Conventionally, a controller that controls home appliances connected to a customer's internal network acquires an electricity bill through the external network, and determines a time zone in which the power consumption of the home appliance is to be reduced based on the electricity bill. A technique has been proposed (see Japanese Patent Application Publication No. 2011-142753, hereinafter referred to as “Document 1”). In Document 1, the controller controls the operation of the home appliance in a time zone in which power consumption should be reduced, thereby reducing the amount of power consumed by the home appliance.

The second communication I / F unit 12 may exchange the management information directly with the equipment device 72, but usually exchanges the management information with the controller 70 that manages the equipment device 72, and the actual management of the equipment device 72 is performed by the controller. 70 is desirable. This type of controller 70 is called a HEMS (Home Energy Management System) controller, and can monitor and control the operating state of the equipment 72. When the link adapter 10 manages the facility device 72 such as a digital home appliance that does not communicate with the HEMS controller but can communicate with the communication device 73, the second communication I / F unit 12 includes the communication device 73. The management information may be transmitted to the facility device 72 through.

The presentation information is presented by the presentation device 71 and provides various information to the user. The method of presenting information by the presentation device 71 includes display on a screen included in the presentation device 71 and generation of sound by a speaker included in the presentation device 71.

The presentation device 71 may have only a presentation function, but it is preferable that operation is possible like an operation display device. In this case, the presentation device (operation display device) 71 can be used by the user who has recognized the information presented on the presentation device 71 for the purpose of changing the operating state of the equipment device 72. In this case, an instruction given from the user to the presentation device 71 is notified to the facility device 72 directly or via the controller 70. When the user uses a device capable of communicating with the communication device 73 such as a smartphone, a tablet terminal, a television receiver, or a personal computer as the presentation device 71, the second communication I / F unit 12 (distribution panel 30 ) May transmit the presentation information to the presentation device 71 through the communication device 73 as illustrated in FIG. 3.

Notification information is used to notify information to electric utilities. As illustrated in FIG. 3, the second communication I / F unit 12 (distribution panel 30) transmits the notification information to the management device 61 operated by the electric power company through the communication device 73.

The communication method (first communication method; for example, power line carrier communication) of the first communication I / F unit 11 is the same as the communication method (second communication method; for example, wireless communication) of the second communication I / F unit 12. May be different.

The processing unit 13 includes a device including a processor that executes a program as a main hardware element. A typical example of this type of device is a microcomputer having a memory. That is, the processing unit 13 includes a memory 131 for storing programs and data as shown in FIG. The processing unit 13 may be a CPU (Central Processing Unit) that requires a separate memory. That is, the cooperation adapter 10 may include a memory (not shown) provided separately from the processing unit 13.

The program and data necessary for the operation of the processing unit 13 are given through either the first communication I / F unit 11 or the second communication I / F unit 12. Alternatively, programs and data necessary for the operation of the processing unit 13 may be given through a storage medium 16 such as a memory card.

When the processing unit 13 acquires the program and data through the first communication I / F unit 11, the program and data are received from the electric power company through a route via the watt-hour meter 20. That is, the watt-hour meter 20 needs to communicate with a host device operated by an electric power company or the like through a telecommunication line NT which is a public network such as an Internet line, a CATV network, and a telephone network. This type of host device includes a management device 61 operated by an electric power company, a management device 62 operated by a service provider that is not an electric power company, and the like (see FIG. 3).

Here, the management device 62 operated by the service provider provides a service for performing energy management to the consumer. Further, the management device 62 provides a service for measuring the amount of power used by the consumer and notifying the electric utility, or a service for notifying the consumer of a demand response such as a power saving request from the electric utility. To do. In the example illustrated in FIG. 3, a communication path is configured so that the management device 61 operated by the electric power company communicates with the management device 62 operated by the service provider. The management device 62 communicates with the watt-hour meter 20 to perform remote meter reading of the power amount measured by the watt-hour meter 20, and also uses the watt-hour meter 20 for relaying information (so-called demand response). Information) to consumers. In the present embodiment, the information on the power saving request notified from the management device 62 is received by the link adapter 10 through the watt hour meter 20.

