  Below, the structure of the electric power supply system 100 which is 1st embodiment of the electric power supply system which concerns on this invention is demonstrated using FIG.

  The power supply system 100 is provided in a building (a house in the present embodiment), and the power storage device 12 is operated autonomously when the commercial power supply 90 is out of power. The power supply system 100 mainly includes a general distribution board 10, a power storage device 12, an interconnection breaker 13, a first relay 14, an important load 15, a branch breaker 16, a second relay 17, and an audio room 18. A third relay 19, a self-supporting output breaker 20, a fourth relay 21, a fifth relay 22, and a power path. The power path includes a first power path 31, a second power path 32, a third power path 33, a fourth power path 34, and a fifth power path 35.

  The general distribution board 10 distributes the electric power supplied from the commercial power supply 90 to the general load 10a.

  The general load 10a is a circuit connected to an electric appliance or the like that consumes electric power in a house, and the commercial power supply 90 is less likely to supply electric power during a power failure. For example, lighting of a room other than a living room is connected to the general load 10a. In the present embodiment, the house load (in-home load) includes an important load 15 (to be described later) and an audio room 18 in addition to the general load 10a.

  The first power path 31 is a path for distributing power. The first power path 31 is composed of a conducting wire or the like. One side of the first power path 31 is connected to the commercial power supply 90. The other side of the first power path 31 is connected to the general distribution board 10. A power sensor 45 that detects power supplied from the commercial power supply 90 is installed in the middle of the first power path 31.

  The power storage device 12 is a device that charges the power supplied from the commercial power supply 90 or discharges the power charged in the power storage device 12. The power storage device 12 is supplied with power from the commercial power supply 90 via the first power path 31, the general distribution board 10, and the second power path 32. The power storage device 12 mainly includes a storage battery 25 and a power conditioner 26.

  The storage battery 25 is configured to be able to charge and discharge electric power. The storage battery 25 is mainly composed of a lithium ion battery or the like.

In the middle of the second power path 32, the interconnection breaker 13 and the first relay 14 are installed.

  The interconnection breaker 13 is for cutting off the distribution of power in the second power path 32. When the distribution of power in the second power path 32 is interrupted by the interconnection breaker 13, the power from the commercial power supply 90 cannot be supplied to the power storage device 12.

When the first relay 14 is switched to ON, power can flow through the first relay 14. Further, when the first relay 14 is switched to OFF, power cannot flow through the first relay 14.

  The important load 15 is a circuit connected to an electric appliance or the like that consumes electric power in a house, and the necessity of supplying electric power during a power failure is higher than that of the general load 10a.

A branch breaker 16 and a second relay 17 are installed in the middle of the third power path 33.

  The branch breaker 16 is for cutting off the distribution of power through the third power path 33. When the distribution of power in the third power path 33 is interrupted by the branch breaker 16, the power from the commercial power supply 90 cannot be supplied to the important load 15 and the audio room 18.

  The second relay 17 switches whether power can be distributed. The second relay 17 is installed between the branch breaker 16 and the important load 15 in the third power path 33. When the second relay 17 is switched to ON, power can flow through the second relay 17. Further, when the second relay 17 is switched to OFF, electric power cannot flow through the second relay 17.

  The audio room 18 is a room (acoustic space) having acoustic devices such as amplifiers and speakers. In the audio room 18, a resident of the house can enjoy the sound by operating the acoustic device. Note that the audio room 18 (more specifically, a circuit provided in the audio room 18 and connected to the acoustic device) is included in the load in the house (home load).

  The fourth power path 34 is a path for distributing power. The fourth power path 34 is constituted by a conducting wire or the like. One side of the fourth power path 34 is connected to the middle part of the third power path 33 (hereinafter referred to as “first contact 41”). The first contact 41 is provided between the branch breaker 16 and the second relay 17 in the third power path 33. A third relay 19 is installed in the middle of the fourth power path 34. The other side of the fourth power path 34 is connected to the audio room 18.

  The third relay 19 switches whether power can be distributed. The third relay 19 is installed in the middle of the fourth power path 34. When the third relay 19 is switched to ON, power can flow through the third relay 19. Further, when the third relay 19 is switched to OFF, electric power cannot flow through the third relay 19.

  The fifth power path 35 is a path for distributing power. The fifth power path 35 is composed of a conducting wire or the like. One side of the fifth power path 35 is connected to the power storage device 12 (more specifically, the power conditioner 26).

  The other side of the fifth power path 35 is branched at the midway section 44, and one of the branches (hereinafter referred to as “fifth power branch path 35a”) is a midway section of the third power path 33 (hereinafter “second power path”). Contact 42 ”). The second contact 42 is provided between the second relay 17 and the important load 15 in the third power path 33.

  The other branched portion (hereinafter referred to as “fifth power branch path 35 b”) is connected to a midway portion (hereinafter referred to as “third contact 43”) of the fourth power path 34. The third contact 43 is provided between the third relay 19 and the audio room 18 in the fourth power path 34.

  A self-sustained output breaker 20 is installed in the middle of the fifth power path 35. The fourth relay 21 is installed in the middle of the fifth power branch path 35a. A fifth relay 22 is installed in the middle of the fifth power branch path 35b.

  The self-supporting output breaker 20 is for cutting off the power distribution of the fifth power path 35 (the fifth power branch path 35a and the fifth power branch path 35b). When the flow of power through the fifth power path 35 (the fifth power branch path 35a and the fifth power branch path 35b) is interrupted by the independent output breaker 20, the power from the power storage device 12 is transferred to the important load 15 and the audio room 18. The supply is impossible.

  The fourth relay 21 switches whether power can be distributed. The fourth relay 21 is installed in the middle of the fifth power branch path 35a. When the fourth relay 21 is switched to ON, power can flow through the fourth relay 21. In addition, when the fourth relay 21 is switched off, the power cannot flow through the fourth relay 21.

  The fifth relay 22 switches whether power can be distributed. The fifth relay 22 is installed in the middle of the fifth power branch path 35b. When the fifth relay 22 is switched to ON, power can flow through the fifth relay 22. Further, when the fifth relay 22 is switched to OFF, electric power cannot flow through the fifth relay 22.

