrence signal indicating the state of the building, a voltage establishment signal of the self power source indicating the state of the self power source 54, and an emergency indicating the state of the emergency line 53 It is defined by the circuit breaker CB3 connection information related to the service line and the remaining amount alarm indicating the determination result of the remaining operation time of the self power supply 54. The power failure detection signal becomes valid (ON) when a power failure of the commercial power source 51 is detected by the power failure detector 52. The fire occurrence signal becomes effective when a fire in the building is detected by the fire detector 56. The voltage establishment signal becomes effective when the self-power supply control unit 55 detects that the voltage of the self-power supply 54 is established and falls within a preset voltage range. The emergency line connection information is obtained when the circuit breaker CB3 is turned on (ON) by the central management control device 10 and the distribution board PB is connected to the emergency line 53, or the safety load and the disaster prevention load are the regular line 50. Enabled when connected to. The remaining amount alarm becomes effective when it is detected by the self-power supply control unit 55 or the centralized management control device 10 that the remaining operation time of the self-power supply 54 is less than or equal to a preset remaining operation time threshold. The remaining operating time threshold is, for example, a value obtained by adding a margin to the operating time of the legal disaster prevention load 114. Note that the remaining energy of the self-power supply 54 may be used instead of the remaining operating time. The remaining amount alarm may be effective when it is detected that the remaining energy amount is outside a preset remaining amount range (for example, a preset remaining energy threshold value).

  The logic operation processing 102 can shift the mode to the normal mode when the power failure detection signal is OFF, the fire occurrence signal is OFF, and the connection information of the circuit breaker CB3 is ON. Further, the logical operation processing 102 is performed when the power failure detection signal is ON, the fire occurrence signal is OFF, the voltage establishment signal is OFF, and the connection information of the circuit breaker CB3 is OFF. It can be determined and the mode can be shifted to the cutoff mode. Further, the logical operation processing 102 determines that the power failure is accompanied by a fire when the power failure detection signal is ON, the fire detection signal is ON, and the voltage establishment signal is ON, and the mode is shifted to the cutoff mode. be able to. Further, the logical operation processing 102 may determine that the amount of fuel is low and shift the mode to the cutoff mode when the power failure detection signal is ON, the voltage establishment signal is ON, and the remaining amount alarm is ON. it can. Further, the logical operation processing 102 shifts the mode to the cut-off mode when the power failure detection signal is OFF and the voltage establishment signal is ON in response to an input indicating power recovery to the terminal device 111 by the administrator. be able to. Further, the logical operation processing 102 includes a power failure detection signal ON, a fire occurrence signal OFF, a voltage establishment signal ON, a circuit breaker CB3 connection signal ON, and a remaining amount alarm. When is OFF, the mode can be shifted to the BCP mode. Also, the logical operation processing 102 can shift the mode to the manual mode when the fire occurrence signal is OFF in response to an input indicating the manual mode to the terminal device 111 by the administrator. Further, the logical operation processing 102 can shift the mode to the maintenance mode in response to an input indicating the maintenance mode to the terminal device 111 by the administrator.

  Thereby, the centralized management control apparatus 10 can make it transfer to an appropriate mode according to the state of the fire of a building, the commercial power supply 51, and the self-power supply 54. FIG.

  FIG. 9 shows a registration method of the RB set value table.

  The switching setting value and the breaking current setting value in each of the plurality of modes are registered in the centralized management control device 10 as an RB setting value table based on an input to the terminal device 111 by the administrator. The centralized management control device 10 transmits the switching setting value and the cutoff current setting value to the plurality of control units CU. The plurality of control units CU receive the respective opening / closing setting values and breaking current setting values and store them as the RB setting value table 22.

  FIG. 10 shows an RB set value table.

  The RB set value table 22 has an entry for each mode. The entry of one mode includes the value of the mode signal, the open / close setting value of each remote control breaker RB, and the cutoff current setting value. The open / close setting value is represented by at least one of open (shutoff) and close (close) for each remote control breaker RB. The cut-off current set value is represented by current [A].

