Description

[Technical field]

[0001] The present invention relates to a power supply system that supplies power to a complex facility including a plurality of power supply destinations, and a method for restoring power in the event of a power outage. [Background technology]

[0002] In recent years, power supply systems that distribute power from a commercial power source to individual areas such as a plurality of dwelling units (H) included in a given zone such as an apartment building (B) during power restoration after a power outage caused by a large-scale disaster such as an earthquake have become widespread. Among these, a power supply system that supplies power to a plurality of dwelling units includes a distribution board (2) that distributes power to the plurality of dwelling units, a zone power meter (M1) that measures the amount of power used in the apartment building, a common power source that is shared in the apartment building and includes a storage battery (SC) that stores at least power from the commercial power source, and a control device (10) that controls the storage of power in the storage battery and the discharge of power from the storage battery according to the amount of power used measured by the zone power meter, in which the distribution board selects the power to be supplied to the plurality of dwelling units from either the commercial power source or the common power source according to an instruction from the control device, and the control device instructs the distribution board to supply power from the common power source to at least one of the plurality of dwelling units when the amount of power used measured by the zone power meter reaches a specified value (see, for example, Patent Document 1).

[0003] However, the above power supply system does not take into account the location information of the occupants of the apartments (hereinafter also referred to as private areas), and supplies power to each private area uniformly from the storage battery when a power outage occurs, regardless of whether the occupants are at home or away from the private areas, and when power is restored, resumes power supply to each private area uniformly from the grid. After a large-scale disaster such as an earthquake occurs, it is quite likely that items will be scattered in the private areas. For example, if a flammable object such as a curtain is close to an appliance such as an electric heater and the occupant is not in the private area, there is a high possibility that an electrical fire will break out in the private area when power is restored and the occupant will not notice it. For example, when a power outage occurs while using an electric heater with an analog switch structure, the switch will remain in the ON position. In this state, when power is restored, the electric heater will start operating regardless of the occupant's intention. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2011-130649 A [Patent Document 2] JP 2017-070034 A Summary of the Invention [Problem to be solved by the invention]

[0005] The present invention has been made in consideration of the above-mentioned problems, and has as its ultimate objective the provision of a power supply system that is capable of preventing the occurrence of electrical fires when power is restored during a power outage, even when the residents are not present in the private areas of an apartment building. [Means for solving the problem]

[0006] To solve the above problems, the present invention provides: Supplying electricity to a complex facility including multiple power supply destinations, A distributed power source capable of supplying power to the plurality of power supply destinations; a power detection means for detecting power supplied from a power grid and / or power supplied to each of the plurality of power supply destinations, and for controlling power supply to the plurality of power supply destinations; In the event of a power outage, the power detection means is instructed to stop power supply to the plurality of power supply destinations. and a management device that instructs the power detection means to start supplying power to the plurality of power supply destinations when power is restored, the management device acquires location information of a resident of a predetermined power supply destination among the plurality of power supply destinations, and determines whether the resident is present at the predetermined power supply destination by comparing the location information with an address of the predetermined power supply destination that is registered in advance in the management device; The power supply system is characterized in that when the management device determines that the occupant is not present at the designated power supply destination when power is restored after a power outage, it prohibits the power detection means from starting to supply power to the designated power supply destination.

[0007] According to the present invention, when power is restored from a power outage following a large-scale disaster such as an earthquake, it is possible to prevent power supplied from the grid to a complex facility from being uniformly supplied to multiple power supply destinations. For example, if power is supplied to a power supply destination where no occupants are present and an electrical appliance such as an electric heater is operated, there is a risk that combustible materials around the electrical appliance may ignite, causing an electrical fire, and the occupants may not notice the electrical fire. When power is restored, the management device determines that the occupants are absent from the specified power supply destination based on the location information, thereby making it possible to prevent an electrical fire from occurring.

[0008] In addition, the present invention may be an electric power supply system characterized in that the management device acquires location information of the resident based on a GPS function of an electronic terminal device owned by the resident, making it possible to acquire location information of the resident more easily and accurately.

[0009] In addition, in the present invention, the power supply system may be characterized in that the management device instructs the power detection means to temporarily supply the power supplied from the distributed power source to the power detection means to the specified power supply destination during a power outage, and instructs the power detection means to stop supplying the power supplied from the distributed power source to the power detection means to the specified power supply destination when power is restored. In this way, even during a power outage, the power supplied from the distributed power source can be used at the specified power supply destination. For example, even during a power outage, it is possible to turn on a television at the specified power supply destination and obtain earthquake information.