  The control device 23 manages information in the power supply system 100 and controls each device constituting the power supply system 100. The control device 23 is connected to each device (each relay such as the first relay 14 and the power storage device 12) through a network constructed in the house (not shown). In addition, the control device 23 includes a display unit 27 on which information in the power supply system 100 is displayed.

  Further, the control device 23 can acquire information related to the operation of each device and control the operation. Specifically, the control device 23 can detect the occurrence of a power failure. Further, the control device 23 can detect the operation state of the power storage device 12 (specifically, whether the grid operation or the independent operation is performed). Moreover, the control apparatus 23 can detect the state of each breaker, such as the interconnection breaker 13. Further, the control device 23 can detect the state of each relay such as the first relay 14. The control device 23 can control the operation of each relay such as the first relay 14 (switch between ON and OFF).

  Control of the operation of each relay such as the first relay 14 is performed by dividing each relay into three preset blocks. Hereinafter, the three blocks are referred to as a first block B10, a second block B20, and a third block B30, respectively.

  The first relay B is included in the first block B10.

  The second block B20 includes a fourth relay 21 and a fifth relay 22. As for the operation of the fourth relay 21 and the fifth relay 22, exclusive control is performed such that when one is ON, the other is OFF.

  The third block B30 is divided into a third block B31 and a third block B32.

  The third block B31 includes the fourth relay 21 and the second relay 17. As for the operation of the fourth relay 21 and the second relay 17, exclusive control is performed such that when one is ON, the other is OFF.

  The third block B32 includes the fifth relay 22 and the third relay 19. In the operations of the fifth relay 22 and the third relay 19, exclusive control is performed such that when one is ON, the other is OFF.

  Thus, the fourth relay 21 is included in both the second block B20 and the third block B30 (more specifically, the third block B31). The fifth relay 22 is included in both the second block B20 and the third block B30 (more specifically, the third block B32).

  Thus, when the operation of the fourth relay 21 and the fifth relay 22 is controlled in the second block B20, the operation of each switch in the third block B30 is controlled according to the control. Specifically, when the operations of the fourth relay 21 and the fifth relay 22 are controlled in the second block B20, the operation of the second relay 17 is controlled in the third block B31 of the third block B30. In the third block B32, the operation of the third relay 19 is controlled.

  The power supply system 100 configured as described above has various modes that can be executed with respect to a power supply mode. The various modes are selected according to the lifestyle of the resident of the house. The power supply system 100 has a simulated power failure mode as one of the various modes.

  The simulated power failure mode is a mode in which the power storage device 12 is autonomously operated in a pseudo power failure state even when it is not during a power failure (that is, during a normal time). Here, in the present embodiment, the state at the time of a pseudo power failure refers to a state in which the power storage device 12 is disconnected from the commercial power source 90 and is not connected to the commercial power source 90 in a normal time. Thus, when the pseudo power failure mode is executed, the power storage device 12 can be operated independently even during normal times, and the power charged in the storage battery 25 in the power storage device 12 can be output from the power conditioner 26.

  Below, the supply mode of the electric power in the electric power supply system 100 is demonstrated using FIGS.

  First, with reference to FIG. 2, a power supply mode in the power supply system 100 when the audio room 18 is not normally used will be described.

  In this case, the power from the commercial power supply 90 is supplied to the general distribution board 10 via the first power path 31. In the general distribution board 10, the electric power from the commercial power supply 90 is distributed (supplied) to the general load 10a.

  In the third block B <b> 31, the second relay 17 is switched ON, and power can be distributed to the second relay 17. Thus, the power from the commercial power supply 90 is supplied to the important load 15 via the first power path 31, the general distribution board 10 and the third power path 33.

  Further, in the first block B10, the first relay 14 is switched ON, and power can be distributed to the first relay 14. Thus, power from the commercial power supply 90 is supplied to the power storage device 12 via the first power path 31, the general distribution board 10, and the second power path 32.

  As described above, when the audio room 18 is not normally used, the power from the commercial power supply 90 is supplied to the general load 10 a and the important load 15. In addition, the power storage device 12 can be charged with power from the commercial power supply 90.

  Next, a power supply mode in the power supply system 100 when the audio room 18 is used in a normal state will be described with reference to FIG.

  In this case, the power from the commercial power supply 90 is supplied to the general distribution board 10 via the first power path 31. In the general distribution board 10, the electric power from the commercial power supply 90 is distributed (supplied) to the general load 10a.

  In the third block B <b> 31, the second relay 17 is switched ON, and power can be distributed to the second relay 17. Thus, the power from the commercial power supply 90 is supplied to the important load 15 via the first power path 31, the general distribution board 10 and the third power path 33.

  Further, in the first block B10, the first relay 14 is switched OFF, and the power cannot flow through the first relay 14. That is, when the first relay 14 is switched to OFF, the power storage device 12 is disconnected from the commercial power supply 90 and enters a state in which power from the commercial power supply 90 cannot be supplied (a state during a pseudo power failure). The first relay 14 is switched from ON to OFF, for example, by a manual operation by a resident who uses the audio room 18.

  Thus, when the first relay 14 is switched from ON to OFF at normal times, the pseudo power failure mode is executed. That is, the power storage device 12 is operated independently, and the power charged in the storage battery 25 in the power storage device 12 can be output from the power conditioner 26.

  Further, when the second relay 17 is switched ON in the third block B31, the fourth relay 21 included in the third block B31 is switched OFF, and power cannot flow to the fourth relay 21. . Moreover, since the 4th relay 21 is also contained in 2nd block B20, the 5th relay 22 contained in the said 2nd block B20 will be switched ON, and it will be in the state which can distribute | circulate electric power to the 5th relay 22. FIG.

  In this way, the electric power output from the power storage device 12 by the independent operation is supplied to the audio room 18 through the fifth power path 35 (fifth power branch path 35b) and the fourth power path 34. Thus, a resident using the audio room 18 can enjoy the sound by operating the acoustic device using the power output from the power storage device 12 by the independent operation.

  As described above, since power is not allowed to flow through the fourth relay 21, the power output from the power storage device 12 by the independent operation is not supplied to the important load 15.