The management device 62 can also transfer the program and data to the link adapter 10 using the watt-hour meter 20 for relaying, in the same manner as the power saving request described above. Furthermore, since the watt-hour meter 20 can communicate with the linkage adapter 10, it is also possible to transmit information regarding the measured power to the linkage adapter 10. Therefore, the processing unit 13 can acquire a program and data from the management device 62 (or 61) through the first communication I / F unit 11 (and the watt-hour meter 20).

When the processing unit 13 acquires a program and data through the second communication I / F unit 12, the program and data are received from a support device (not shown) capable of communicating with the second communication I / F unit 12. Is transferred. The support device downloads the program and data through an electric communication line such as the Internet line, and causes the processing unit 13 to read the program and data through the second communication I / F unit 12. The support device may be a device that can communicate with both the second communication I / F unit 12 and the communication device 73 such as a personal computer, a smartphone, and a tablet terminal.

As shown in FIG. 1, the link adapter 10 includes a connection unit 15 that allows the storage unit 16 to be attached and detached so that the processing unit 13 obtains a program and data from the storage medium 16. You may have. The connection unit 15 includes a slot into which the memory card is inserted, and has a configuration in which contacts that are electrically connected to the electrodes of the memory card are disposed in the slot.

Here, it is desirable that the processing unit 13 reads the program and data stored in the storage medium 16 when the storage medium 16 is attached to the connection unit 15. That is, when the user inserts the storage medium 16 into the connection unit 15 and the processing unit 13 confirms the information stored in the storage medium 16 and determines that it can be read, The stored information may be read into the processing unit 13.

After the processing unit 13 reads the program and data, the storage medium 16 can be removed from the connection unit 15, so that a plurality of different coordination adapters 10 can read the program and data using one storage medium 16. Is possible.

Regardless of whether the processing unit 13 reads the program and data from the first communication I / F unit 11, the second communication I / F unit 12, or the storage medium 16, What is necessary is just to alert | report the completion | finish of reading.

For example, when the processing unit 13 needs to read a program and data, the processing unit 13 sends presentation information for requesting the program and data to the support apparatus through the second communication I / F unit 12. The support apparatus presents presentation information for requesting a program and data on a screen. When the support device receives an instruction to read the program and data from the user in response to the presentation information, the support device requests the program and data from the management device 62 through the telecommunication line. The management device 62 that has received the request sends the requested program and data to the processing unit 13 through the first communication I / F unit 11. Alternatively, the management device 62 that has received the request sends the requested program and data to the processing unit 13 through the support device and the second communication I / F unit 12. The processing unit 13 reads the received program and data and stores them in the memory 131. When the reading of the program and data is completed, the processing unit 13 transmits presentation information indicating that the reading is completed to the support apparatus.

The processing unit 13 has a function of generating output information using information acquired through at least one of the first communication I / F unit 11 and the second communication I / F unit 12 as input information. For example, the processing unit 13 generates output information based on information acquired from the watt-hour meter 20 through the first communication I / F unit 11. The output information generated by the processing unit 13 is transmitted from at least one of the first communication I / F unit 11 and the second communication I / F unit 12. For example, the output information generated by the processing unit 13 is output from the second communication I / F unit 12 to a device used by a consumer.

Note that the input information input to the processing unit 13 is not limited to information input through the first communication I / F unit 11 and the second communication I / F unit 12. Other input information input to the processing unit 13 will be described later. The output information output from the processing unit 13 will also be described later.

The first communication I / F unit 11, the second communication I / F unit 12, and the processing unit 13 are accommodated in the container 14.

Note that the measurement unit 33 may be configured to include only a current sensor, and the processing unit 13 may calculate power by providing the current value and the voltage value as input information to the linkage adapter 10. In this case, the information regarding the use of power for each load circuit 38 is a current value and a voltage value measured for each load circuit 38.

For example, the measurement unit 33 includes a sensor block 39 provided with a plurality of sensors 390 as shown in FIG. The sensor block 39 is formed in a rectangular plate shape, and a plurality of insertion holes 391 are provided in two rows along the longitudinal direction. A sensor 390 (Rogowski coil) is provided around each of the lower insertion holes 391 in FIG.

