  The present invention relates to a supply power control method capable of flattening the peak of power consumed by each door so as not to exceed the supply capacity of a commercial power source, and the distribution board.

There is a method of performing a planned power outage (hereinafter referred to as “planned power outage”) so that the peak of power consumed by each house does not exceed the supply capacity of the commercial power source. A planned power outage enters a predetermined area for a predetermined time when it is predicted that the supply amount of the commercial power source will not be able to catch up with the total power consumed by each house in the power supply area of the commercial power source. The power supply is stopped, and a power failure area and power failure time are designated in advance from the commercial power source supplier side, and the power supply is systematically stopped.
As an example of reducing the power consumption, conventionally, when a current more than the contract current is consumed, the electric circuit is interrupted by the ampere breaker of the distribution board.

EMBODIMENT OF THE INVENTION Below, the form for implementing this invention is demonstrated using drawing.
● [Power supply path from commercial power source 1 to each of the houses H1 to H4 and communication path from the management device 2 (FIG. 1)]
As shown in FIG. 1, power is supplied from the commercial power source 1 to the doors H1 to H4 via power supply lines 90A and 90B.
A distribution board 20 is provided in each of the doors H1 to H4, and the power supply lines 90A and 90B and the distribution board 20 are connected via the power supply lines 91A to 94A. Wiring is connected to the outlet, etc., and an electric load such as lighting equipment or air conditioning equipment is connected to the outlet, and power supplied from the commercial power source 1 is consumed.
In addition, the management device 2 that is a server on the power supply side or the like distributes the distribution board 20 connected to the power supply lines 90A and 90B by so-called power line communication on a path indicated by a dotted line that uses the power supply line as a communication line.

In addition, a signal can be transmitted to the distribution board 20 connected to the wireless communication line via the base station 4A. As described above, there are various communication methods from the management device 2 to the distribution board 20, and the communication method is not particularly limited. Further, it is sufficient that at least a signal can be transmitted from the management device 2 to the distribution board 20, and transmission of the signal from the distribution board 20 to the management device 2 may or may not be performed.

[Configuration of distribution board 20 and example of wiring to each room 101-202 (FIG. 2), configuration of receiving means 30 and control means 40 (FIG. 3)]
Next, the structure of the distribution board 20 of each door, the wiring from the distribution board 20 to each room, etc. are demonstrated using FIG.
The distribution board 20 is provided with an amper breaker 21, a main breaker 22, branch breakers 23A to 23F, a receiving means 30, a control means 40, and forced cutoff means 50A to 50F. The electric power supplied from the commercial power source 1 passes through the power breaker 21 from the power supply line 91A, then through the main breaker 22, and further through the branch breakers 23A-23F in each of the rooms 101-202. The outlets C11 to C26 are supplied.

The ampere breaker 21 is a breaker that interrupts the electric circuit when the current supplied from the power supply line 91A exceeds the contract current with the power supply company. As a result, the current exceeding the contract current cannot be consumed in each house.
The main breaker 22 is a breaker for preventing an electric shock accident or damage to equipment, and is a breaker for cutting off an electric circuit when a leakage or a ground fault is detected.
The branch breakers 23A to 23F are breakers that branch the power supplied from the main breaker 22 into a plurality of pieces, and wiring (electric circuit) is connected from each branch breaker to each outlet in each room.
For example, in the case of FIG. 2, each outlet is associated with each branch breaker according to a priority rank described later.
For example, the branch breaker 23A is a breaker corresponding to the priority rank A described later, and is connected to the wiring 24A of the communication device outlets C21 and C24 in the rooms 201 to 202 on the second floor. Connect power outlets that are extremely troublesome in daily life, such as TVs, radios, telephones, Internet connection devices, and refrigerators (refrigerators are not communication devices but priority rank A is preferred as important devices) to this outlet. Are preferably used.
For example, the branch breaker 23B is a breaker corresponding to a priority rank B described later, and is connected to the wirings 24B of the general outlets C23 and C26 of the rooms 201 to 202 on the second floor. It is preferable to use a device that can be tolerated even if power supply is stopped, for example, lighting, cooking utensils, washing machines, vacuum cleaners, and music playback devices connected to this outlet.
For example, the branch breaker 23C is a breaker corresponding to a priority rank C described later, and is connected to the air conditioner outlets C22 and C25 of the rooms 201 to 202 on the second floor. For example, it is preferable to use an air conditioner or heater that is not inconvenienced immediately after being stopped, connected to this outlet. Note that the illumination may also have a priority rank C.
For example, the branch breaker 23D is a breaker corresponding to a priority rank A to be described later, and is connected to the wiring 24D of the communication device outlets C11, C14, C17 of the rooms 101 to 103 on the first floor.
For example, the branch breaker 23E is a breaker corresponding to the priority rank B described later, and is connected to the wirings 24E of the general outlets C13, C16, C19 of the rooms 101 to 103 on the first floor.
For example, the branch breaker 23F is a breaker corresponding to the priority rank C described later, and is connected to the wiring 24F of the air conditioner outlets C12, C15, C18 of the rooms 101 to 103 on the first floor.
In addition, it is more preferable to specify priority ranks “A” to “C” in the outlets of each room because the user can connect any electrical device to the outlet of the priority rank desired.