  Further, when the fifth relay 22 is switched to ON in the second block B20, the fifth relay 22 is also included in the third block B32, so that the third relay 19 included in the third block B32 is turned OFF. As a result, the power is not allowed to flow to the third relay 19. For this reason, the electric power from the commercial power supply 90 supplied to the general distribution board 10 is not supplied to the audio room 18.

  As described above, when the audio room 18 is used at normal time, the power from the commercial power supply 90 is supplied to the general load 10 a and the important load 15. Moreover, the pseudo power failure mode is executed, and the electric power output from the power storage device 12 by the self-sustained operation is supplied to the audio room 18. Note that power from the commercial power supply 90 is not supplied to the audio room 18.

  Here, the electric power from the commercial power supply 90 supplied to the general load 10a and the important load 15 depends on the use of an electric appliance (for example, a vacuum cleaner or a dryer) connected to the general load 10a and the important load 15. Thus, the voltage waveform may be distorted or the voltage may fluctuate (hereinafter simply referred to as “voltage fluctuation”). Therefore, for example, when the acoustic device is connected to the general load 10a and the important load 15, the supplied power fluctuates, so that the operation of the acoustic device becomes unstable and it is difficult to obtain good sound. Become.

  On the other hand, in this embodiment, the pseudo power failure mode is executed, and the power output from the power storage device 12 by the independent operation is supplied only to the audio equipment in the audio room 18 and connected to the general load 10 a and the important load 15. Not supplied to any electrical appliance. That is, the power supplied to the audio equipment in the audio room 18 is power with little voltage fluctuation.

  In this way, when the audio room 18 is normally used, the pseudo power failure mode is executed, whereby electric power with less voltage fluctuation is supplied to the audio equipment in the audio room 18 and the operation of the audio equipment is stabilized. As a result, the residents of the house can enjoy good sound.

  Next, a power supply mode in the power supply system 100 when the audio room 18 is not used during a power failure will be described with reference to FIG.

  In this case, power from the commercial power supply 90 is not supplied to the general distribution board 10 via the first power path 31. That is, power from the commercial power supply 90 is not supplied to the general load 10a.

  Further, in the third block B31, the second relay 17 is switched OFF, and the power cannot flow through the second relay 17. Further, when the second relay 17 is switched OFF in the third block B31, the fourth relay 21 included in the third block B31 is switched ON, and power can be distributed to the fourth relay 21. . Further, since the fourth relay 21 is also included in the second block B20, the fifth relay 22 included in the second block B20 is switched OFF, and power cannot flow to the fifth relay 22.

  In addition, when a power failure occurs, the power distribution through the second power path 32 is blocked by the interconnection breaker 13, and the power storage device 12 is disconnected from the commercial power supply 90. Thus, the power storage device 12 can perform a self-sustained operation, and the power charged in the storage battery 25 in the power storage device 12 can be output from the power conditioner 26. In this way, the power output from the power storage device 12 by the self-sustained operation is supplied to the important load 15 via the fifth power path 35 (fifth power branch path 35a) and the third power path 33.

  As a result, a resident of a house at the time of a power failure can operate an electric appliance connected to the important load 15, that is, a living room lighting, a medical device, a refrigerator, etc. The power output from the power storage device 12 can be used.

  As described above, since power is not allowed to flow to the fifth relay 22, the power output from the power storage device 12 by the independent operation is not supplied to the audio room 18.

As described above, the power supply system 100 which is an embodiment of the power supply system according to the present invention includes:
A general distribution board 10 for distributing the power supplied from the commercial power supply 90 to the general load 10a;
A power storage device 12 to which electric power from the commercial power supply 90 is supplied via the general distribution board 10;
The commercial power supply 90 is a power supply system in which the power storage device 12 is independently operated during a power failure and can supply power from the power storage device 12.
Comprising a first relay 14 that can be switched between ON and OFF, and that switches whether power is distributed from the general distribution board 10 to the power storage device 12;
When the first relay 14 is switched OFF at a normal time other than the time of the power failure, a pseudo power failure mode is executed in which the power storage device 12 is autonomously operated in a pseudo power failure state. is there.

  With such a configuration, it is possible to effectively use power with little voltage fluctuation.

In the power supply system 100,
An audio room 18 (dedicated load) different from the general load 10a;
When the simulated power failure mode is executed, power from the power storage device 12 is supplied to the audio room 18 (dedicated load), and power from the commercial power supply 90 is not supplied to the audio room 18 (dedicated load). Is.

  With such a configuration, it is possible to effectively use power with little voltage fluctuation in the audio room 18 (dedicated load).

In the power supply system 100,
An important load 15 that requires power supply even during the power failure and is different from the general load 10a and the audio room 18 (dedicated load);
A second block B20 (first switching block) capable of switching the power supply destination from the power storage device 12 to the audio room 18 (dedicated load) and the important load 15;
At the time of the power failure, the power supply destination from the power storage device 12 is switched from the audio room 18 (dedicated load) to the important load 15 by the second block B20 (first switching block).

  With such a configuration, it is possible to supply power from the power storage device 12 to the important load 15 with a simple configuration during a power failure.

  In the power supply system 100, the dedicated load is provided in an audio room 18 (acoustic space) having an acoustic device.

  With such a configuration, the operation of the acoustic device can be stabilized.

  Below, the structure of the electric power supply system 200 which is 2nd embodiment of the electric power supply system which concerns on this invention is demonstrated using FIG.

  In the power supply system 200 according to the second embodiment, the difference from the power supply system 100 according to the first embodiment is how to divide the three blocks regarding the control of the operation of each relay such as the first relay 14. . Hereinafter, the three blocks are referred to as a first block B11, a second block B21, and a third block B30, respectively.

  The first block B11 includes a first relay 14 and a fifth relay 22. In the operations of the first relay 14 and the fifth relay 22, exclusive control is performed such that when one is ON, the other is OFF.

  The second relay B21 is included in the second block B21.

  The third block B30 is the same as the third block B30 in the power supply system 100 according to the first embodiment.

  That is, the third block B30 is divided into a third block B31 and a third block B32.

  The third block B31 includes the fourth relay 21 and the second relay 17. As for the operation of the fourth relay 21 and the second relay 17, exclusive control is performed such that when one is ON, the other is OFF.