In the plurality of upper insertion holes 391 in FIG. 5, for example, a plurality of connection terminals of a conductive bar of a neutral electrode are respectively inserted, and in the plurality of lower insertion holes 391, for example, a first voltage electrode A plurality of connection terminals of the conductive bar are respectively inserted. The two terminals of the first terminal of each branch breaker 32 are respectively connected to the connection terminal of the neutral electrode conductive bar and the connection terminal of the first voltage electrode conductive bar. Thereby, the current flowing through each branch breaker 32 can be measured by the sensor 390.

Information regarding the use of power for each load circuit 38 measured by the measurement unit 33 is given to the processing unit 13 as input information. The information on the use of power measured by the measurement unit 33 may be an instantaneous value of a current value and a voltage value. However, the amount of power (considered as instantaneous power) every predetermined time (for example, 1 minute) and the instantaneous power are integrated. It is more desirable that it is at least one of the integrated electric energy.

It is desirable that the measurement unit 33 not only measures the power of each load circuit 38 but also measures the power of the main circuit. That is, it is preferable that the measurement unit 33 includes a sensor that measures electric power passing through the main breaker 31. Information on the use of power of the main circuit can be obtained as the instantaneous power or the total integrated power amount for each load circuit 38, but when the information obtained for each load circuit 38 is summed, the main circuit is measured. In many cases, errors are included in the information. Therefore, it is desirable to directly measure information on the power of the main circuit for the main circuit.

The processing unit 13 can acquire at least one of the instantaneous power and the integrated power amount for each load circuit 38 by using the input information obtained from the measurement unit 33 through the acquisition unit 18. Further, the processing unit 13 can acquire at least one of the instantaneous power and the integrated power amount for the main circuit.

(Cooperation with the first distributed power supply)
As shown in FIG. 1, the link adapter 10 according to the present embodiment is a first solar power generation device such as a photovoltaic power generator that reversely flows generated power to the power system (for example, reverse power flow to the power system is allowed). A third terminal portion 23 to which a first switch 51 connected between the distributed power source 41 and the main circuit on the power source side of the main breaker 31 can be connected. The third terminal portion 23 is electrically connected to the first terminal portion 21 and the second terminal portion 22. That is, the third terminal portion 23 is electrically connected to the main breaker 31 through the second terminal portion 22, and is electrically connected to the system power supply 25 through the first terminal portion 21.

The first switch 51 is controlled to be turned on when the first distributed power source 41 is connected to the power system, and to be turned off when the first distributed power source 41 is disconnected from the power system. . That is, the first switch 51 turns off the first distributed power supply 41 when the power supply from the system power supply 25 is stopped, or when an abnormality occurs in the system power supply 25 or the first distributed power supply 41. Provided to disconnect. Moreover, the 1st switch 51 contains the earth-leakage breaker.

The first switch 51 is, for example, a 3P3E type (3 poles, 3 elements) breaker as shown in FIG. The first switch 51 includes a terminal unit 510 to which the power cable of the first distributed power supply 41 is connected. In the present embodiment, the terminal portion 510 includes three terminal portions corresponding to the neutral line, the first voltage line, and the second voltage line.

If the first switch 51 can secure a space in the distribution board 30, the first switch 51 can be arranged in a different location from the linkage adapter 10 in the internal space of the distribution board 30. In this case, the dimensions of the container body 14 of the linkage adapter 10 are designed so that a first mounting space for arranging the first switch 51 is formed inside the distribution board 30. However, when the device body 14 of the link adapter 10 is formed to have the same size as the current limiter as in the present embodiment, the first switch 51 is disposed inside the existing distribution board 30. A space cannot be secured independently of the installation space of the link adapter 10.

Therefore, as shown in FIG. 2, the link adapter 10 of the present embodiment includes a first mounting space SP <b> 1 in which the first switch 51 is mounted in a part of the body 14. The first switch 51 can be attached to and detached from the first attachment space SP1. The first attachment space SP1 is a recess formed in the container body 14. The first mounting space SP1 is a plug in which a terminal (not shown) of the first switch 51 is electrically connected when the first switch 51 is mounted in the first mounting space SP1. It has an expression connection (not shown). In the present embodiment, this plug-in connection portion constitutes the third terminal portion 23. In the example shown in FIG. 2, the container body 14 includes one first mounting space SP1, but may include a plurality of first mounting spaces SP1.