[0010] Furthermore, in the present invention, the power supply system may be characterized in that the management device acquires height information from the ground surface of the electronic terminal device owned by the resident, and further determines whether the resident is at the specified power supply destination based on the height information. This allows the management device to more accurately acquire location information of the resident and more accurately determine whether the resident is at the specified power supply destination. If the management device cannot acquire height information of the electronic terminal device from the ground surface, the management device can determine that the resident is staying in a complex, but cannot determine which floor of the complex the resident is staying on, and there is a possibility that the management device may erroneously determine that the resident is at the specified power supply destination even if the resident is staying at the entrance of the complex, for example.

[0011] To solve the above problems, the present invention provides: A power restoration method for resuming power supply from a power grid to a complex facility including a plurality of power supply destinations during a power outage, comprising: A step of stopping the supply of power from the distributed power source; acquiring location information of the residents of the plurality of power supply destinations based on a GPS function of an electronic terminal device owned by the residents; A step of collating the location information with an address of a predetermined power supply destination registered in advance in a management device to determine whether the resident is present at the predetermined power supply destination; When the management device determines that the occupant is not present at the specified power supply destination, and prohibiting the power detection means from starting power supply to the predetermined power supply destination.

[0012] According to the present invention, when power is restored after a power outage, the location information of the occupants in the complex is used to determine whether the occupants are at the designated power supply destination, and if the occupants are present, power supply is started, but if the occupants are absent, power supply is not started. Even if the occupants are present at the designated power supply destination, it is possible for the occupants to decide not to start power supply.

[0013] The above means for solving the problems can be used in combination with each other whenever possible. Effect of the Invention

[0014] According to the present invention, it is possible to prevent the occurrence of an electrical fire when power is restored after a power outage, thereby providing safety and security in the use of electricity. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0016] [Application example] The power supply system in this application example has a mechanism for starting or prohibiting the start of power supply to each power supply destination in a complex facility including multiple power supply destinations when power is restored during a power outage caused by an earthquake or the like (hereinafter simply referred to as "power outage"). The power supply system in this application example includes a management device, which compares location information of a resident of a power supply destination with the address of the resident registered in advance, and when it is determined that the resident is not present at the power supply destination of the resident, prohibits the start of power supply to the power supply destination of the resident.

[0017] FIG. 2 is a block diagram showing a schematic configuration of a power supply system 1 to which the present invention can be applied, and the functions of the power supply system 1 before power is restored during a power outage. The power supply system 1 according to this application example includes an apartment building 2 with a smart meter 4 for the apartment building, a smart meter 5 for the private area, and a storage battery 10 inside the apartment building 2, and includes a management system 11 and a smart management system 13, which is a control system for the apartment building's smart meter 4 and the smart meter 5 for the private area, outside the apartment building 2. It is also assumed that the power supply system 1 according to this application example is applied to the apartment building 2. In this case, the apartment building 2 is an example of a complex facility including multiple power supply destinations. Also, while FIG. 2 shows only a storage battery 10 as a power supply source other than the grid 3, it may also include power generation devices such as solar cells and wind power generators. The storage battery 10 may also be a storage battery related to so-called V2H (Vehicle to Home).

[0018] As shown in FIG. 2, before power is restored during a power outage, the power supply system 1 has a mechanism for supplying power from a storage battery 10 in an apartment house 2 through a smart meter 4 in the apartment house and a smart meter 5 in the private area to a private area 6, for example, a resident's room, via a distribution board 7 installed in the private area 6. In this case, the private area 6 is an example of a plurality of power supply destinations and a predetermined power supply destination. Here, in this application example, during a power outage, power is not supplied from the grid 3 to the private area 6, and power is temporarily supplied from the storage battery 10 to the private area 6. In addition, in this application example, power restoration means, for example, that after a power outage, the management system 11 instructs the smart meter 4 in the apartment house and the smart meter 5 in the private area to start supplying power from the grid 3 to the private area 6 and instructs the storage battery 10 to stop supplying power to the private area 6. Hereinafter, solid arrows indicate the flow of power, and dashed arrows indicate the flow of communication. Also, dashed arrows indicate a state in which power supply from the grid 3 is stopped.

[0019] 2, the power supply system 1 is electrically connected to a grid 3. When the power supplied by the storage battery 10 is less than the power consumption of the multiple power supply destinations, causing a power shortage, it is possible to purchase power from the grid 3, for example. When the power supplied by the storage battery 10 is more than the power consumption of the multiple power supply destinations, it is possible to sell the surplus power to the grid 3, for example. The grid 3 may be operated by a so-called retail electricity supplier, or may be operated by a general electricity supplier.