  The third block B32 includes the fifth relay 22 and the third relay 19. In the operations of the fifth relay 22 and the third relay 19, exclusive control is performed such that when one is ON, the other is OFF.

  Thus, the fifth relay 22 is included in both the second block B21 and the third block B30 (more specifically, the third block B32). The fourth relay 21 is included in both the second block B21 and the third block B30 (more specifically, the third block B31).

  Thus, when the operation of the first relay 14 and the fifth relay 22 is controlled in the first block B11, the operation of each switch in the third block B30 is controlled according to the control. Specifically, when the operation of the first relay 14 and the fifth relay 22 is controlled in the first block B11, the operation of the third relay 19 is controlled in the third block B32 of the third block B30. .

Below, the supply mode of the electric power in the electric power supply system 200 is demonstrated using FIGS. 6-9.
Note that the following description will focus on differences from the power supply system 100 according to the first embodiment.

  First, a power supply mode in the power supply system 200 when the audio room 18 is not used in a normal state will be described with reference to FIG.

  In this case, it is the same as that of the power supply system 100 according to the first embodiment, and power from the commercial power supply 90 is supplied to the general load 10 a and the important load 15. In addition, the power storage device 12 can be charged with power from the commercial power supply 90.

  Next, a power supply mode in the power supply system 200 when the audio room 18 is used in a normal state will be described with reference to FIG.

  In this case, in the first block B <b> 11, the first relay 14 is switched off, and power cannot flow through the first relay 14. That is, when the first relay 14 is switched to OFF, the power storage device 12 is disconnected from the commercial power supply 90 and enters a state in which power from the commercial power supply 90 cannot be supplied (a state during a pseudo power failure). The first relay 14 is switched from ON to OFF, for example, by a manual operation by a resident who uses the audio room 18.

  Thus, when the first relay 14 is switched from ON to OFF at normal times, the pseudo power failure mode is executed. That is, the power storage device 12 is operated independently, and the power charged in the storage battery 25 in the power storage device 12 can be output from the power conditioner 26.

  Further, when the first relay 14 is switched OFF in the first block B11, the fifth relay 22 included in the first block B11 is switched ON, and power can be distributed to the fifth relay 22. .

  Further, at the normal time, the fourth relay 21 included in the third block B31 is switched OFF, and power cannot flow to the fourth relay 21.

  In this way, the electric power output from the power storage device 12 by the independent operation is supplied to the audio room 18 through the fifth power path 35 (fifth power branch path 35b) and the fourth power path 34. Thus, a resident who uses the audio room 18 can enjoy the sound by operating the acoustic device using the power output from the power storage device 12 by the independent operation (that is, by effectively using the power with little voltage fluctuation). Can do.

  As described above, since power is not allowed to flow through the fourth relay 21, the power output from the power storage device 12 by the independent operation is not supplied to the important load 15.

  Next, a power supply mode in the power supply system 200 when the audio room 18 is not used during a power failure will be described with reference to FIG.

  In this case, when the control device 23 detects the occurrence of a power failure, the fourth relay 21 is switched ON in the second block B <b> 21, and power can be distributed to the fourth relay 21. Moreover, since the 4th relay 21 is also contained in the 3rd block B31, the 2nd relay 17 contained in the said 3rd block B31 will be switched OFF, and it will be in the state which electric power cannot distribute | circulate to the 2nd relay 17.

  Further, when the pseudo power failure mode is not executed at normal time, that is, when the first relay 14 is switched ON in the first block B11, the fifth relay 22 included in the first block B11 is turned OFF. It has been switched and power is not allowed to flow to the fifth relay 22.

  In addition, when a power failure occurs, the power distribution through the second power path 32 is blocked by the interconnection breaker 13, and the power storage device 12 is disconnected from the commercial power supply 90. Thus, the power storage device 12 can perform a self-sustained operation, and the power charged in the storage battery 25 in the power storage device 12 can be output from the power conditioner 26. In this way, the power output from the power storage device 12 by the self-sustained operation is supplied to the important load 15 via the fifth power path 35 (fifth power branch path 35a) and the third power path 33.

  As a result, a resident of a house at the time of a power failure can operate an electric appliance connected to the important load 15, that is, a living room lighting, a medical device, a refrigerator, etc. The power output from the power storage device 12 can be used.

  As described above, since power is not allowed to flow to the fifth relay 22, the power output from the power storage device 12 by the independent operation is not supplied to the audio room 18.

  Further, even during a power failure, the audio room 18 can be used with a simple operation. Specifically, as shown in FIG. 9, when the first relay 14 is switched OFF in the first block B11 from the state shown in FIG. 8, the fifth relay 22 included in the first block B11 is switched ON. In this state, electric power can be distributed to the fifth relay 22.

  In this way, the electric power output from the power storage device 12 by the self-sustained operation at the time of a power failure is supplied to the audio room 18 via the fifth power path 35 (fifth power branch path 35b) and the fourth power path 34. Thus, a resident who uses the audio room 18 can enjoy the sound by operating the acoustic device using the power output from the power storage device 12 by the independent operation even during a power failure.

  Note that if a power failure occurs while using the audio room 18 (during normal operation), the first block B11 is automatically controlled by the control of the control device 23 instead of being manually operated by a resident of the house. One relay 14 may be switched off.

  With such a configuration, a resident who uses the audio room 18 can operate the acoustic device using the power output from the power storage device 12 by the self-sustained operation without performing an operation when a power failure occurs. You can continue and enjoy the sound from the normal time.

  In addition, when setting it as such a structure, selection of whether operation | movement of an audio equipment is continued using the electric power output from the electrical storage apparatus 12 by independent operation using the display part 27 grade | etc., Of the control apparatus 23. It is desirable to notify the resident of information, information on the amount of power charged in the power storage device 12 (that is, a continuable period when the operation of the acoustic device is continued), and the like.

As described above, the power supply system 200 that is an embodiment of the power supply system according to the present invention is:
A fifth relay 22 (second relay) that can be switched between ON and OFF, and that switches whether power can be distributed from the power storage device 12 to the audio room (dedicated load);
The fifth relay 22 (second relay) is switched exclusively with the first relay 14.

