Description

  The present invention relates to an information processing system, an information processing apparatus, and a power consumption suppression support method that support power consumption suppression, and in particular, demand for opening a predetermined switch to prevent overload operation of a power transmission facility. The present invention relates to an information processing system, an information processing apparatus, and a power consumption suppression support method that support power consumption suppression that can surely know that a switch has been opened in response to a request at home.

  In recent years, with the widespread use of air conditioners and various IT devices, power consumption in general households has increased along with conventional large-volume consumers such as manufacturers. For example, in order to cope with the peak of power consumption such as in the afternoon in summer, the rated current is determined for power transmission facilities, power transmission and distribution lines and transformers for supplying power from the power plant to the end users. Therefore, although planned and designed, when the temperature rises extremely, the demand for electric power exceeding the forecast is generated, and it is often forced to operate under a current condition exceeding the rated current, so-called overload operation. Naturally, the power transmission facility is designed with a considerable safety factor in mind.However, overloading over a long period of time will cause adverse effects such as deterioration of the characteristics of the power transmission facility. It is necessary to deal with it so that it does not occur as much as possible.

  In addition, the power demand exceeded the power supply when the power supply temporarily declined due to some event at the power plant, etc., or when the temperature increased drastically in summer and the demand increased rapidly. In some cases, it may lead to a large-scale power outage.

  Conventionally, from the viewpoint of avoiding such a situation, a supply contract is made with a specific large customer such as a manufacturer to reduce the amount of power consumption that is negotiated in advance according to a request from the power company when the power demand increases. Measures are taken, but in the situation where power consumption in small consumers such as ordinary households is growing as described above, we request that those consumers finely control power consumption, There is a need for measures to avoid inconveniences such as overload operation and temporary stop of power supply.

For example, in Patent Document 1, a power provider and a general power consumer are connected via a transmission line and a communication line in order to realize a wide-area power demand control system for general consumers. A configuration is disclosed in which when a power consumption amount in a specific area managed by a power source exceeds a predetermined threshold, a power saving request is transmitted from a power company to a power consumer via a communication line in a simultaneous broadcast.
JP 2002-345177 A

  However, in the configuration proposed in this document, general consumers who are subject to a request for reducing power consumption can be requested all at once by telephone talk or e-mail, but each general consumer responds to the request. However, it was impossible to know whether or not the load device such as an air conditioner was actually stopped, and there was a problem that it was difficult to estimate the effect on the request.

  The present invention has been made to solve the above and other problems, and in response to a request from a customer who has requested the opening of a predetermined switch to prevent overload operation of a power transmission facility. It is an object of the present invention to provide an information processing system, an information processing apparatus, and a power consumption suppression support method that support power consumption suppression that can surely know that a switch has been opened.

  In order to achieve the above object, one aspect of the present invention is an information processing system for suppressing power consumption in a consumer in order to prevent overload operation of a power transmission facility, provided in the consumer A switch operation detection unit that detects the opening / closing operation of the predetermined switch, and a switch operation detection information reception that receives the information indicating the opening operation or the closing operation of the switch output from the switch operation detection unit And an overload state information receiving unit for receiving overload state information including distribution system information indicating a distribution system in which an overload state occurs, The overload state information receiving unit, comprising: a suppression request target customer specifying unit for specifying a consumer that is a target for requesting suppression of power consumption based on the distribution system information included in the overload state information. Is said overload When the state information is received, after notifying the suppression request message to the consumer specified by the suppression request target consumer specifying unit, the switch operation detection unit of the predetermined switch in the consumer An opening operation is detected and notified to the switch operation detection information receiving unit.

  According to the information processing system according to one aspect of the present invention, in a consumer who has requested opening of a predetermined switch to prevent overload operation of a power transmission facility, the switch is actually opened according to the request. I can know for sure.

Hereinafter, the present invention will be described in accordance with an embodiment thereof with reference to the accompanying drawings.

As shown in FIG.