  When each control unit CU receives the mode signal from the centralized management control device 10, it outputs the opening / closing operation signal according to the opening / closing setting value corresponding to the mode signal, thereby operating the remote control breaker RB, and the cutoff current corresponding to the mode signal. By updating and setting the set value, the current measurement value of the meter M is constantly compared with the cut-off current set value. When the control unit CU determines that the measured current value exceeds the breaking current set value, the control unit CU controls the remote control breaker RB in the on state to the breaking state. For example, in the BCP mode, the control unit CU1 of the distribution board PB1 controls the remote control breaker RB11 to be in the cutoff state and the RB12 to be in the on state, and the total current flowing through the remote control breaker RB is the cutoff current set value 15 [A] When it is determined that the value exceeds the remote control breaker RB12 in the on state, the remote control breaker RB12 is controlled to be shut off. Thereby, the distribution board PB1 can supply power to the general load L11 and the BCP load L12 up to 40 [A] in the normal mode, and supplies power to the BCP load L12 up to 15 [A] in the BCP mode. be able to. For example, in the BCP mode, the control unit CU2 of the distribution board PB2 controls the remote control breaker RB21 and the remote control breaker RB22 to be in the on state, and the total current flowing through the remote control breaker RB is 30 [A ], The remote control breaker RB21 and the remote control breaker RB22 that are in the on state are controlled to be in a cutoff state. Thereby, the distribution board PB2 can supply power to the general load L21 and the BCP load L22 up to 60 [A] in the normal mode, and 30 power to the general load L21 and the BCP load L22 in the BCP mode. [A] can be supplied. In this case, the distribution board PB2 can supply half power to the same load as in the normal mode in the BCP mode. For example, the control unit CU3 of the distribution board PB3 controls the remote control breaker RB31 and the remote control breaker RB32 to be in a cut-off state in the BCP mode. Thereby, the distribution board PB3 can supply electric power to 60 [A] to the general load L31 and the BCP load L32 in the normal mode. In the BCP mode, power is not supplied to the load. For example, in the BCP mode, the control unit CU4 of the distribution board PB4 controls the remote control breaker RB41 in the cutoff state and the RB42 in the on state, and the total current flowing through the remote control breaker RB is the cutoff current setting value 30 [A]. If it is determined that the value exceeds the remote control breaker RB42 in the on state, the remote control breaker RB42 is controlled to be shut off. Thereby, the distribution board PB4 can supply power to the general load L41 and the BCP load L42 up to 40 [A] in the normal mode, and supplies power to the BCP load L42 up to 30 [A] in the BCP mode. be able to. The power supplied to the BCP load L42 is set by setting the cutoff current setting value of the BCP mode in the RB setting value table 22 of the control unit CU4 to be larger than the cutoff current setting value of the BCP mode in the RB setting value table 22 of the control unit CU1. Can be distributed more than the power supplied to the BCP load L12. Further, in the RB set value table 22 of the control unit CU1, the RB12 open / close set value in the BCP mode may indicate the on state, and the cutoff current set value may indicate 0. In this case, the RB 12 is in a cut-off state during the BCP mode. Further, in the RB setting value table 22 of the control unit CU2, each setting value in the normal mode may be equal to each setting value in the BCP mode. In this case, the distribution board PB2 performs the same control in the normal mode and the BCP mode.

  As a result, the centralized management control device 10 can freely set the plurality of remote control breakers RB of the plurality of distribution boards PB under the condition that the total of all cut-off current set values is equal to or less than the power supply capacity. Power can be supplied without waste regardless of the capacity. For example, the central management control device 10 distributes the power supply capability to a plurality of floors in the normal mode, and concentrates the power supply capability on the distribution board PB such as a specific floor or a specific use space in the BCP mode. Can do.

  Note that the central management control device 10 may transmit an open / close setting value and a cutoff current setting value corresponding to the mode to the control unit instead of the mode signal. In this case, the control unit CU does not store the RB set value table 22 but stores the received open / close set value and cutoff current set value.

  Hereinafter, a distribution board of a modification will be described.

  FIG. 11 shows a configuration of a distribution board according to a modification.

  In this figure, the upper figure is an example in which the components, circuits, and functions constituting the main board 60, the branch board 61, and the control board 62 are housed in one case, and the distribution board PB1 has three current transformers. CT11, CT12, CT13, three meters M11, M12, M13, three remote control breakers RB11, RB12, RB13, and a control unit CU1 are included. The wires from the service line 50 are branched into three wires (branch wires), and three current transformers CT11, CT12, and CT13 are connected to each of the three wires. Three meters M11, M12, and M13 are connected to the three current transformers CT11, CT12, and CT13, respectively. A general load L11, a BCP load L12, and a BCP load L13 are connected to the three remote control breakers RB11, RB12, and RB13, respectively. The control unit CU1 is connected to three meters M11, M12, M13 and three remote control breakers RB11, RB12, RB13. As shown in the figure below, the CU 1 is installed outside the distribution board PB and can control a plurality of distribution boards PBn. Further, the number of current transformers CT, meters M, remote control breakers RB, and loads in the distribution board PB is not limited to three.