  With such a configuration, it is possible to supply power from the power storage device 12 to the audio room 18 by a simple operation even during a power failure.

  Below, the structure of the power supply system 300 which is 3rd embodiment of the power supply system which concerns on this invention is demonstrated using FIG.

  In the power supply system 300 according to the third embodiment, the difference from the power supply system 100 according to the first embodiment is how to divide the three blocks related to the control of the operation of each relay such as the first relay 14. . Hereinafter, the three blocks are referred to as a first block B12, a second block B22, and a third block B32.

  The first relay B is included in the first block B12.

  The second block B22 includes the second relay 17 and the fourth relay 21. In the operations of the second relay 17 and the fourth relay 21, exclusive control is performed such that when one is ON, the other is OFF.

  In the second block B22, the second relay 17 and the fourth relay 21 are switched ON and OFF by the control device 23 when the control device 23 detects the occurrence of a power failure. Specifically, when the control device 23 does not detect the occurrence of a power failure, the second relay 17 is switched on and the fourth relay 21 is switched off (see FIG. 11). When the control device 23 detects the occurrence of a power failure, the second relay 17 is switched off and the fourth relay 21 is switched on (see FIG. 12).

  The third block B32 includes the third relay 19 and the fifth relay 22. In the operations of the third relay 19 and the fifth relay 22, exclusive control is performed such that when one is ON, the other is OFF.

  In the third block B <b> 32, the third relay 19 and the fifth relay 22 are switched ON and OFF by the control device 23 when the control device 23 detects the autonomous operation of the power storage device 12. Specifically, when the control device 23 detects a self-sustained operation of the power storage device 12, the third relay 19 is switched off and the fifth relay 22 is switched on (see FIGS. 11 and 12). Further, when the control device 23 does not detect the self-sustained operation of the power storage device 12, the third relay 19 is switched on and the fifth relay 22 is switched off (see FIG. 10).

Below, the supply mode of the electric power in the electric power supply system 300 is demonstrated using FIG.11 and FIG.12.
Note that the following description will focus on differences from the power supply system 100 according to the first embodiment.

  Next, a power supply mode in the power supply system 300 when the audio room 18 is used in a normal state will be described with reference to FIG.

  As shown in FIG. 11, when the audio room 18 is being used at normal time, the first relay 14 is switched OFF in the first block B <b> 12, and power cannot flow to the first relay 14. That is, when the first relay 14 is switched to OFF, the power storage device 12 is disconnected from the commercial power supply 90 and enters a state in which power from the commercial power supply 90 cannot be supplied (a state during a pseudo power failure).

  Thus, when the first relay 14 is switched from ON to OFF at normal times, the pseudo power failure mode is executed. That is, the power storage device 12 is operated independently, and the power charged in the storage battery 25 in the power storage device 12 can be output from the power conditioner 26.

  When the pseudo power failure mode is executed, the third relay 19 is switched off and the fifth relay 22 is switched on in the third block B32. Moreover, since the control apparatus 23 has not detected generation | occurrence | production of a power failure in normal time, while the 2nd relay 17 is switched ON in the 2nd block B22, the 4th relay 21 is switched OFF.

  In this way, the electric power output from the power storage device 12 by the independent operation is supplied to the audio room 18 through the fifth power path 35 (fifth power branch path 35b) and the fourth power path 34. Thus, a resident who uses the audio room 18 can enjoy the sound by operating the acoustic device using the power output from the power storage device 12 by the independent operation (that is, by effectively using the power with little voltage fluctuation). Can do.

  Note that, as described above, in the second block B22, power is not allowed to flow to the fourth relay 21, so that the power output from the power storage device 12 by the self-sustained operation is not supplied to the important load 15. The important load 15 is continuously supplied with power from the commercial power supply 90.

  Next, a power supply mode in the power supply system 300 when the audio room 18 is used during a power failure will be described with reference to FIG.

  As shown in FIG. 12, when a power failure occurs, the grid breaker 13 blocks the power distribution in the second power path 32, and the power storage device 12 is disconnected from the commercial power supply 90. Thus, the power storage device 12 can perform a self-sustained operation, and the power charged in the storage battery 25 in the power storage device 12 can be output from the power conditioner 26.

  Further, when the self-sustained operation is performed, the third relay 19 is switched to OFF in the third block B32 and the fifth relay 22 is switched to ON. Further, at the time of a power failure, since the control device 23 detects the occurrence of the power failure, the second relay 17 is switched OFF and the fourth relay 21 is switched ON in the second block B22.

  The electric power output from the power storage device 12 by the independent operation is supplied to the audio room 18 via the fifth power path 35 (fifth power branch path 35b) and the fourth power path 34. Thus, a resident who uses the audio room 18 can enjoy the sound by operating the acoustic device using the power output from the power storage device 12 by the independent operation (that is, by effectively using the power with little voltage fluctuation). Can do.

  Further, the power output from the power storage device 12 by the self-sustained operation is supplied to the important load 15 via the fifth power path 35 (fifth power branch path 35a) and the third power path 33. In this way, the resident of the house during a power failure can store the electrical appliances connected to the important load 15, that is, the living room lighting, medical equipment, refrigerator, etc., which are highly required to supply power during the power outage, through independent operation. The power output from the device 12 can be used.

  As described above, in the power supply system 300, the power from the power storage device 12 can be supplied to the important load 15 and the audio room 18 with a simple configuration even during a power failure.

As described above, the power supply system 300 according to the embodiment of the power supply system according to the present invention is
An important load 15 that requires power supply even during the power failure and is different from the general load 10a and the audio room 18 (dedicated load);
Whether or not power can be distributed from the commercial power source 90 to the important load 15 and whether or not power can be distributed from the power storage device 12 to the important load 15 is exclusive depending on whether or not the power failure occurs. A second block B22 (second switching block) for switching to
The second block B22 (second switching block) switches the distribution of electric power from the commercial power supply 90 to the important load 15 in the event of a power outage, and from the power storage device 12 to the important load 15. The power distribution is switched to be possible.

  With such a configuration, it is possible to supply power from the power storage device 12 to the important load 15 with a simple configuration during a power failure.