  In the embodiment of FIG. 1, a branch line from a high-voltage distribution line 200 constituting a part of a distribution system from a power plant (not shown) is installed in a customer's house 300 as a low-voltage distribution line 220 via a pole transformer 210. It is connected to the watt hour meter 260. A PLC master station modem 230 that provides a master station function of power line communications (hereinafter referred to as “PLC”) is interposed between the pole transformer 210 and the watt hour meter 260 of the customer's home 300. ing.

  The PLC master station modem 230 is connected to the communication network N through a communication line 240 such as an optical fiber line. The PLC master station modem 230 cuts off the low-frequency power current between the communication line 240 and the communication network N and the low-voltage distribution line 220 drawn into the customer's house 300 via the watt-hour meter 260. In addition, it has a function to enable transmission and reception of high-frequency PLC communication signals. That is, the PLC master station modem 230 is installed, so that the low-voltage distribution line 220 on the downstream side can be used as a communication line of an electrical device equipped with a PLC slave station modem (not shown). It has become.

  The communication network N is a dedicated network such as an intranet, or can be the Internet under the premise of introducing appropriate security measures such as encryption for data to be transmitted and received.

  The low voltage distribution line 220 from the watt-hour meter 260 in the customer's house 300 is connected to the switchboard 270, is branched to a plurality of breakers B1 and B2, and is further wired in the house to supply power to a load device (not shown). As a power source to be supplied, an outlet is provided at an appropriate place in the customer's house 300. In addition, although illustration is abbreviate | omitted, the current limiter and the earth-leakage circuit breaker are provided in the switchboard 270 as usual. Of course, any number of breakers as switches can be installed.

  In the case of the present embodiment, an open / close sensor S that is a switch operation detector for detecting the open / close operation of the breaker B1 is provided in the vicinity of one breaker B1 in the switchboard 270. As the sensor S, for example, a non-contact sensor called a proximity switch that detects the presence of an object in the vicinity may be used to detect the opening / closing operation of the breaker lever, or the breaker itself. In addition, a structure in which a contact for repeating the open / close state of the breaker is provided may be used.

  The open / close sensor S is connected to a PLC communication line formed by the low voltage distribution line 220 in the house via a PLC slave station modem (not shown), and an open circuit detection signal as a result of detecting the open / close operation of the breaker B1; A closed circuit detection signal is transmitted to the management computer 100 (to be described later) over the network N via the PLC slave station modem, the PLC master station modem 230, and the communication line 240.

  In the present embodiment, the breaker B1 in which the open / close sensor S is installed opens the circuit when a request for suppressing power consumption is received from the power company by a prior contract between the customer's house 300 and the power company. It is a breaker that has been negotiated. In this case, as the breaker B1, a load device, such as an electric water heater or an air conditioner, which consumes a relatively large amount of power but has no trouble even if it is not always turned on, is connected to the downstream wiring. Select what you have. By doing so, when the breaker B1 is opened in response to a request for suppressing power consumption, a greater effect of suppressing power consumption can be expected.

  In this embodiment, the breaker B1 is attached with a configuration that can be closed by a remote operation through the communication network N. The user of the customer's home 300 is manually restored by a control signal from the management computer 100 described later. Even if it is not, it can be closed by remote control. In addition, the said structure does not necessarily exclude the structure which the user of the consumer's house 300 closes breaker B1 manually. In addition to the closed circuit of the breaker B1, it is also possible to employ a configuration in which both the opening and closing operations can be controlled from the management computer 100.

  A telephone 280 is also installed in the customer's house 300, and as will be described later, this is a receiver that receives a power consumption suppression request message from the management computer 100 and a suppression cancellation message for canceling the suppression. Function. This telephone 280 is connected to the management computer 100 via a telephone line 250. The telephone 280 may be connected to the communication network N as a network telephone using VoIP. Alternatively, a personal computer may be installed in place of the telephone 280, connected to the communication network N, and a suppression request message, a suppression release message, etc. from the management computer 100 may be received by e-mail or the like.