  In the same manner as the dividing method described above, the distribution board PB1 of this modification can be divided into one main board 60, two branch boards 61, and one control board 62. . In this case, main board 60 includes current transformer CT11, meter M11, and remote control breaker RB11. The first branch board 61 includes a current transformer CT12, a meter M12, and a remote control breaker RB12. Second branch board 61 includes current transformer CT13, meter M13, and remote control breaker RB13. The control panel 62 includes a control unit CU1.

  With this configuration, the meters M11, M12, and M13 measure the currents flowing through the remote control breakers RB11, RB12, and RB13, respectively.

  FIG. 12 shows an RB setting value table of a distribution board according to a modification.

  The entry of one mode in the RB set value table 22 of the modified example includes the value of the mode signal, the open / close set value of each remote control breaker RB, and the cutoff current set value of each remote control breaker RB.

  The control unit CU1 in the distribution board PB1 controls the remote control breaker RB11 to be in a cut-off state when the measured value of the meter M11 exceeds the cut-off current set value of the remote control breaker RB11. Similarly, the control unit CU1 controls the remote control breaker RB12 to be in a cut-off state when the measured value of the meter M12 exceeds the cut-off current set value of the remote control breaker RB12. Similarly, the control unit CU1 controls the remote control breaker RB13 to be in a cutoff state when the measured value of the meter M13 exceeds the cutoff current set value of the remote control breaker RB13. Thereby, the centralized management control apparatus 10 can set the breaking current set value for each remote control breaker RB.

  Hereinafter, the operation of the power supply system during a power failure will be described.

  FIG. 13 shows the operation of the power supply system during a power failure.

  When the remaining amount of fuel and the amount of electricity stored in the self-power supply are sufficient, a power failure has occurred, and no fire has occurred, the central management control device 10 performs control in the BCP mode. Note that the BCP mode is not executed by the self power remaining operation time calculation 32 when the remaining amount of fuel or the amount of stored power of the self power source is insufficient or insufficient, but it is generally rare.

  The central management control device 10 receives a power failure detection signal from the power failure detector 52 (step S10). When there is no power failure detection signal, the centralized management control device 10 repeats step S10 (step S10: No). When there is a power failure detection signal, the central management control device 10 starts control of the circuit breaker CB on the power line (step S10: Yes). The circuit breaker CB1 between the commercial power supply 51 and the service line 50 and the circuit breaker CB3 between the service line 50 and the emergency line 53 are controlled to be disconnected (step S11), and the centralized control device 10 performs logical operation processing. When the fire detection signal is received from the fire detector 56 (step S12: Yes), it is determined that the mode is shifted to the shut-off mode (step S13), and when there is no fire detection signal (step S12: No) It is determined that the mode is changed to the BCP mode (step S31, step S41).

  When the mode shifts to the cut-off mode, the self-power supply 54 is activated, so the central management control device 10 receives a self-power supply activation signal from the self-power supply control unit 55 (step S13). Since the self-power control unit 55 outputs a voltage establishment signal when the necessary voltage is established after the self-power supply 54 is activated, the central management control device 10 receives the voltage establishment signal (step S14). The central management control device 10 supplies power to the safety load 113 and the disaster prevention load 114 by controlling the circuit breaker CB2 between the self power supply 54 and the emergency line 53 to be turned on (step S15) (step S16). . Further, the central management control device 10 outputs a cutoff mode signal to each control unit CU (step S17). Here, the centralized management control apparatus 10 optimizes the priority of the output destination control unit CU and the output order (step S18), and outputs the timing for outputting the mode signal for each control unit CU in advance. A delay output 21 is output that is shifted by time intervals (step S19). The output time interval can be set arbitrarily. When each control unit CU receives the cutoff mode signal, each control unit CU reads the opening / closing setting value of the RB setting value table 22 stored in the storage area of the control unit CU, and outputs a signal for causing the remote control breaker RB to perform an opening / closing operation (step S20). . In the cutoff mode, the control unit CU controls all the remote control breakers RB to the cutoff state (step S21).