Further, in the power supply system 300, whether or not power can be distributed from the commercial power supply 90 to the audio room 18 (dedicated load), and the distribution of power from the power storage device 12 to the audio room 18 (dedicated load). A third block B32 (third switching block) that switches whether or not the power storage device 12 is independently operated depending on whether or not the self-sustaining operation is performed,
The third block B32 (third switching block) disables the flow of power from the commercial power supply 90 to the audio room 18 (dedicated load) when the power storage device 12 is operating independently. In addition to switching, the power distribution from the power storage device 12 to the audio room 18 (dedicated load) is switched.

  With such a configuration, power from the power storage device 12 can be supplied to the audio room 18 (dedicated load) and the important load 15 with a simple configuration in the event of a power failure.

The general distribution board 10 according to the present embodiment is an embodiment of the distribution board according to the present invention.
Moreover, the 1st relay 14 which concerns on this embodiment is one Embodiment of the 1st relay which concerns on this invention.
The fifth relay 22 according to this embodiment is an embodiment of the second relay according to the present invention.
The audio room 18 according to the present embodiment is an embodiment of a dedicated load according to the present invention.
Moreover, 2nd block B20 which concerns on this embodiment is one Embodiment of the switching block which concerns on this invention.

  The embodiment of the present invention has been described above, but the present invention is not limited to the above-described configuration, and various modifications can be made within the scope of the invention described in the claims.

  In this embodiment, the power supply systems 100, 200, and 300 are provided in a house. However, the power supply system according to the present invention is not limited to a house, but can be used in various buildings such as stores, office buildings, and condominiums. Can be adopted.

  In the present embodiment, the operation of each relay such as the first relay 14 (specifically, switching between ON and OFF) is performed under the control of the control device 23, but the present invention is not limited to this. Absent. For example, the operation of each relay such as the first relay 14 may be performed manually (manually) by a resident of a house. For example, the operation of each relay such as the first relay 14 may be automatically performed in response to detection of the breaker such as the interconnection breaker 13.

  In addition, the control device 23 according to the present embodiment may be configured by, for example, a home server (not shown), a control unit of the power storage device 12, a HEMS provided in a house, or the like.

  In the present embodiment, the audio room 18 is an embodiment of the dedicated load according to the present invention, but the dedicated load according to the present invention is not limited to the audio room 18. For example, the dedicated load according to the present invention may be any load that is desired to effectively use power with little voltage fluctuation, such as an electrical appliance such as a medical device.

  In the present embodiment, the power storage device 12 performs a self-sustained operation, but includes a transformer circuit, a frequency change circuit, and the like (not shown), and arbitrarily sets the voltage and frequency of power output from the power storage device 12 independently. It can be set as the structure which can be changed into. In this way, the power storage device 12 can supply electric power having an optimum voltage or frequency according to the acoustic device to a circuit provided in the audio room 18 and connected to the acoustic device. With such a configuration, the sound device can be operated using electric power having an optimal voltage and frequency, and a resident in the house can enjoy better sound.

  Thus, in the present embodiment, the power supply systems 100, 200, and 300 include the transformer circuit and the frequency change circuit that change the voltage and / or frequency of the electric power from the power storage device 12 output by the self-sustained operation. It is.

  With such a configuration, when using electric power from the power storage device 12 output by self-sustained operation, the electric power can be changed to an optimal voltage or frequency and used.

  In addition, the power supply system according to the present invention may have a configuration in which a power generation unit that generates power using sunlight, hydraulic power, wind power, tidal power, or the like, or a fuel cell is provided as natural energy.

  In the power supply systems 100, 200, and 300 as described above, if the output of power from the power storage device 12 continues excessively when the simulated power failure mode is executed, the amount of power charged in the power storage device 12 (Remaining capacity) may run out. Thus, when the remaining capacity of the power storage device 12 is exhausted, the power storage device 12 becomes an error and stops its operation. Therefore, in the power supply systems 100, 200, and 300, when the simulated power failure mode is executed, the output of power from the power storage device 12 (that is, the execution of the simulated power failure mode) is prevented from continuing excessively. Can have a configuration.

  In the present embodiment, the case where the output of power from the power storage device 12 continues excessively means that the output continues even though it is desirable to stop the output of power from the power storage device 12. It shall refer to the case. The state where it is desirable to stop the output of power from the power storage device 12 is, for example, when the resident has forgotten to end the pseudo power failure mode after using the audio room 18, or It is assumed that the remaining capacity is less than the amount suitable for discharge.

Below, the structure for suppressing that the output of the electric power from the electrical storage apparatus 12 continues too much is demonstrated using FIGS. 13-16.
In the following, for convenience of explanation, the power supply system 300 will be described as having the above-described configuration (configuration for suppressing excessive output of power from the power storage device 12). May have the above-described configuration. Hereinafter, the power supply system 300 having the above configuration is referred to as a “power supply system 400” as another example of the power supply system 300.

  13 to 15 show the configuration of a power supply system 400 as a first alternative example of the power supply system 300. As shown in FIG. 13, in the power supply system 400 according to the first different example, the difference from the power supply system 300 is that the lighting 10b, the sixth power path 36, and the sixth relay 24 are provided. The sixth relay 24 is included in the first block B12 (hereinafter referred to as “first block B14”) together with the first relay 14.

  The illumination 10b is lit in the audio room 18. The lighting 10b is included in the load at home (home load). The illumination 10b is distributed (supplied) with power from the general distribution board 10 via a sixth power path 36 described later.

  The sixth power path 36 is a path for distributing power. The sixth power path 36 is constituted by a conductive wire or the like. One side of the sixth power path 36 is connected to the illumination 10b. The other side of the sixth power path 36 is connected to the general distribution board 10. The sixth relay 24 is installed in the middle of the sixth power path 36.

  The sixth relay 24 switches whether power can be distributed. The sixth relay 24 is installed between the illumination 10 b and the general distribution board 10 in the sixth power path 36. When the sixth relay 24 is switched to ON, power can flow through the sixth relay 24. Further, when the sixth relay 24 is switched to OFF, electric power cannot flow through the sixth relay 24.