  A management computer 100 is connected to the communication network N. The management computer 100 has a configuration as a server computer that provides the functions of the system 1 according to the present embodiment. That is, a power consumption suppression request or suppression cancellation message is transmitted to the customer's home 300 through the communication network N and the PLC communication line (the entity is the low-voltage distribution line 220 drawn into the home as described above). Further, an open circuit signal or a closed circuit signal indicating the open / close operation of the breaker B1 detected by the open / close sensor S is received via the PLC communication line and the communication network N, and based on the actual open / close operation state of the breaker B1 in each customer house 300. To calculate the electricity charge.

Next, the management computer 100 will be described in more detail.
FIG. 2 is a diagram illustrating a hardware configuration of the management computer 100 as an information processing apparatus used in the system 1 of the present embodiment.

  The management computer 100 has a configuration as a general computer having a network communication function. For example, the CPU 102, the memory 104, the storage device 106, the recording medium reading device 108, the communication interface 110, the input device 112, and the output device. 114.

  The storage device 106 stores a program for executing the power consumption suppression request processing according to the system of the present embodiment, fixed data that is repeatedly used, and the like. The program stored in the storage device 106 is sequentially read out to the memory 104, and the CPU 102 executes the program read out to the memory 104. Here, the storage device 106 is, for example, a hard disk drive. The recording medium reading device 108 can read a program and data recorded on a recording medium 116 such as a CD-ROM and store it in the storage device 106.

  The communication interface 110 transmits and receives data to and from other computers via a network formed by the Internet, a LAN, a dedicated line, or the like. The other computer is, for example, a computer (not shown) that monitors power consumption in the distribution system and controls the amount of power supplied. The input device 112 includes a keyboard and a mouse. The output device 114 includes a display and a printer.

  FIG. 3 is a functional block diagram of the management computer 100 according to the present embodiment. The functions shown here are realized by reading and executing each functional block included in the power consumption suppression request program according to the present embodiment by the CPU 102 and the memory 104 on the hardware shown in FIG. The The I / O interface 118 manages input / output of data processed by these functional blocks.

  The overload state information receiving unit 120 receives data related to occurrence or cancellation of an overload operation state in a specific power distribution system from another computer that controls power supply and demand. In addition to responding to overload operating conditions that occur as a result of an increase in power consumption at consumers, a temporary decline in power supply occurs due to some event occurring at a power plant, etc. Therefore, it is necessary to reduce power consumption in the grid connected to the power plant. The overload state information in the present embodiment includes information received when it is necessary to suppress power consumption for such reasons. The configuration of the data representing the overload state information may be defined in any way according to the system specifications, but in general, a flag indicating a power consumption suppression request or suppression cancellation event and the suppression request or It is conceivable to include an ID or the like that identifies a power distribution system that is a target of suppression cancellation.

  The suppression request target customer identification unit 122 (hereinafter abbreviated as “customer identification unit 122”) transmits a suppression request message or a suppression release message based on the overload state information from the overload state information reception unit 120. The customer's house 300 to be targeted is specified. As shown in the figure, the management computer 100 according to the present embodiment includes a customer database 124 in which individual information such as a customer's telephone number, address, e-mail address, and ID of a connected distribution system is registered. Therefore, for example, the request destination telephone number or e-mail address of the corresponding customer is extracted from the customer database 124 by the distribution system ID that is the target of the suppression request received from the overload state information receiving unit 120. Can be configured.

  Or it is good also as a structure which does not provide the customer database 124, and in that case, in the overload status information which the overload status information receiving part 120 receives from another computer, the telephone number of the target consumer in advance, electronic An e-mail address or the like may be stored so that the customer specifying unit 122 that has received the overload state information can extract a telephone number or an e-mail address that is a transmission destination of the suppression request message or the like. Good.