[0020] In addition, in this application example, the apartment smart meter 4 and the private smart meter 5 installed in the apartment 2 can communicate with the smart management system 13 via a wireless Internet line (not shown). The management system 11 and the smart management system 13 are connected by a wireless line or a wired line. More specifically, the management system 11 and the smart management system 13 may be server devices provided on the cloud by the management company that is the operator of the power supply system 1. However, the management system 11 and the smart management system 13 may be connected by wired communication and may not necessarily be provided on the cloud as long as they are capable of sending and receiving information between the apartment smart meter 4 and the private smart meter 5 in the power supply system 1.

[0021] Furthermore, the electricity consumed in the apartment building 2 can be measured by the apartment building's smart meter 4, and the electricity consumed in the private area 6 can be measured by the private area's smart meter 5. The apartment building's smart meter 4 and the private area's smart meter 5 are managed by a smart management system 13.

[0022] In addition, a storage battery power conditioner (not shown) including a bidirectional DC / DC converter that raises and lowers the charge / discharge voltage, and a DC / AC converter that converts the direct current / alternating current of the voltage related to the charge / discharge of the storage battery 10 is connected to the storage battery 10. Note that, instead of the storage battery 10, a distributed power source including a power generation device such as a solar cell in addition to the storage battery 10 may be provided.

[0023] The power supply system 1 in this application example has different functions when power is restored after a power outage depending on whether or not a resident is present in the private area 6. FIG. 4 is a block diagram showing a schematic configuration of the power supply system 1 to which the present invention can be applied, and the functions of the power supply system 1 when power is restored after a power outage and a resident is absent from the private area 6. The dashed arrows in FIG. 4 extending from the storage battery 10 to the smart meter 4 in the apartment building and the power outage dedicated outlet 14 indicate a state in which power supply from the storage battery 10 has been stopped. The arrow extending from the smart meter 5 in the private area to the distribution board 7 and the arrow extending from the distribution board 7 to the home appliances 8 indicate a state in which power supply from the storage battery 10 has been stopped. The arrow extending to the right indicates a state in which the power supply from the grid 3 is stopped. As shown in FIG. 4, when power is restored during a power outage, the management system 11 acquires the location information of the resident from the smartphone 16 owned by the resident using the GPS 15, compares the location information with the address of the resident registered in advance in the management system 11, and if it determines that the resident is not present in the private area 6, prohibits the start of power supply from the smart meter 5 in the private area to the distribution board 7. Therefore, since it is impossible to use electricity in the private area 6 where the resident is not present, the risk of an electrical fire can be reduced even if a large-scale disaster such as an earthquake occurs before the power outage and items are scattered in the private area 6, and flammable items 8 such as curtains are close to home appliances 7 such as electric heaters. Example 1 A power supply system 1 according to a first embodiment of the present invention will be described in detail below with reference to the drawings. Note that the power supply system 1 according to the present invention is not intended to be limited to the following configuration.

[0024] <System configuration> FIG. 1 is a block diagram showing a schematic configuration of a conventional power supply system 1 and functions of the power supply system 1 when power is restored after a power outage. When power is restored after a power outage, the power supply system 1 (shown in a simplified form in FIG. 1) in an apartment building 2 starts supplying power from a grid 3. In the power supply system 1, power supplied from the grid 3 is distributed to each private area 6 via a smart meter 4 in the apartment building and a smart meter 5 in the private area. When power is supplied to a distribution board 7 in each private area 6, it becomes possible to extract power through an outlet or the like in the private area 6, thereby enabling the use of home appliances 7. Here, the smart meter 4 in the apartment building and the smart meter 5 in the private area are components of the power detection means in the present invention.

[0025] In this embodiment, as described above, a power outage following an earthquake is assumed, and it is entirely conceivable that after an earthquake, objects will be scattered in the private area 6, and combustible objects 8, such as curtains, will be in close proximity to home appliances 7, such as electric heaters. In such a state, if power is restored to the private area 6 when no resident is present, there is a risk of an electrical fire breaking out. This is because the resident cannot willingly stop the restoration of power to the private area 6 or correct the state in which combustible objects 8 are in close proximity to the home appliances 7.

[0026] Returning now to the explanation of Fig. 2, as described above, during a power outage, power is not supplied from the grid 3 to the apartment building 2. Instead, power is supplied from the storage battery 10 to the exclusive area 6 via the smart meter 4 of the apartment building and the smart meter 5 in the exclusive area, and then through the distribution board 7 installed in the exclusive area 6. Here, the storage battery 10 corresponds to the distributed power source in the present invention.