  If it is determined that the mode shifts to the BCP mode (step S12: No), the self-power supply 54 is activated, so the central management control device 10 receives a self-power supply activation signal from the self-power supply control unit 55 (step S31). . Since the self-power control unit 55 outputs a voltage establishment signal when the necessary voltage is established after the self-power supply 54 is activated, the centralized management control device 10 receives the voltage establishment signal (step S32). The centralized management controller 10 controls the circuit breaker CB2 between the self power supply 54 and the emergency line 53 to be turned on (step S33), and turns on the circuit breaker CB3 that connects the service line 50 and the emergency line 53. (Step S34), it is possible to supply power from the self-power supply 54 to the distribution board PB through the service line 50. At this time, the disaster prevention load 114 does not operate and does not consume power.

  The centralized management control device 10 performs the logical operation processing 102 and outputs a cut-off mode signal to each control unit CU in order to reduce the influence of the inrush current from the self power supply 54 on the load (step S41), All remote control breakers RB (RB11, RB12, RB21, RB22,... RBn1, RBn2) in all distribution boards PB are controlled to be cut off, and all loads connected to all distribution boards PB are cut off (step) S42). This blocking operation is performed in the same manner as (Step S19 to Step S21).

  When the central management control device 10 receives a signal indicating that the circuit breaker CB3 has been turned on, the central management control device 10 performs a logic operation process 102, and calculates the surplus power and the remaining operation time of the self-power supply 54, and the control unit that is the output destination of the BCP mode signal CU priority and output order are optimized (step S44). For example, if the importance of a BCP load connected to a certain distribution board PB is high, this means that the distribution board PB has a high priority, and the central management control device 10 preferentially powers the distribution board PB. In order to supply power, processing such as not supplying power to the distribution board PB connected to an unnecessary load is performed based on the surplus power and the remaining operation time of the self-power supply 54. When the central control apparatus 10 determines an output destination control unit CU, the control unit CU selects the output unit in order from the control unit CU having the highest priority, shifts the output timing by the output time interval, and transfers the BCP to the selected output destination. A delay output 21 for outputting a mode signal is performed (step S45).

  When each control unit CU receives the BCP mode signal from the centralized control device 10, each control unit CU sends a signal for causing the remote control breaker RB to open / close in accordance with the open / close setting value of the RB setting value table 22 stored in the storage area of the control unit CU. Output (step S46) and update the breaking current set value (step S47). In the example of this flow, the control unit CU inputs the remote control breakers RB12, RB22,... RBn2 (step S48).

  In step S34, electric power is supplied from the self-power supply 54 to the distribution board PB. In step S48, the remote control breaker RBn2 is turned on, whereby electric power is supplied to the BCP load L2 connected to the remote control breaker RBn2 (step S34). S49).

  When the central monitoring device described above is provided for building management, the central monitoring device controls the circuit breaker CB1 and the like on the basis of the power failure detection signal, thereby cutting off the service line 50 and performing self-power control. The self power supply 54 may be activated by controlling the unit 55.

  According to the above operation, the power supply system can supply power from the self-power supply 54 to the security load 113 and the BCP load L2 when a power failure occurs and a fire does not occur. The power supply system can supply power from the self-power supply 54 to the security load 113 and the disaster prevention load 114 when a power failure occurs and a fire occurs.

  Hereinafter, some specific examples of the operation of the power supply system in an emergency will be described.

  First, a case where a power failure has occurred and no fire has occurred will be described.

  FIG. 14 shows the operation of the power supply system when the remaining amount of fuel and the amount of electricity stored in the self-power supply are sufficient, a power failure has occurred, and no fire has occurred.

  This figure shows monitoring control devices such as a power failure detector 52, a fire detector 56, a self-power supply control unit 55, a terminal device 111, a centralized management control device 10, a circuit breaker CB, a control unit CU, and a remote control breaker. The cooperative operation with RB is shown.