  Each of the forcible shut-off means 50A to 50F is provided in association with each of the branch breakers 23A to 23F, and based on a control signal from the control means 40, the corresponding branch breaker can be forcibly shut off. . In the example of FIG. 2, each of the branch breakers is provided with a forced cutoff means, but the forced cutoff means is provided in association with at least one of the main breaker and the branch breaker, and is associated with the breaker. As long as it can be forcibly blocked. Moreover, not only the interruption | blocking but based on the control signal from the control means 40 may be comprised so that a corresponding breaker can be reset from an interruption | blocking state.

The receiving unit 30 receives a signal from the management device 2 on the power supply side, and outputs the received signal to the control unit 40. As shown in FIG. 3, when a signal from the management device 2 is received by power line communication, the signal from the management device 2 is input from the power line 91 </ b> B to the processing means 31 such as a CPU via the power line circuit 32. . When a signal from the management device 2 is received by ADSL or an optical cable, the signal from the management device 2 is input to the processing means 31 from the cable 3B via the cable circuit 33. When a signal from the management device 2 is received by wireless communication, the signal from the management device 2 is input to the processing means 31 via the antenna 4B and the wireless communication circuit 34. The receiving means 30 may be equipped with necessary ones among the power line circuit 32, the cable circuit 33, the antenna 4B, and the wireless communication circuit 34 according to the communication method to be used.
The processing unit 31 is, for example, a CPU, and outputs a signal received via the power line circuit 32, the cable circuit 33, or the wireless communication circuit 34 to the control unit 40.
The receiving means 30 is provided with a storage means 35 in which a program for controlling the operation of the processing means 31 is stored.

The control means 40 receives the signal transmitted from the management device 2 via the receiving means 30, and specifies the breaker to be controlled from the main breaker 22 and the branch breakers 23A to 23F based on the received signal. Then, a control signal is output to the forced cutoff means associated with the specified breaker to forcibly cut off the electric circuit.
As shown in FIG. 3, the control means 40 includes a processing means 41, a storage means 43, notification means 44S, 44A to 44D, and the like.
The processing means 41 is a CPU, for example, and outputs a control signal to the forced cutoff means 50A to 50F based on a signal received via the receiving means 30, and outputs a control signal to the notification means 44S and 44A to 44D.
The storage means 43 stores a program for controlling the operation of the processing means 41, distribution board information for specifying the distribution board 20, and the like. The distribution board information will be described later.
The notification means 44S, 44A to 44C are display means such as LEDs, and the notification means 44D is sound output means such as speakers.

[Processing procedure of control means 40 (FIG. 4)]
Next, the processing procedure of the control means 40 will be described using the flowchart of FIG.
When it is predicted that the power consumption of each household will increase and eventually exceed the supply capacity, the power supply company transmits a transmission signal from the management device 2 so as not to exceed the supply capacity.
The control means 40 of the distribution board 20 of each house determines whether the transmission signal from the management apparatus 2 was received in step S10. When the transmission signal is received (Yes), the process proceeds to Step S20, and when the transmission signal is not received (No), the process returns to Step S10.