That is, the link adapter 10 of the present embodiment has a first mounting space (concave) in which the first switch 51 for connecting the first distributed power source 41 that reversely flows the generated power to the power system is arranged. ) SP1 is provided in the container 14. Moreover, the 3rd terminal part 23 is provided in attachment space SP1, and when the 1st switch 51 is arrange | positioned in 1st attachment space SP1, it is connected to the 1st switch 51. .

Therefore, when the first switch 51 is connected to the third terminal portion 23 and the first distributed power supply 41 is connected to the first switch 51, the first distributed power supply 41 generates power. It becomes possible to supply electric power to the main breaker 31 side via the second terminal part 22, and the electric power generated by the first distributed power supply 41 is supplied to the system power supply 25 via the first terminal part 21. It is possible to reverse flow to the side.

For example, one of the terminal of the first switch 51 and the connection portion (third terminal portion 23) employs a structure in which two leaf springs face each other, and the other is between the two leaf springs. A structure including a plate-like conductor piece to be inserted into is adopted. This type of structure is similar to the structure employed in the relationship between the plug blade of the power plug and the blade receiving spring of the receptacle. With this configuration, when the first switch 51 is mounted in the first mounting space SP1, the first switch 51 and the third terminal portion 23 are electrically connected. The terminal of the first switch 51 has the same structure (male connector) as the plug blade of the power plug, and the third terminal portion 23 of the linkage adapter 10 has the same structure (female connector) as the receptacle. It is preferable.

In the configuration described above (the configuration in which the coordination adapter 10 includes the first mounting space SP1), if the distribution board 30 to which the coordination adapter 10 is installed is installed in a consumer, the first like a solar power generation device. When the distributed power source 41 is installed in the consumer, the first switch 51 can be retrofitted to the first mounting space SP1. In other words, when the customer needs the first distributed power supply 41, the first switch 51 is installed inside the distribution board 30 to connect the first distributed power supply 41 to the system. It becomes possible to make it.

The link adapter 10 of the present embodiment further includes a built-in sensor 24 that measures the power that has passed through the first switch 51 as shown in FIG. The built-in sensor 24 is provided between the second terminal portion 22 and the third terminal portion 23. That is, in the present embodiment, the power generated by the first distributed power supply 41 is measured by the built-in sensor 24 provided in the linkage adapter 10. The built-in sensor 24 includes, for example, a current sensor that measures a current value passing through each line in order to measure the power received through the third terminal unit 23, and the current value measured by the current sensor and the voltage value between the lines. And to measure the power.

Information on the power measured by the built-in sensor 24 is given to the processing unit 13 as input information through the acquisition unit 18. Here, the information related to the power measured by the built-in sensor 24 may be an instantaneous value of a current value and a voltage value, but the amount of power for each predetermined time (for example, 1 minute) (considered as instantaneous power) and the instantaneous power. It is desirable that it is at least one of the integrated electric energy.

The processing unit 13 uses the input information obtained from the built-in sensor 24 through the acquisition unit 18 to acquire at least one of the instantaneous power and the integrated power amount for the power generated by the first distributed power supply 41. Is possible. Moreover, since the processing unit 13 acquires the power used for each load circuit 38 based on the input information from the measurement unit 33, the surplus power (or, alternatively, the difference from the power generated by the first distributed power source 41 is used. It is possible to calculate the power that has undergone reverse power flow. That is, the processing unit 13 uses the information obtained from the built-in sensor 24 and the information from the measurement unit 33 to calculate the power reversely flowed to the power system out of the power generated by the first distributed power supply 41. can do.

Although not shown, when the first distributed power source 41 is used in combination with a power storage device, a switch may be provided between the first terminal portion 21 and the second terminal portion 22. In this configuration, when the power required by the load circuit 38 can be satisfied by the power of the first distributed power supply 41 and the power of the power storage device, the power system is disconnected from the load circuit 38 by the switch, and the load circuit 38 When power to be used is insufficient, an operation of connecting a power system is possible. The operation of the switch is controlled by the processing unit 13.