  The suppression request cancellation transmission unit 126 sends a power consumption suppression request message or suppression cancellation message to the telephone number or email address of the customer's house 300 specified by the customer specification unit 122 via a telephone line or a communication line. Alternatively, it is transmitted as data or text data. The suppression request release transmission unit 126 also has a general function as an auto dialer or mailer software for transmitting a signal to the telephone number or e-mail address of the customer's house 300.

  The breaker operation control unit 128 receives the notification that the suppression release message has been transmitted from the suppression request cancellation transmission unit 126 to the customer's home 300, and after a predetermined time, the designated breaker installed in the customer's home 300 A closing control signal is transmitted to B1. The breaker operation control unit 128 can also be configured to transmit a signal for controlling the opening / closing operation of the designated breaker B1.

  The breaker open / close operation receiving unit 130 uses the open / close sensor S to open / close the breaker B1 that is determined to be opened when a power consumption control request message is received from the operator at the time of a prior power supply contract. Receive the detection results. Thereby, the electric power company can know that the designated breaker B1 is actually opened in the requested customer's house 300 in response to the suppression request.

  The power consumption amount receiving unit 132 receives the detected power amount data from the watt hour meter 260 provided in the customer's home 300 through the PLC communication line (low voltage distribution line 220), the communication line 240, and the communication network N. The received power amount data is used as basic data for charge calculation in the discount charge calculation unit 134 described below as required.

  The discount charge calculation unit 134 monitors the opening operation detection received from the breaker opening / closing operation receiving unit 130 for each customer's house 300 that is the target of the power consumption suppression request message transmission, and a signal indicating the opening operation is input. Then, according to the prior contract with the customer's house 300, the discount rate for the power charge is calculated as set forth in the contract. For example, when a specified breaker opening operation of the customer's house 300 is detected as described above, a certain amount of charge discount is executed based only on the condition. Can do.

  Alternatively, it is possible to count the time from when the specified breaker is opened until the suppression request is released until the breaker is closed, and to change the discount rate according to the length. Furthermore, the power consumption detected by the watt hour meter before opening the specified breaker can be compared with the power consumption after the opening, and the discount rate can be changed according to the substantial power consumption suppression effect.

  Next, the flow of processing executed by the management computer 100 of the power consumption suppression request system 1 in this embodiment will be described with reference to the flowchart of FIG.

  When the system of the management computer 100 is activated, the overload state information receiving unit 120 waits until it receives overload state information from another computer that controls and manages power supply and demand (No in S400).

  When the overload state information is received (S400, Yes), the overload state information receiving unit 120 sends the information to the consumer specifying unit 122, and the consumer specifying unit 122 includes the received overload state information. A list of consumers to which a suppression request message is transmitted is acquired from information such as an ID for specifying a distribution system that is a suppression request target and a customer record registered in the customer database 124 ( S402).

  As described above, at this time, information specifying the target consumer may be included in the overload state information data received from another computer. A configuration in which the house database 124 is not provided may be employed.

  Next, based on the request target customer list received from the consumer specifying unit 122, the suppression request cancellation transmission unit 126 sequentially transmits the power consumption suppression request message to the telephone number of the target consumer (S404). . When transmitting by telephone, specifically, the telephone numbers of the listed customers are sequentially called by an auto dialer or the like, and after off-hook is detected, it is generated in advance and stored in the storage device 106. The voice of the request message is transmitted to the telephone line 250. When it is detected that the target telephone number is busy, it can be configured to make a call again after a predetermined time.

  When an e-mail is transmitted instead of a telephone, it is difficult to detect a reception confirmation from the transmission destination, and therefore it can be assumed that the suppression request message is transmitted upon completion of the e-mail transmission.

  With respect to the destination consumer's house 300 that has transmitted the suppression request message, the open / close sensor S detects the opening of the breaker B1 designated for the consumer's house 300, and the breaker open / close operation receiving unit 128 opens from each customer's house 300. Wait until the operation information is received (S406, No). When the opening operation information is received (S406, Yes), the opening time count of the designated breaker B1 is started for the customer's house 300 (S408).