When the process proceeds to step S20, the control means 40 determines whether the distribution board 20 provided with the control means 40 is a control target of the received transmission signal based on the distribution board selection signal included in the transmission signal. Determine whether or not.
Here, the contractor information 2Z shown in FIG. 5A, the distribution board information 41Z shown in FIG. 5B, and the transmission signal S0 shown in FIG. 5C will be described.
The contractor information 2Z shown in FIG. 5A is stored in the management apparatus 2, and the contractor information 2Z includes a distribution board according to an ID for identifying each distribution board and a priority of power cut-off. User type information (ie, contractors) grouped, area information for power shutdown by region, address of contractor contracted with power supply company, contractor name, contractor contact information, remarks, etc. Has been. In the example of FIG. 5 (A), the user type information “10” is assigned to a hospital that has an influence on human life and should not be forcibly cut off power. “90” is assigned to the user type information for the personal residence estimated to be allowed.
5B is stored in the storage means 43 of the control means 40. The distribution board information 41Z shown in FIG. The distribution board information 41Z includes an ID assigned to the distribution board, user type information of a contractor of the distribution board, area information, breaker identification information assigned to each of the main breaker and branch breaker, and priority rank information. Remarks etc. are registered. In the example shown in FIG. 5B, the priority rank information is set to one of ranks S, A, B, and C for all of the main breaker and the plurality of branch breakers. In this case, the priority rank indicates the rank of priority on the contractor side of the distribution board, and is set so that the priority increases in the order of C <B <A <S. The priority rank C is a rank with the lowest priority, and is associated with a breaker that may be shut off first, for example, a branch breaker that supplies power to an outlet for an air conditioner. In the priority rank S having the highest priority, a main breaker that is blocked from supplying all electric power is associated. In addition, it is preferable to assign a priority rank A to a device related to human life such as a medical device or a communication device such as a television or a radio.
The ID for identifying each distribution board is, for example, a MAC address or an IPv6 address.
As shown in FIG. 5C, the transmission signal S0 transmitted from the management device 2 includes a distribution board selection signal S1 (in this case, user type information) for selecting the target distribution board, A shut-off / return signal S2 (corresponding to a forced shut-off signal) that is a shut-off command or a return command, and a breaker selection signal S3 (in this case, priority rank information) for selecting a breaker to be cut off in the target distribution board, It is included.
In the following description, an example in which the user type information shown in FIG. 5 is used as the distribution board selection signal S1 included in the transmission signal S0 will be described, but an ID (for example, a distribution board) is used instead of the user type information. A unique MAC address or IPv6 address) may be used.
In step S20, the control means 40 collates the distribution board selection signal included in the received transmission signal with the user type information of the distribution board information 41Z stored in the storage means 43, and the collation matches. If yes (Yes), the process proceeds to step S110. If they do not match (No), the process ends and the process returns to step S10.

When the process proceeds to step S110, the control unit 40 determines whether or not the cutoff / return signal included in the received transmission signal is a signal for instructing cutoff. If it is a signal for instructing blocking (Yes), the process proceeds to step S120, and if it is not a signal for instructing blocking (No), the process proceeds to step S210.
When the process proceeds to step S120, the control means 40 determines whether or not the breaker selection signal included in the received transmission signal is the priority rank S. If it is priority rank S (Yes), the process proceeds to step S121. If it is not priority rank S (No), the process proceeds to step S130.
When the processing proceeds to step S121, the control means 40 performs notification (for example, a notice) corresponding to the priority rank S, performs notification for a certain time, and then proceeds to step S122. For example, the notification means 44D outputs a voice message “I will shut down the main breaker in xx seconds from now” and blinks or lights the notification means 44S associated with the priority rank S. Note that the audio information may be stored in the storage unit 43 in association with the priority rank, or may be included in the transmission signal.
In step S122, the control means 40 outputs a control signal to the breaker forcible shut-off means associated with the priority rank S in the distribution board information 41Z, forcibly shuts down the target breaker, and performs processing. End and return to step S10. Since the power of the control means 40 is supplied from the upstream side of the main breaker 22, the control means 40 can operate even when the main breaker 22 is shut off. In this case, the forced breaker 50S corresponding to the main breaker 22 associated with the priority rank S is driven to block the main breaker 22.