  When the power failure detector 52 detects a power failure of the commercial power supply 51, the power failure detection signal is validated (step S101). When the power failure detection signal is validated (step S102), the centralized management control device 10 activates the circuit breakers CB1, And the circuit breaker CB3 is interrupted | blocked (step S103) and the terminal device 111 is made to display that the power failure generate | occur | produced (step S104). At this time, the central management control device 10 may cause the speaker 112 to generate an alarm sound. When the fire detector 56 invalidates the fire detection signal (step S105), the central management control device 105 recognizes that no fire has occurred (step S106), and a power failure occurs due to logical operation processing. Since the fire does not occur, the voltage of the self-power supply is not established, and the circuit breaker CB3 is in the cut-off state, the mode is shifted to the cut-off mode (power failure) (step S107), and the current mode is It is displayed on the terminal device 111 that it is the interruption mode (step S108). Thereafter, the central management control device 10 reads the output destination order setting (step S109), and delays and outputs the cutoff mode signal according to the output destination order setting (step S110). For example, when the output destination order setting indicates the order of the control units CU1, CU2, and CU3, and the output time interval is 2 seconds, the centralized management control device 10 outputs a cutoff mode signal to the control unit CU1, After 2 seconds, the cutoff mode signal is output to the next control unit CU2, and after 2 seconds, the cutoff mode signal is output to the next control unit CU3.

  When receiving the cutoff mode signal (Step S111), the control unit CU outputs a cutoff signal to all connected remote control breakers (Step S112). When receiving the cutoff signal, the remote control breaker shuts down the circuit (step S113).

  The self-power supply control unit 55 activates the self-power supply 54 in response to the power failure detection signal and validates the self-power supply activation signal indicating the activation of the self-power supply 54 (step S114). When the self-power supply activation signal is validated (step S115), the centralized management control device 10 displays on the terminal device 111 that the self-power supply 54 has been activated (step S116).

  The self-power supply 54 establishes a voltage from a power failure detection signal to a predetermined activation time (for example, 40 seconds), and validates the voltage establishment signal (step S117). When the voltage establishment signal is validated (step S118), the central management control device 10 displays on the terminal device 111 that the voltage of the self power supply 54 has been established (step S119).

  The central management control device 10 connects the self power supply 54 and the emergency line 53 by turning on the circuit breaker CB2 (step S120). Thereafter, the centralized management control device 10 validates the emergency line connection information (step S121), and displays on the terminal device 111 that the system is the emergency line 53 (step S122). The circuit breaker CB3 is turned on to connect the emergency line 53 and the service line 50 (step S123), the connection information of the circuit breaker CB3 is validated (step S124), and the emergency line 53 and service line 50 are connected. The connection is displayed on the terminal device 111 (step S125). Note that the central monitoring device may perform circuit breaker breakage or the like.

  The centralized management control device 10 causes a power failure, no fire, and the circuit breaker CB3 is in the on state, the voltage of the self power supply 54 is established, and the remaining power supply 54 Since the operation time is longer than the limit value, the mode is shifted to the BCP mode (step S126), and the terminal device 111 is displayed that the current mode is the BCP mode (step S127). Thereafter, the central control apparatus 10 reads the output destination order setting (step S128), and delays and outputs the BCP mode signal according to the output destination order setting (step S129). Here, the central management control device 10 may select the output destination control unit CU by the output destination priority processing 18.

  When receiving the BCP mode signal (step S130), the control unit CU reads the BCP mode cutoff current setting value (step S131), and outputs a cutoff signal to the remote control breaker RB1 (step S132). When receiving the cutoff signal, remote control breaker RB1 shuts off the general load circuit (step S133). Thereafter, the control unit CU outputs a closing signal to the remote control breaker RB2 (step S134). When receiving the making signal, remote control breaker RB2 turns on the BCP load circuit (step S135). The shut-off signal and the closing signal are output to the remote control breakers RB1 and RB2 at preset operation time intervals (for example, 2 seconds).

  Thereafter, the control unit CU constantly acquires the current measurement value of the meter M, and determines that the current measurement value has exceeded the breaking current set value for a preset time (for example, 10 seconds) (step S136). A cutoff signal is output to remote control breaker RB2 (step S137). When receiving the cutoff signal, remote control breaker RB2 shuts off the BCP load circuit (step S138).

  Thereafter, the control unit CU outputs an RB state signal indicating that the remote control breaker RB2 is shut off (step S139). When the central management control device 10 receives the RB state signal (step S140), the central management control device 10 causes the terminal device 111 to display a cut-off alarm indicating that the remote control breaker RB2 is cut off (step S141). At this time, the central management control device 10 may cause the speaker 112 to generate an alarm sound.