  The sixth relay 24 is linked to a lighting switch (not shown) that turns on / off the lighting 10b of the audio room 18. Specifically, when the illumination switch is turned on, the sixth relay 24 is automatically switched on, and the illumination 10b is turned on. When the illumination switch is turned off, the sixth relay 24 is automatically switched off and the illumination 10b is turned off.

  The first block B14 includes a first relay 14 and a sixth relay 24. In the operations of the first relay 14 and the sixth relay 24, exclusive control is performed in which when one is ON, the other is OFF. Here, the operation of the sixth relay 24 is interlocked with the illumination switch as described above. That is, the operation of the first relay 14 is also interlocked with the lighting switch in the same manner as the operation of the sixth relay 24.

Below, the supply mode of the electric power in the electric power supply system 400 which concerns on said 1st another example is demonstrated.
Note that the following description will focus on differences from the power supply system 300.

  First, the power supply mode in the power supply system 400 according to the first example will be described with reference to FIG. 14 when the audio room 18 is normally used.

  When the audio room 18 is normally used, the lighting switch of the audio room 18 is turned on by a resident to turn on the lighting 10b of the audio room 18. Thus, as shown in FIG. 14, when the illumination switch is turned on, the sixth relay 24 is turned on and the first relay 14 is turned off in the first block B14.

  When the first relay 14 is switched OFF, the pseudo power failure mode is executed. That is, the power storage device 12 is operated independently, and the power charged in the storage battery 25 in the power storage device 12 can be output from the power conditioner 26. Further, when the sixth relay 24 is switched ON, power from the commercial power source 90 (distributed by the general distribution board 10) is supplied to the illumination 10b.

  Thus, when the audio room 18 is normally used, the resident turns on the lighting 10b using the electric power from the commercial power supply 90 and uses the electric power output from the power storage device 12 by the self-sustained operation. You can enjoy sound by operating.

  Next, a power supply mode in the power supply system 400 according to the first different example when the use of the audio room 18 is finished from the state shown in FIG. 14 will be described with reference to FIG.

  When the use of the audio room 18 is finished, the lighting switch is turned off by the resident to turn off the lighting 10b of the audio room 18. Thus, as shown in FIG. 15, when the illumination switch is turned off, the sixth relay 24 is automatically turned off and the first relay 14 is turned on in the first block B14.

  When the sixth relay 24 is switched OFF, power is not supplied to the illumination 10b, and the illumination 10b is turned off. Further, when the first relay 14 is switched to ON, the pseudo power failure mode ends. That is, the self-sustaining operation of the power storage device 12 is stopped, and the power storage device 12 can be charged with power from the commercial power supply 90 by being linked to the commercial power supply 90.

  Here, when the use of the audio room 18 is finished, the lighting switch is turned off by a resident in order to turn off the lighting 10b of the audio room 18. That is, with such a configuration, even if the resident has forgotten to end the simulated power failure mode after using the audio room 18, the simulated power failure mode is turned on together with the lighting switch of the audio room 18 being turned off. Can be terminated.

  As described above, in the power supply system 400 according to the first alternative example, when the lighting 10b of the audio room 18 is turned off, the power storage device 12 is connected to the commercial power supply 90, thereby the commercial power supply 90 It is possible to charge the power. In this way, it is possible to suppress the output of electric power from the power storage device 12 from continuing excessively, and to prevent the power storage device 12 from stopping operation due to an error.

  Note that, in the power supply system 400 according to the first alternative example, the sixth relay 24 of the first block B14 is disposed in the middle of the path (sixth power path 36) through which power flows to the illumination 10b. In addition, although it is assumed to be interlocked with the illumination switch, it is not limited to this configuration. For example, the sixth relay 24 of the first block B14 is arranged in the middle of the path through which power flows to the audio equipment in the audio room 18 and interlocks with a power switch (not shown) of the audio equipment in the audio room 18 It is good.

  Here, when the use of the audio room 18 is finished, the power switch of the audio equipment in the audio room 18 is turned off by the resident. That is, with such a configuration, even when the resident has forgotten to end the pseudo power failure mode after using the audio room 18, the power switch of the audio equipment in the audio room 18 is turned off. The simulated power failure mode can be terminated. In this way, it is possible to suppress the output of electric power from the power storage device 12 from continuing excessively, and to prevent the power storage device 12 from stopping operation due to an error.

  Further, in the power supply system 400 according to the first alternative example, the first block B14 includes the sixth relay 24 together with the first relay 14, and the first relay 14 and the sixth relay 24 are exclusively controlled. However, the present invention is not limited to this configuration. For example, as shown in FIG. 16, the first block B <b> 14 includes only the first relay 14, and the first relay 14 is controlled in conjunction with a specific device (hereinafter referred to as “specific device 50”). It may be a thing. FIG. 16 shows a configuration of a power supply system 400 as a second example of the power supply system 300.

  The specific device 50 is a device provided in the house. In the present embodiment, for example, a human sensor (not shown) provided in the audio room 18, a timer switch, a HEMS (Home Energy Management System), or the like is assumed as the specific device 50. This will be described in more detail below.

  First, a configuration when the human sensor is used as the specific device 50 will be described.

  When there is a person in the audio room 18, the human sensor detects the presence of the person and outputs the detection result (detection result that there is a person in the audio room 18). The detection result of the human sensor is acquired by the control device 23. The control device 23 controls the operation of the first relay 14 according to the detection result of the human sensor.

  Specifically, in the first block B <b> 14, the first relay 14 is switched to OFF when a detection result that there is a person in the audio room 18 is output from the human sensor. In the first block B <b> 14, the first relay 14 is switched to ON when a detection result that there is a person in the audio room 18 is not output from the human sensor. Thus, the operation of the first relay 14 is configured to be linked with the detection result of the human sensor.

  Thus, when the resident enters the audio room 18, the detection result that there is a person in the audio room 18 is output from the human sensor, whereby the first relay 14 is turned off, and the pseudo power failure mode Is executed. That is, when the audio room 18 is normally used, the resident (in the audio room 18) operates the acoustic device using the power output from the power storage device 12 by the self-sustained operation to generate sound. I can enjoy it.