When the process proceeds to step S130, the control means 40 determines whether or not the breaker selection signal included in the received transmission signal is the priority rank A. When it is priority rank A (Yes), the process proceeds to step S131, and when it is not priority rank A (No), the process proceeds to step S140.
When the process proceeds to step S131, the control means 40 performs notification (for example, a notice) corresponding to the priority rank A, performs notification for a certain time, and then proceeds to step S132. For example, the notification means 44D outputs a voice message “I will cut off the priority rank A breaker xx seconds from now”, and blinks or lights the notification means 44A associated with the priority rank A. Note that the audio information may be stored in the storage unit 43 in association with the priority rank, or may be included in the transmission signal.
In step S132, the control means 40 forcibly shuts off the target breaker by outputting a control signal to the forced breaker means of the breaker associated with the priority rank A in the distribution board information 41Z. End and return to step S10. In this case, the forcible shut-off means 50A and 50D corresponding to the branch breakers 23A and 23D associated with the priority rank A are driven to shut off the branch breakers 23A and 23D.

When the process proceeds to step S140, the control means 40 determines whether or not the breaker selection signal included in the received transmission signal is the priority rank B. When it is priority rank B (Yes), the process proceeds to step S141, and when it is not priority rank B (No), the process proceeds to step S151.
Hereinafter, step S141 and step S142 are notification and blocking corresponding to priority rank B, and step S151 and step S152 are notification and blocking corresponding to priority rank C, and notification and blocking corresponding to priority rank A described above. Since it is the same as the process of a certain step S131, S132, description is abbreviate | omitted.

When the process proceeds to step S210, the control means 40 determines whether or not the cutoff / return signal included in the received transmission signal is a signal for instructing the return. If the signal is an instruction to return (Yes), the process proceeds to step S220, and if the signal is not an instruction to return (No), the process proceeds to step S310.
When the processing proceeds to step S220, the control means 40 determines whether or not the breaker selection signal included in the received transmission signal is the priority rank S. When it is priority rank S (Yes), it progresses to step S221, and when it is not priority rank S (No), it progresses to step S230.
When the processing proceeds to step S221, the control means 40 performs notification (for example, a notice) corresponding to the priority rank S, performs notification for a certain time, and then proceeds to step S222. For example, the notifying unit 44D outputs a voice message “The main breaker will be restored in xx seconds from now”, and the notifying unit 44S associated with the priority rank S is blinked or lit. Note that the audio information may be stored in the storage unit 43 in association with the priority rank, or may be included in the transmission signal.
In step S222, the control means 40 outputs a control signal to the forced breaker means of the breaker associated with the priority rank S in the distribution board information 41Z to forcibly return the target breaker to perform the processing. End and return to step S10. Since the power of the control means 40 is supplied from the upstream side of the main breaker 22, the control means 40 can operate even when the main breaker 22 is shut off. In this case, the forced breaker 50S corresponding to the main breaker 22 associated with the priority rank S is driven to return the main breaker 22.

When the process proceeds to step S230, the control means 40 determines whether or not the breaker selection signal included in the received transmission signal is the priority rank A. When it is priority rank A (Yes), the process proceeds to step S231, and when it is not priority rank A (No), the process proceeds to step S240.
When the processing proceeds to step S231, the control means 40 performs notification (for example, a notice) corresponding to the priority rank A, performs notification for a certain time, and then proceeds to step S232. For example, the notification means 44D outputs a voice message “Returning the priority rank A breaker xx seconds from now”, and the notification means 44A blinks or lights up. Note that the audio information may be stored in the storage unit 43 in association with the priority rank, or may be included in the transmission signal.
In step S232, the control means 40 outputs a control signal to the forced breaker means of the breaker associated with the priority rank A in the distribution board information 41Z to forcibly return the target breaker to perform the processing. End and return to step S10. In this case, the forcible shut-off means 50A and 50D corresponding to the branch breakers 23A and 23D associated with the priority rank A are driven to return the branch breakers 23A and 23D.

When the process proceeds to step S240, the control unit 40 determines whether or not the breaker selection signal included in the received transmission signal is the priority rank B. If it is priority rank B (Yes), the process proceeds to step S241. If it is not priority rank B (No), the process proceeds to step S251.
Hereinafter, step S241 and step S242 are notification and return corresponding to priority rank B, and step S251 and step S252 are notification and return corresponding to priority rank C, and notification and return corresponding to priority rank A described above. Since it is the same as the process of a certain step S231, S232, description is abbreviate | omitted.
Further, when the process proceeds to step S310, it is a case where the cutoff / return signal included in the received transmission signal is neither a cutoff instruction nor a return instruction. For example, the transmission signal from the power supply side is used to contact each house. A voice such as a prior notice of a planned power outage including voice information is output from the notification means 44D, the process is terminated, and the process returns to step S10.