The process in which the processing unit 13 generates output information using information related to the power generated by the first distributed power supply 41 as input information is required only when the first distributed power supply 41 is connected. Therefore, when the first distributed power supply 41 is connected, it is desirable that the processing unit 13 reads the corresponding program and data (program and data for processing information related to power measured by the built-in sensor 24). For example, when the processing unit 13 receives a predetermined radio signal from the first distributed power supply 41 via the second communication I / F unit, the processing unit 13 transmits the corresponding program and data to the first communication I / F unit 11. Alternatively, it is received through the second communication I / F unit 12. The program and data may be registered in the processing unit 13 in advance, and the required program and data may be activated when the first distributed power supply 41 is connected. However, even when the program and data are registered in the processing unit 13 in advance, when the first distributed power supply 41 is connected, the latest program and data (program and data update information) are read again. It is preferable that the program and data are not configured to be selected from options but configured to be read when necessary.

If it is clear that the first distributed power supply 41 is not used, the third terminal unit 23 is not necessary. Therefore, the cooperation adapter 10 that does not include the third terminal portion 23 may be attached to the distribution board 30.

(Cooperation with presentation device)
Below, operation | movement of the cooperation adapter 10 is demonstrated. Here, it is assumed that the first distributed power supply 41 is not connected to the linkage adapter 10. Even if the watt-hour meter 20 having the communication function is not installed in the consumer, the link adapter 10 performs the following operation if the measurement unit 33 is provided.

The processing unit 13 acquires information on the power for each load circuit 38 measured by the measurement unit 33 through the acquisition unit 18, generates output information using this information as input information, and outputs the output information to the second communication I / F unit. 12 to output. The processing unit 13 generates output information in an easy-to-understand format when presented to the user by performing processing such as input information aggregation and graphing. In this case, the output information is sent to the presentation device 71 having a display (screen) through the second communication I / F unit 12.

When the coordination adapter 10 generates a plurality of types of output information and not all output information can be displayed on one screen of the presentation device 71, the content displayed on the screen is switched. Therefore, it is desirable that the presentation device 71 is an operation display device provided with an operation unit operated by the user in addition to the display. The operation unit of this type of operation display device uses a switch provided separately from the display, or a touch switch superimposed on the screen of the display.

The presentation device 71 is a device that presents information to the user. In addition to a dedicated device that communicates with the second communication I / F unit 12, a smartphone or tablet terminal that communicates through the second communication I / F unit 12 A device selected from the above is used. In addition, in order to use terminal devices, such as a smart phone and a tablet terminal, what is necessary is just to make a terminal device run the application program which functions a terminal device as the presentation apparatus 71. FIG.

As in the above-described operation example, when the watt-hour meter 20 having the communication function is not installed at the consumer, the processing unit 13 cannot acquire input information from the watt-hour meter 20. On the other hand, when the electricity meter 20 having a communication function is installed in the consumer, the processing unit 13 also acquires input information from the electricity meter 20. Therefore, in order to generate the output information presented to the presentation device 71, the processing unit 13 can use the input information obtained from the watt-hour meter 20 alone. The input information obtained from the watt-hour meter 20 includes the amount of power used by the consumer measured by the watt-hour meter 20, information on demand response notified from the management device 62, and the like. The processing unit 13 processes the input information acquired from the watt-hour meter 20 into a format that can be presented to the presentation device 71 and outputs the processed information to the presentation device 71.

(Cooperation with equipment)
The second communication I / F unit 12 can communicate not only with the presentation device 71 but also with the equipment device 72, the controller 70, and the communication device (wireless router) 73 as described above. Here, the second communication I / F unit 12 incorporated in advance in the linkage adapter 10 may be configured to be able to communicate only with any of the presentation device 71, the facility device 72, the controller 70, and the communication device 73. .

For example, when the cooperation adapter 10 has a function of sending output information to the presentation device 71 as in the above-described operation example, the presentation device 71 is required to communicate with the cooperation adapter 10. Communication with the incorporated second communication I / F unit 12 is possible. On the other hand, in this case, communication with the facility device 72, the controller 70, and the communication device 73 is not essential for the minimum function of the link adapter 10. In this case, the cooperation adapter 10 may be configured to add a second communication I / F unit 12A for communicating with the facility device 72, the controller 70, and the communication device 73 as a retrofit.

When the communication adapter 10 shown in FIG. 2 needs to communicate with the equipment 72, the controller 70, and the communication device 73, the second communication I / F unit 12A is added to communicate with these devices. The structure to be adopted is adopted. The second communication I / F unit 12 </ b> A added to the cooperation adapter 10 is attached to the body 14 of the cooperation adapter 10.