[0027] During a power outage, the management system 11 obtains both power outage information from the grid 3 and earthquake information from the website 12 to determine that a power outage has occurred due to an earthquake. Based on this information, the management system 11 instructs the smart meter 5 in the private area 6 to turn off the breaker so that power is not supplied to the private area 6 via the smart management system 13. Similarly, the management system 11 then instructs the smart meter 4 in the apartment building to turn off the breaker via the smart management system 13. Note that the smart meter 4 in the apartment building and the smart meter 5 in the private area are able to receive communication from the management system 11 by receiving power from the storage battery 10. Here, the management system 11 corresponds to the management device in the present invention. The smart management system 13 is also a component of the power detection means in the present invention.

[0028] In addition, during a power outage, the storage battery 10 can also supply power to a power outage dedicated outlet 14 installed in the exclusive area 6. Therefore, it is not possible to take out electric power through the distribution board 7, and it is possible to temporarily take out electric power through the power failure dedicated outlet 14. The power failure dedicated outlet 14 is not used after the power is restored.

[0029] FIG. 3 is a flowchart showing the process before power is restored in the power supply system 1 shown in FIG. 2 during a power outage. The flow of the process will be described below with reference to FIG. 3. In this flowchart, first, when an earthquake occurs, power supply from the grid 3 is stopped (S101). At that time, power supply to the smart meter 4 is also stopped, so it is impossible to switch the breaker ON / OFF. Therefore, after the power supply from the grid 3 is stopped, the breaker in the smart meter 4 of the apartment house is maintained in the ON state (S102), and further, the breaker in the smart meter 5 of the private area is also maintained in the ON state (S103). Then, when a certain elapsed time (t1) has passed after the power supply from the grid 3 is stopped, the storage battery 10 automatically starts supplying power. As a result, power is temporarily supplied from the storage battery 10 to the private area 6 via the smart meter 4 of the apartment house and the smart meter 5 of the private area. At the same time, power is also supplied to the power outage dedicated outlet 14 installed in the private area 6 (S104). In this way, even during a power outage, it becomes possible to use power in the private area 6 by using the power outage dedicated outlet 14. After power supply from the storage battery 10 starts and the functions of the smart meter 4 in the apartment building and the smart meter 5 in the private area are restored, the management system 11 instructs the smart meter 5 in the private area to turn off the breaker, and similarly instructs the smart meter 4 in the apartment building to turn off the breaker. In this embodiment, since power is supplied from the storage battery 10 to both the smart meter 4 in the apartment building and the smart meter 5 in the private area during a power outage, it is possible to switch the breakers of both the smart meter 4 in the apartment building and the smart meter 5 in the private area on and off even during a power outage. Then, the process proceeds to power recovery. The subsequent flowcharts will be described later (see FIG. 6).

[0030] Here, we return to the explanation of FIG. 4. As described above, when power is restored in the event of a power outage, the power supply system 1 has different functions depending on whether the occupant is present in the private area 6 or not. In addition, when power is restored, the power supply from the storage battery 10 to the private area 6 is stopped, and power is supplied from the system 3 to the smart meter 5 of the private area via the smart meter 4 of the apartment building. Since the power supply from the storage battery 10 is stopped, it is impossible to take out power through the outlet 14 dedicated for power outages. The management system 11 may determine that the earthquake has stopped and power restoration is possible by obtaining both the power restoration information from the system 3 and the earthquake information from the website 12. Based on this information, the management system 11 may instruct the smart meter 4 of the apartment building to turn on the breaker via the smart management system 13. The function of the power supply system 1 when the occupant is present in the private area 6 is shown in detail in FIG. 5.

[0031] As shown in FIG. 4, after power is supplied from the grid 3 to the smart meter 5 in the exclusive area, the management system 11 acquires the location information of the resident from the smartphone 16 owned by the resident by the GPS 15. Then, the management system 11 checks the location information against the address of the resident registered in advance in the management system 11 and determines that the resident is absent from the exclusive area 6. In this case, the management system 11 does not instruct the smart meter 5 in the exclusive area to turn on the breaker so that power is not supplied to the exclusive area 6. That is, the breaker in the smart meter 5 in the exclusive area remains in the OFF state. Here, the address of the resident may be information that allows the location of the exclusive area 6 (so-called room number) to be grasped in detail. The smartphone 16 corresponds to the electronic terminal device in the present invention. The electronic terminal device in the present invention may be a terminal other than the smartphone 16, for example, a tablet PC.