In the present embodiment described above, an example has been described in which the forced breaker means 50S and 50A to 50F are provided in all of the main breaker 22 and the branch breakers 23A to 23F, but the main breaker 22 and the branch breakers 23A to 23F You may comprise so that a forced interruption | blocking means may be provided in at least one. Moreover, in order to avoid complete power failure, you may comprise so that the main breaker 22 may not be provided with the forced interruption | blocking means.
Moreover, although the example which selects the distribution board which cuts off (or resets) including a distribution board selection signal in a transmission signal was demonstrated, you may abbreviate | omit the distribution board selection signal and distribution board selection.
Further, although an example of processing that enables forcible interruption and return including a cutoff / return signal in the transmission signal has been described, the cutoff / return signal may be omitted and only interruption may be performed. In this case, the return is performed manually by the user. In addition, while the breaker is manually shut off, the target breaker is shut off again even if the user manually resets the breaker. However, the notification means 44S, 44A to 44D continuously notify and shuts off even if the breaker is returned. It is notified that it is returned to.
Further, although an example has been described in which priority rank information is set and a breaker to be blocked including a breaker selection signal in a transmission signal is selected, the breaker selection signal and the breaker selection may be omitted.
In addition, the transmission signal includes a regional signal corresponding to the area information, and the control means 40 collates the regional signal included in the transmission signal with the area information stored in the distribution board information 41Z. If they match, it may be configured to shut off or return.
In the description of the present embodiment, the example in which the interruption or the return is performed (after a certain time) at the timing when the transmission signal is received has been described. However, the control means 40 includes the time signal in the transmission signal. It is also possible to configure such that the time is cut, the block is automatically executed when the set cut-off time is reached, and is automatically returned when the set return time is reached.

If the distribution board and the power supply method described in this embodiment are used, the power consumption of each house can be forcibly reduced, so that it is necessary to make each house in some areas completely out of power. The peak of power consumption can be reduced more systematically and fairly.
In addition, it is possible to raise the awareness of participation in energy saving in each house.
In addition, the power supply company can flatten the peak of power consumption, so there is no need to urgently add power generation facilities according to the required power. I can go.
For example, when the total power consumption approaches the power generation amount upper limit, the power supply company transmits a transmission signal from the management device 2 so as to shut off the breaker of the priority rank C of the private house.
If the power consumption still approaches the power generation amount upper limit, a transmission signal is transmitted from the management apparatus 2 so as to shut off the breaker with the priority rank B of the private house.
Further, when the power consumption approaches the power generation amount upper limit, a transmission signal is transmitted from the management device 2 so as to shut off the breaker with the priority rank C of the public facility.
As described above, the power consumption can be reduced stepwise according to the overall power consumption situation.
In addition to assigning medical devices related to human life and communication devices such as televisions and radios to breakers of priority rank A, other devices related to human life, devices related to safety, devices related to economy, etc. It is preferable to assign to the breaker of A.
Although there is no need to classify clearly in terms of human life, safety, and economy, for example, as other equipment related to human life, various equipment in hospitals, water pumps in buildings and condominiums, toilets that drain water electrically, etc. Can be considered.
For example, as a device related to safety, a traffic light, an automatic lock of a building or a condominium, a security camera, etc. can be considered.
For example, as equipment related to the economy, various equipment such as ATMs of financial institutions, ticket gates of public transportation such as trains, equipment related to parking gates, and the like are conceivable.
The setting of the priority rank information (A, B, C) of each branch breaker may be configured so that the user can freely change it with a setting dial or the like.

The power supply control method and distribution board of the present invention are not limited to the appearance, configuration, structure, processing, display / output examples, etc. described in the present embodiment, and various types are possible without changing the gist of the present invention. It can be changed, added and deleted.
In the explanation of the present embodiment, it has been explained that it is possible to reduce power consumption more evenly for a so-called planned power outage. Is also possible.
In addition, the priority rank information has been described as an example in which four ranks of S, A, B, and C are set. However, the rank may be set more finely or may be reduced to three ranks. It can be changed.
The power supply company may measure the power consumption for each priority rank and change the charge for each rank. For example, the power consumption at the priority rank C can be promoted even if it is at a lower priority rank by making the charge cheaper than the power consumption at the priority rank A.
Further, the contractor information 2Z, the distribution board information 41Z, the transmission signal S0, and the like are not limited to the examples described in the present embodiment.