In the usage example illustrated in FIG. 3, the link adapter 10 performs wireless communication with the communication device 73 and WiFi (registered trademark) by updating the firmware of the processing unit 13 and adding the second communication I / F unit 12A. In addition, a configuration is employed in which wireless communication is performed with the controller 70 using specific low-power wireless communication. In this configuration, the communication device 73 communicates with a terminal device that functions as the management device 61, the controller 70, the facility device 72, and the presentation device 71.

In the case where the second communication I / F unit 12 incorporated in the link adapter 10 communicates only with the presentation device 71, the second communication I / F unit 12 is, for example, wirelessly based on WiFi (registered trademark). It only needs to be able to communicate. When communication with the controller 70 is required for the link adapter 10, a second communication I / F unit 12 </ b> A having a specific low power wireless communication function is attached to the link adapter 10. Further, when communication with the communication device 73 is required, the second communication I / F unit 12 incorporated in the link adapter 10 enables the processing unit 13 to communicate with the communication device 73. The firmware is updated.

When communicating with the facility equipment 72, the link adapter 10 is provided with a function of managing the equipment 72. That is, the processing unit 13 generates output information that manages the operation state of the equipment device 72 using the input information. The input information used when managing the operating state of the equipment 72 includes information on the amount of power used by the consumer acquired from the wattmeter 20 or the demand response, and information on the power for each load circuit 38 acquired from the measurement unit 33. including. Further, the processing unit 13 may include the information regarding the operation state of the equipment device 72 acquired from the equipment device 72 as the input information used for generating output information for managing the operation state of the equipment device 72.

For example, when the cooperation adapter 10 communicates with the controller 70 and the processing unit 13 manages the operation of the equipment device 72, the processing unit 13 acquires information about the equipment device 72 through the controller 70, and the processing unit 13 receives input information. The information for managing the equipment 72 may be generated based on the information and the generated information may be delivered to the controller 70. In this case, the processing unit 13 adds the information related to the facility device 72 acquired from the controller 70 to the input information, and outputs the output information (including the facility device 72) based on the input information (including information related to the facility device 72 acquired from the controller 70). Information to be managed).

Information (input information) used for generating output information is given to the processing unit 13 through the first communication I / F unit 11 and the second communication I / F unit 12. The processing unit 13 executes the program for managing the equipment device 72 to generate output information using the input information as described above, and controls the equipment device 72. For example, in order to save power according to the demand response, the link adapter 10 controls the equipment device 72 having a low priority to stop or controls the equipment device 72 to shift to an operation state in which power consumption is reduced. To the equipment 72.

By the way, the operation | movement mentioned above is operation | movement similar to the controller 70, and when the controller 70 manages the equipment 72, the information acquired from the watt-hour meter 20, the information acquired from the measurement unit 33, the information acquired from the equipment 72 Need. Since the controller 70 communicates with the equipment device 72, the controller 70 directly acquires information about the equipment device 72 from the equipment device 72. In addition, the controller 70 acquires information from the watt-hour meter 20 and the measurement unit 33 from the cooperation adapter 10.

Here, if the coordination adapter 10 and the controller 70 try to manage the equipment 72 at the same time, there is a possibility that they interfere with each other. For this reason, when the second communication I / F unit 12 communicates with the controller 70, the processing unit 13 is prohibited from processing the facility device 72. Note that the second communication I / F unit 12 uses, for example, a radio transmission path by specific low power radio when communicating with the controller 70.

Usually, it is difficult to desire a high processing capacity for the processor used in the processing unit 13 due to cost restrictions, and the processing contents when managing the equipment 72 are limited. In contrast, in general, the processor used in the controller 70 has a higher processing capability than the processing unit 13, and the interface unit provided in the controller 70 has a higher function than the cooperative adapter 10.

Therefore, when the facility device 72 is simply managed, the link adapter 10 is used, and when advanced processing is required by the management of the facility device 72, the controller 70 is used. This type of processing performed by the controller 70 includes processing for managing the operating state of the equipment device 72 in accordance with the time schedule, handling of abnormality of the equipment device 72, and the like.

(Cooperation with communication devices)
When the second communication I / F unit 12 communicates with a communication device 73 such as a router, the link adapter 10 can communicate with the management device 61 or the management device 62 through the communication device 73. The link adapter 10 can use this communication path when receiving firmware updater.