  In addition, it is determined that the customer's house 300 that cannot receive the opening operation information even after the elapse of a predetermined time since the suppression request message is transmitted is determined not to respond to the suppression request, and is excluded from the discount charge application target. Can be.

  Next, the overload state information receiving unit 120 waits for reception of overload state information indicating release of suppression based on overload operation state cancellation or the like from another computer (S410, No). If the information which shows this suppression cancellation is received (S410, Yes), the information will be transmitted to the suppression request cancellation | release transmission part 126, and the received suppression request cancellation | release transmission part 126 will sequentially transmit the power consumption suppression suppression message to the target consumer's house 300. Is transmitted by telephone or the like as in S404.

  Next, after transmitting the power consumption suppression release message, the breaker operation control unit 128 transmits a control signal for closing the designated breaker B1, which is opened, thereby closing the breaker B1 (S414).

  As for the destination customer's house 300 that has transmitted the release message, the open / close sensor S installed in the vicinity of the designated breaker B1 of the customer's house 300 detects that the designated breaker B1 that has been opened has been closed, and the information is received. The breaker opening / closing operation receiving unit 130 is on standby (S416, No).

  When the breaker opening / closing operation receiving unit 130 receives the closing operation information indicating that the closing operation of the designated breaker B1 of the customer's house 300 has been detected (S416, Yes), it is determined that the response to the suppression request of the customer's house 300 has been completed. The circuit opening time count of the breaker B1 is terminated, and the circuit opening time data is transmitted to the discount fee calculation unit 134 (S418).

  The discount fee calculation unit 134 calculates a discount fee defined in advance by a contract with the customer's home 300 based on the open circuit time data received for the customer's home 300 (S420), and ends the flow.

  As described above, according to the power consumption suppression request system according to an embodiment of the present invention, in a consumer who has requested opening of a predetermined switch to prevent overload operation of a power transmission facility, It is possible to reliably know that the switch has been opened upon request.

  Further comprising a consumer database storing unique information about the consumer, including information about the distribution system to which the consumer is connected and information indicating whether or not the power consumption is to be restrained. If the target consumer identifying unit extracts a consumer to be requested for suppression of power consumption from the consumer database based on the distribution system information included in the received overload state information, When an overload operation of a facility occurs, it is possible to immediately extract a consumer who should be a target of a power consumption suppression request.

  When the overload state information receiving unit receives overload state elimination information indicating the elimination of the overload state, the customer who has notified the suppression request is notified of a suppression release message, and then the predetermined switch is closed. If this is detected, it is possible to notify the consumer who requested the suppression without delay when the overload condition is resolved, and to minimize the inconvenience regarding the use of power in the consumer.

  When receiving information indicating that the opening operation of the switch of the consumer requested to be suppressed is received from the switch operation detection unit, a discount charge calculation unit that calculates a power charge discount amount for the corresponding consumer is provided. If this is the case, it is possible to provide a discount for the electricity rate only to customers who actually respond to the request to reduce power consumption, ensuring fairness with customers who did not respond to the request. .

  The discount fee calculation unit receives information on elapsed time from the time when the switch operation detection unit detects the opening operation of the predetermined switch to the detection of the closing operation, and the corresponding demand according to the elapsed time If the power charge discount amount for the house is calculated, it is possible to distribute a charge discount privilege to the consumer according to the time according to the request for suppressing the power consumption.

  The discount rate calculation unit is configured to be connectable to a consumer watt-hour meter via a communication line and configured to acquire a consumer's power consumption, and the switch operation detection unit opens the predetermined switch Comparing the power consumption before detecting the operation and the power consumption after the opening operation of the predetermined switch, and calculating the power charge discount amount for the corresponding consumer according to the difference, For customers who actually respond to the request for suppressing the power consumption, a privilege for discounting the price can be distributed to the customer according to the power suppression effect.