  Thereafter, the administrator confirms the usage state of the BCP load, and adjusts to reduce the demand power (current) if the load is large. Thereafter, when the terminal device 111 receives an input of a reset operation of the remote control breaker RB2 by the administrator (step S142), the centralized management control device 10 outputs a reset command to the control unit CU (step S143). When receiving the reset command, the control unit CU outputs a closing signal to the remote control breaker RB2 (step S144). When receiving the input signal, remote control breaker RB2 turns on the BCP load circuit again (step S145).

  FIG. 15 shows the operation of the power supply system when the remaining capacity of the self-power supply after the BCP mode is reached or when the commercial power supply is restored.

  Thereafter, the centralized management control device 10 receives power supply information indicating the state of the self power supply 54 from the self power supply control unit 55 (step S153), and calculates the remaining operating time of the self power supply 54 based on the received information. If it is determined that the remaining operating time is less than or equal to the limit value, the remaining amount alarm is validated (step S154). Thereafter, the central management control device 10 shifts the mode to the cut-off mode (at the time of the remaining capacity limit) by logical operation processing (step S156). At this time, the central management control device 10 may cause the speaker 112 to generate an alarm sound. The subsequent operation in the blocking mode (steps S157 to S163) is the same as the operation in the blocking mode described above (steps S108 to S113). The central management control device 10 shuts off the circuit breaker CB3 (step S164), validates the circuit breaker information of the circuit breaker CB3 (step S165), and displays on the terminal device 111 that the emergency line 53 and the service line 50 have been cut off. (Step S166).

  When the commercial power supply 51 is restored, the power failure detector 52 invalidates the power failure detection signal (step 167), and when the power failure detection signal is invalidated (step S168), the central management control device 10 turns off the circuit breaker CB3. It is shut down (step S169), and the power recovery is displayed on the terminal device 111 (step S170). Thereafter, the centralized management control device 10 shifts the mode to the cut-off mode (at power recovery) by logical operation processing (step S171). At this time, the centralized management apparatus 10 may cause the speaker 112 to generate an alarm sound. Thereafter, the operation in the blocking mode (steps S172 to S177) is the same as the operation in the blocking mode described above (steps S108 to S113).

  Thereafter, the centralized management control device 10 shuts off the circuit breaker CB2 to cut off the emergency line 53 and the service line 50 (step S178), validates the breaker information of the circuit breaker CB2 (step S179), and uses the emergency line. It is displayed on the terminal device 111 that 53 interrupted | blocked (step S180). Then, by turning on the circuit breakers CB1 and CB3 (step S181), the system for supplying power to the distribution board PB is switched from the emergency line 53 to the service line 50. Note that the central monitoring device may turn on the circuit breakers CB1 and CB3.

  When the central control device 10 switches the system to the service line 50 under the control of the circuit breaker CB (step S181), the emergency line connection information is invalidated (step S182), and the system is no longer the emergency line 53. Is displayed on the terminal device 111 (step S183).

  Thereafter, the administrator prepares for the normal mode. When the terminal device 111 receives an input of the normal mode operation by the administrator (step S184), the central management control device 10 reads the output destination order setting (step S185), and delays the normal mode signal according to the output destination order setting. (Step S186).

  When receiving the normal mode signal (step S187), the control unit CU reads the normal mode cutoff current setting value (step S188), and outputs a closing signal to all connected remote control breakers (step S189). When receiving the input signal, the remote control breaker turns on the circuit (step S190). When the control unit CU outputs an RB state signal indicating the state of the remote control breaker to the central management control device 10, the central management control device 10 displays on the terminal device 111 that the current mode is the normal mode (step S191). ).

  Next, a case where a fire occurs during the BCP mode will be described.

  FIG. 16 shows the operation of the power supply system when a fire occurs during the BCP mode.

  When the fire detector 56 detects that a fire has occurred, the fire detector 56 validates the fire detection signal (step S202). When the fire detection signal is validated (step S203), the centralized management control device 10 displays on the terminal device 111 that a fire has occurred (step S204). At this time, the central management control device 10 may cause the speaker 112 to generate an alarm sound. The centralized management control device 10 shifts the mode to the cut-off mode (at the time of power failure and at the time of fire) by logical operation processing (step S206), thereby shutting off all the remote control breakers and stopping the power supply to the BCP load, and , Make it possible to use surplus power as a disaster prevention load. The subsequent operation in the cutoff mode (steps S207 to S213) is the same as the above-described operation in the cutoff mode (steps S108 to S113). Thereafter, the circuit breaker CB3 is cut off to cut off the emergency line 53 and the service line 50 (step S214), and the breaker information of the circuit breaker CB3 is validated (step S215). The interruption is displayed on the terminal device 111 (step S216). Note that the central monitoring device may perform circuit breaker breakage or the like.