In addition, the presentation apparatus 71 mentioned above may communicate with the cooperation adapter 10 via the communication apparatus 73, without communicating directly with the cooperation adapter 10 as shown in FIG. That is, when a wireless LAN (Local Area Network) using the communication device 73 as an access point is constructed in the consumer, the presentation device 71 adopts a configuration that communicates with the coordination adapter 10 via the communication device 73. Also good. Furthermore, when the equipment device 72 capable of communicating with the communication device 73 is installed in the consumer, or when the controller 70 capable of communicating with the communication device 73 is provided in the consumer, the presentation device 71 is The facility device 72 or the controller 70 may be managed through the communication device 73.

When the main breaker 31 and the branch breaker 32 are attached to the distribution board 30, the linkage adapter 10 and the measurement unit 33 described above are attached to the distribution board 30 together. For example, the distribution board 30 including not only the main breaker 31 and the branch breaker 32 but also the linkage adapter 10 and the measurement unit 33 is shipped from the factory. Of course, the cooperation adapter 10 and the measurement unit 33 may be attached to the distribution board 30 at the construction site of the customer.

(Cooperation with the second distributed power supply)
The distribution board 30 of the present embodiment not only generates the generated power but also the first distributed power source 41 that reversely flows the generated power to the power system (for example, the reverse power flow to the power system is allowed). It is also possible to connect a second distributed power source 42 that does not cause reverse power flow to the power system (for example, reverse power flow to the power system is prohibited). In the cabinet 35 of the distribution board 30, a second switch 52 is arranged in a part of the space for installing the branch breaker 32 in order to connect the second distributed power source 42 as shown in FIG. 2. A second mounting space SP2 is provided. Specifically, the second mounting space SP2 is provided on the first side in the direction D1 of the conductive bar set 37 and on one side in the direction D2 (lower right side in FIG. 2).

In the present embodiment, the mounting base 34 to which the second switch 52 is attached is mounted in the second mounting space SP2. In the example shown in FIG. 2, the mounting base 34 (second switch 52) is arranged in the mounting space SP2 corresponding to the three branch breakers 32, but the second mounting space SP2 is the second opening / closing. Depending on the size and the number of the containers 52, it is sufficient that dimensions corresponding to 1 to an integer number of the branch breakers 52 are vacant.

The mounting base 34 is attached to the distribution board 30 before factory shipment or on-site construction at the customer, similarly to the linkage adapter 10. The distribution board 30 can leave a second mounting space SP <b> 2 corresponding to the mounting table 34 without mounting the mounting table 34. However, if the mounting base 34 is left unattached to the distribution board 30, there is a possibility that the branch breaker 32 is erroneously attached to the second mounting space SP <b> 2, and the conductive portion (exposed conductive bar). There is a possibility that contact resistance may increase due to dust adhering to (part) or an oxide film. Due to the above circumstances, it is desirable that the mounting base 34 is attached to the distribution board 30 in advance. If it is clear that the second distributed power source 42 will not be used for the time being in the second mounting space SP2, a spare branch breaker 32 may be mounted.

The second distributed power source 42 is selected from a fuel cell, a power storage device, an electric vehicle equipped with a storage battery, and the like. It is assumed that the electric vehicle includes a converter that performs bidirectional power conversion between alternating current and direct current, and does not require a separate charger. In addition, the second distributed power source 42 may be a distributed power source that converts renewable energy into electric power as in the case of a photovoltaic power generation device, as long as a reverse power flow to the power system is not performed. When the second distributed power source 42 is connected to the distribution board 30, the second distributed power source 41 and the main circuit are connected in the same manner as the first switch 51 is necessary between the first distributed power source 41 and the main circuit. A second switch 52 is required between the mold power source 42 and the main circuit.

The second switch 52 can be attached to and detached from the mounting base 34. The relationship between the second switch 52 and the mounting base 34 is the same as the relationship between the first switch 51 and the link adapter 10, and the second switch 52 is attached to and detached from the mounting base 34. It is installed so that it becomes possible.

The second switch 52 includes a leakage breaker and has a function of disconnecting the second distributed power source 42 from the main circuit when an abnormality occurs in the second distributed power source 42.