  When the use of the audio room 18 is finished, the resident leaves the audio room 18. In such a case, a detection result that there is a person in the audio room 18 is not output from the human sensor, the first relay 14 is switched on, and the pseudo power failure mode is terminated. That is, the self-sustaining operation of the power storage device 12 is stopped, and the power storage device 12 can be charged with power from the commercial power supply 90 by being linked to the commercial power supply 90.

  With such a configuration, even if the resident has forgotten to end the simulated power failure mode after using the audio room 18, the simulated power failure mode is terminated upon exit from the audio room 18. Can do.

  As described above, in the power supply system 400 according to the second alternative example, when there is no resident in the audio room 18, the power storage device 12 is connected to the commercial power supply 90, thereby generating power from the commercial power supply 90. Can be charged. In this way, it is possible to suppress the output of electric power from the power storage device 12 from continuing excessively, and to prevent the power storage device 12 from stopping operation due to an error.

  Although the detection result of the human sensor is assumed to be acquired by the control device 23, the detection result (output signal) of the human sensor is not transmitted to the first relay 14 without passing through the control device 23. It is good also as what is directly input and the operation | movement of the 1st relay 14 is controlled according to this.

  Next, a configuration when the timer switch is used as the specific device 50 will be described.

  The timer switch counts the time and outputs a signal indicating that the predetermined time has been reached when a predetermined time set in advance (for example, 7:00 am every day) is reached. The signal output from the timer switch is acquired by the control device 23. The control device 23 controls the operation of the first relay 14 according to the signal output from the timer switch.

  Specifically, in the first block B <b> 14, the first relay 14 is automatically (forced) switched on when a signal is output from the timer switch while being switched off. . Further, in the first block B14, when the first relay 14 is switched to ON and a signal is output from the timer switch, the switched to ON state is maintained. As described above, the operation of the first relay 14 is configured to be interlocked with the signal output from the timer switch.

  Thus, even if the resident has forgotten to end the simulated power failure mode after using the audio room 18, the first relay 14 is automatically switched on at 7 am every day, The power failure mode ends. That is, the self-sustaining operation of the power storage device 12 is stopped, and the power storage device 12 can be charged with power from the commercial power supply 90 by being linked to the commercial power supply 90.

  The predetermined time set in advance in the timer switch can be arbitrarily set by the resident according to the resident's lifestyle, the capacity of the power storage device 12, and the like. The predetermined time set in advance in the timer switch can be set as a time after a predetermined period from the time when the audio room 18 is once used (when the pseudo power failure mode is executed). Moreover, the device which time-measures whether it is the predetermined time set beforehand is not limited to a timer switch. Various commonly used devices can be used as the device for measuring whether or not the predetermined time is set in advance.

  In addition, the signal output from the timer switch is acquired by the control device 23, but the signal output from the timer switch is directly input to the first relay 14 without passing through the control device 23. The operation of the first relay 14 may be controlled accordingly.

  Next, a configuration when the HEMS is used as the specific device 50 will be described.

  The HEMS is included in the control device 23 in the present embodiment. The HEMS manages information in the power supply system 400 according to the second example, and controls each device constituting the power supply system 400. The HEMS grasps the energy usage status of each device constituting the power supply system 400, comprehensively grasps the energy demand and supply of the entire house, and controls each device to operate efficiently. can do.

  The HEMS acquires information related to the remaining capacity of the power storage device 12. The HEMS controls the operation of the first relay 14 in the first block B14 according to information on the remaining capacity of the power storage device 12.

  Thus, even when the audio room 18 is normally used, that is, even when the first relay 14 is switched OFF in the first block B14 and the pseudo power failure mode is executed, the remaining capacity of the power storage device 12 is maintained. In response to this, the first relay 14 is automatically switched ON. Specifically, when the remaining capacity of the power storage device 12 is equal to or less than a predetermined value (for example, a value of 10% with respect to the fully charged value), the first relay 14 is automatically switched ON, and a pseudo power failure The mode ends. That is, the self-sustaining operation of the power storage device 12 is stopped, and the power storage device 12 can be charged with power from the commercial power supply 90 by being linked to the commercial power supply 90.

  With such a configuration, even when the audio room 18 is being used at normal times, if there is a possibility that the remaining capacity of the power storage device 12 may be lost, the output of power from the power storage device 12 continues excessively. It is possible to prevent the power storage device 12 from stopping due to an error.

  When the remaining capacity of the power storage device 12 becomes a predetermined value and the pseudo power failure mode is automatically terminated, the remaining capacity of the power storage device 12 becomes equal to or lower than the predetermined value using the display unit 27 or the like in advance. The resident may be notified of this. With such a configuration, the occupant using the audio room 18 can recognize in advance that the pseudo power failure mode is finished (that is, the operation of the acoustic device is stopped).

  The HEMS acquires information related to the power consumption of the audio equipment in the audio room 18. Therefore, the HEMS may be configured to control the operation of the first relay 14 in the first block B14 according to the information regarding the power consumption of the audio equipment in the audio room 18.

  Specifically, when the power consumption of the audio device in the audio room 18 becomes a predetermined value (for example, the value of standby power) or less, it is considered that the operation of the audio device has ended. Therefore, when the power consumption of the audio equipment in the audio room 18 is equal to or less than the standby power value, it is not necessary to perform the self-sustained operation. Therefore, the first relay 14 is automatically turned on, and the pseudo power failure mode is set. It is good also as a structure made to complete | finish. The predetermined value can be arbitrarily set by a resident.

As described above, in the power supply system 400,
When the simulated power failure mode is executed,
When the predetermined condition is satisfied, the first relay 14 is automatically switched ON, and execution of the pseudo power failure mode is stopped.

  The timer switch (timer) for measuring time is provided, and the predetermined condition is satisfied when the time measured by the timer switch (timer) is, for example, 7 am (specific time). Is.

  With such a configuration, it is possible to prevent the power storage device 12 from stopping due to an error.

  Note that, in the power supply system 400 according to the first example, the lighting switch of the audio room 18 is turned off, or in the power supply system 400 according to the second example, the human sensor detects the audio room 18. The detection result indicating that there is a person inside is not output, the remaining capacity of the power storage device 12 becomes a predetermined value, and the like are examples of predetermined conditions for stopping execution of the pseudo power failure mode.