[0032] FIG. 5 is a schematic configuration of the power supply system 1 according to the first embodiment, and a diagram showing a state in which a resident is in the private area 6. 5 is a block diagram showing the function of the power supply system 1 when power is restored during a power outage in the case where the power supply system 1 is in a power-restored state. The dashed arrows in FIG. 5 are the same as those in FIG. 4. In common with FIG. 4, the power supply system 1 has a mechanism in which, when power is restored, the power supply from the storage battery 10 to the private area 6 is stopped, and power is supplied from the grid 3 to the smart meter 5 of the private area via the smart meter 4 of the apartment building. Therefore, when power is restored, the power supply from the storage battery 10 is stopped, and it is impossible to take out power through the outlet 14 dedicated for power outages. In addition, the management system 11 may determine that the earthquake has stopped and power can be restored to the apartment building 2 by obtaining both power restoration information from the grid 3 and earthquake information from the website 12. Based on this information, the management system 11 may instruct the smart meter 4 of the apartment building to turn on the breaker via the smart meter management system 13.

[0033] As shown in FIG. 5, the management system 11 determines that the resident is present in the private area 6 by the same means as those shown in FIG. 4. In this case, the management system 11 instructs the smart meter 5 in the private area to turn on the breaker via the smart management system 13. Here, assuming that the resident is staying at the entrance of the apartment building 2 and the private area 6 is located on a floor above the entrance, the management system 11 may be able to acquire information on the height of the smartphone 16 owned by the resident from the ground. In this way, the management system 11 can determine on which floor of the apartment building 2 the resident is staying and can more accurately determine information on whether the resident is present in the private area 6.

[0034] As shown in Fig. 5, when a tenant is in the private area 6, power is supplied from the smart meter 5 in the private area to the distribution board 7, making it possible to use power in the private area 6. Since the tenant is in the private area 6, even if flammable materials 8 are in close proximity to the home appliance 7, it is possible to keep the flammable materials 8 away from the home appliance 7. Furthermore, even if the tenant does not realize that the flammable materials 8 are in close proximity to the home appliance 7 and smoke or fire occurs due to the operation of the home appliance 7, it is possible to take measures such as extinguishing the fire.

[0035] However, even if the resident is in the private area 6, there is a possibility that the resident cannot easily approach the home appliance 7 because objects are scattered after the earthquake. Alternatively, if the management system 11 does not have sufficient functionality to acquire height information from the ground of the smartphone 16 owned by the resident, the resident may be mistakenly recognized as being in the private area 6 even if the resident is staying on a different floor from the private area 6. In this embodiment, when the management system 11 determines that the resident is in the private area 6, the management system 11 may send a message to the smartphone 16 to confirm whether or not it is acceptable to supply power to the distribution board 7. By doing so, even if the resident is in the private area 6, the management system 11 may instruct the management system 11 to turn off the breaker of the smart meter 5 in the private area at the resident's will, thereby stopping the power supply to the distribution board 7. Alternatively, when the resident is in the private area 6, the breaker in the distribution board 7 may be turned off manually without using the smartphone 16.

[0036] FIG. 6 is a flowchart showing the process of power restoration in the power supply system 1 shown in FIG. 4 and FIG. 5 during a power outage. The flow of the process will be described below with reference to FIG. 6. In this flowchart, first, when power supply from the system 3 starts during power restoration, the management system 11 instructs the smart meter 4 of the apartment building to turn on the breaker (S105). Next, when a certain time (t2) has elapsed since power supply from the system 3 started, power supply from the storage battery 10 is automatically stopped (S106). Then, location information of the resident is acquired from the smartphone 16 owned by the resident by the GPS 15 (S107), and the location information is compared with the address of the resident registered in advance in the management system 11, and the management system 11 judges whether the resident is in the private area 6 or not (S108). The management system If the management system 11 determines that the resident is not in the exclusive area 6, the breaker of the smart meter 5 of the exclusive area is maintained in the OFF state (S109). When electricity is to be used in the exclusive area 6, the breaker of the smart meter 5 of the exclusive area may be switched ON by, for example, the resident returning to the exclusive area 6 and operating the smartphone 16. If the management system 11 determines that the resident is in the exclusive area 6, the management system 11 instructs the smart meter 5 of the exclusive area to switch the breaker ON (S110). Here, the management system 11 may send a message to the smartphone 16 owned by the resident to confirm whether or not it is OK to supply electricity to the exclusive area 6. In this way, the resident who receives the message can choose whether to start the power supply to the exclusive area 6 or to keep it stopped.