  The central management control device 10 sets an interlock (step S217).

  Thereafter, when the fire detector 56 detects that a fire has not occurred, the fire detector 56 invalidates the fire detection signal (step S218). When the fire detection signal is invalidated (step S219), the central management control device 10 displays on the terminal device 111 that no fire has occurred (step S220). At this time, the central management control device 10 may cause the speaker 112 to generate an alarm sound. The administrator checks the system status. When the terminal device 111 receives an input of a fire recovery operation by the administrator (S221), the centralized management control device 10 releases the interlock (step S222).

  After that, the central management control device 10 turns on the circuit breaker CB3 to connect the emergency line 53 and the service line 50 (step S223), validates the connection information of the circuit breaker CB3 (step S224), and uses the emergency line. 53 indicates that the terminal 53 is connected to the service line 50 (step S225). The subsequent operation in the BCP mode (steps S226 to S235) is the same as the operation in the BCP mode (steps S126 to S135) described above.

  Next, a case where a power failure occurs after a fire has occurred will be described.

  FIG. 17 shows the operation of the power supply system when a power failure occurs after a fire has occurred.

  First, the operation when a fire occurs (steps S301 to S303) is the same as the operation when a fire occurs (steps S202 to S204).

Thereafter, the operation when the commercial power supply fails (steps S304 to S307) is the same as the operation when the commercial power failure occurs (steps S101 to S104). The operation of starting the self-power supply after the power failure of the commercial power supply and establishing the voltage of the self-power supply (steps S308 to S313) is the same as the operation of self-power supply activation (S114 to S119) described above.

  The central management control device 10 shifts the mode to the cut-off mode (at the time of a power failure and at the time of a fire) by logical operation processing (step S314). The subsequent operation in the blocking mode (steps S315 to S320) is the same as the operation in the blocking mode described above (steps S108 to S113). Further, interlock is performed until the fire is recovered (step S321). Hereinafter, the central management control device 10 does not change the mode until the fire recovery operation is performed due to the interlock. Although the timing of the occurrence of a fire and the occurrence of a power failure of a commercial power supply may be mixed, the centralized management control device 10 is configured to combine a fire detection signal, a power failure detection signal, and a voltage establishment signal at the time of a power failure. The condition is met even if the timing of inputting each signal is different because the condition allows the transition to the shut-off mode at the time of a fire.

  The central management control device 10 connects the self power supply 54 and the emergency line 53 by turning on the circuit breaker CB2 (step S322). Thereafter, the centralized management control device 10 validates the emergency line connection information (step S323), and displays on the terminal device 111 that the system is the emergency line 53 (step S324). Note that the central monitoring device may turn on the circuit breaker CB2.

  When the fire is restored, the fire detector 56 invalidates the fire detection signal (step S325). The subsequent fire recovery operation (steps S326 to S342) is the same as the above-described fire recovery operation (steps S219 to S235). When the commercial power supply 51 is restored, the power failure detector 52 invalidates the power failure detection signal (step S343). When the power failure detection signal is invalidated (step S344), the central management control device 10 interrupts the circuit breaker CB3. (Step S345), the power recovery is displayed on the terminal device 111 (Step S346). At this time, the central management control device 10 may cause the speaker 112 to generate an alarm sound. Thereafter, the central management control device 10 shifts the mode to the cutoff mode (at power recovery) by logical operation processing (step S347). At this time, the centralized management apparatus 10 may cause the speaker 112 to generate an alarm sound. Thereafter, the operation in the blocking mode (steps S348 to S353) is the same as the operation in the blocking mode described above (steps S108 to S113). The subsequent power recovery operation (steps S354 to S367) is the same as the above-described power recovery operation (steps S178 to S191).

  According to the above operation, the power supply system determines an appropriate mode based on the state of the building fire, the commercial power supply 51, the self power supply 54, the circuit breakers CB1, CB2, CB3, etc. Can be controlled. The administrator can check the state and mode of the power supply system from the display on the terminal device 111, and can input to the power supply system by operating the terminal device 111.