The second switch 52 may be directly connected to the conductive bar set 37 without using the mounting base 34. An example of the second switch 52 in this case is shown in FIG. The second switch 52 is, for example, a 3P3E type (3 poles, 3 elements) breaker. The second switch 52 includes a terminal portion 520 to which a power cable of the second distributed power source 42 is connected. The second switch 52 includes an insertion port 521 to which the conductive bar set 37 is connected. A terminal (not shown) is provided in the insertion port 521. In the present embodiment, the terminal portion 520 includes three terminal portions corresponding to the neutral line, the first voltage line, and the second voltage line. Moreover, the insertion port 521 includes three insertion ports, and three terminals are provided corresponding to the three insertion ports, respectively.

When the second distributed power source 42 is connected to the conductive bar set 37 via the second switch 52, a plurality of electric power generated by the second distributed power source 42 is transmitted via the conductive bar set 37. The load circuit 38 can be supplied.

When the second distributed power source 42 is connected to the distribution board 30, a program and data corresponding to the second distributed power source 42 are set in the processing unit 13 of the linkage adapter 10. That is, since the second distributed power source 42 does not always perform reverse power flow to the power system (for example, reverse power flow to the power system is prohibited), the processing unit 13 of the link adapter 10 is connected to the power system. Control is performed to prevent reverse power flow.

That is, the processing unit 13 compares the power supplied from the second distributed power source 42 to the main circuit and the power supplied to the load circuit 38, and the power supplied from the second distributed power source 42 is The output of the second distributed power source 42 is adjusted so as to be smaller than the power supplied to the load circuit 38. For example, the processing unit 13 adjusts the output of the second distributed power source 42 by wireless communication through the second communication I / F unit 12.

Note that the processing unit 13 does not directly adjust the output of the second distributed power source 42, but the power supplied from the second distributed power source 42 to the main circuit with respect to the second distributed power source 42. The power supplied to the load circuit 38 may be transmitted. In this case, the second distributed power source 42 compares the power supplied to the load circuit 38 with the power supplied from the second distributed power source 42 to the main circuit, and adjusts its output.

The second distributed power source 42 is configured to supply only electric power, such as a fuel cell or a solar power generation device, and stores not only electric power (discharge) but also electric power storage (electric storage) like an electric storage device or an electric vehicle. ) Can be selected. The second distributed power source 42 that only supplies power is only prevented from the reverse power flow by the above-described operation, but the second distributed power source 42 that performs charging and discharging prevents the reverse power flow. As well as managing the amount of electricity stored. Therefore, the program and data set in the cooperation adapter 10 are changed according to the type of the second distributed power source 42.

For example, the storage battery of the power storage device or the electric vehicle is charged using the power of the system power supply 25 or charged using the power of the first distributed power supply 41. When charging is performed using the power of the system power supply 25, the timing of charging is managed so that nighttime power whose unit price is relatively low is used. In addition, the storage amount of the storage battery of the power storage device or the electric vehicle is managed according to various conditions such as the amount of power used on the next day or the life of the battery. When the power storage device or the storage battery of the electric vehicle is used for the purpose of reducing the power purchased from the system power supply 25 or for the purpose of adjusting the power of the reverse power flow, the link adapter 10 can respond to the purpose. Control.

(Cooperation with independent distribution board)
Hereinafter, the distribution board system of this embodiment will be described. As shown in FIG. 1, the distribution board system of the present embodiment is connected to a second distributed power source 42 that can output power while power supply from the system power supply 25 is stopped. An electric panel 30 and a self-supporting distribution board 80 are provided.

Of the second distributed power source 42 described above, a photovoltaic power generation device, a power storage device, an electric vehicle equipped with a storage battery, and the like provide AC power to the equipment 72 even when the power supply from the system power source 25 is stopped. It is possible to output. Such a second distributed power source 42 includes a terminal that outputs AC power in a state where power supply from the system power source 25 is stopped, separately from a terminal that is connected to the main circuit of the distribution board 30. Yes. Hereinafter, the power output from this terminal is referred to as a self-supporting output.

Since the capacity that can be supplied is limited, the self-sustained output is supplied only to specific equipment 72 in the consumer. The specific equipment 72 that receives the self-sustained output is connected to a second branch breaker 82 provided in the self-sustained distribution board 80.
