  Hereinafter, a state in which power is distributed in the power supply system 1 configured as described above will be described. In the following description, the commercial power source 100 is not in a power outage (hereinafter simply referred to as “normal time”) and the commercial power source 100 is in a power outage (hereinafter simply referred to as “power outage”). Separately described.

  First, the normal operation will be described with reference to FIGS. In normal times, the switching unit 33 is switched to the first switching state.

  In normal times, the electric power from the commercial power source 100 is distributed by the first shared partial board 11 to the exclusive part 2a side (exclusive partial board 21) and the shared part 2b side (second shared partial board 12). . The power supplied from the first shared partial panel 11 to the dedicated partial panel 21 is supplied to the dedicated power load 22. A resident of each residence can use the exclusive power load 22 (lighting or the like) using the power.

  Further, the electric power supplied from the first shared partial panel 11 to the second shared partial panel 12 is supplied to the power supply control panel 13. The electric power is supplied to the common unit lighting fixture 15 and the common unit outlet 16 via the switching unit 33 and the branch breaker 35. In this way, the electric power from the commercial power source 100 can be used in the shared unit 2b.

  The power supplied to the power supply control panel 13 is supplied to the LED downlight 19 (exclusive outlet 18) and the USB outlet 20 via the switching unit 33, branch breaker 35, AC / DC converter 36, and DC / DC converter 17. Supplied to. Thus, after the electric power is once distributed to the exclusive part 2a and the shared part 2b by the first shared partial power board 11, the electric power distributed to the shared part 2b can be further supplied to the exclusive part 2a. Thereby, the power once distributed to the shared part 2b can be effectively utilized in the exclusive part 2a. For example, it becomes possible to use electric power (surplus power) that cannot be consumed by the shared section lighting fixture 15 and the shared section outlet 16 in the dedicated section 2a, and the electric power can be effectively used.

  At this time, the power that can be taken out from the dedicated outlet 18 and the USB outlet 20 to which power is supplied via the power supply control panel 13 (AC / DC converter 36) is equal to or less than a predetermined value (16 (W)). Is set to For this reason, it is possible to prevent the power from being excessively supplied from the power supply control panel 13 to a plurality of residences (a plurality of exclusive-use outlets 18 and the like).

  Furthermore, the LED downlight 19 connected to the exclusive outlet 18 consumes less power than an incandescent bulb or a fluorescent lamp. For this reason, it can prevent more effectively that electric power is supplied excessively from the electric power supply control panel 13 to a some residence.

  At this time, even if a loss occurs when AC power is converted to DC power in the AC / DC converter 36, the power from the AC / DC converter 36 is reduced by the LED downlight 19 or the USB with relatively low power consumption. It is supplied to the outlet 20. For this reason, it is difficult for a situation in which the power supplied to the LED downlight 19 and the USB outlet 20 is insufficient due to the loss in the AC / DC converter 36.

  The electric power supplied to the power supply control panel 13 is supplied to the power storage device 14 via the input side breaker 31. The power storage device 14 charges the power at an appropriate timing. For example, by charging relatively inexpensive power such as midnight power, the power can be effectively used later.

  Next, the power failure will be described with reference to FIGS. 1 and 4. During a power failure, the switching unit 33 is switched to the second switching state.

  At the time of a power failure, power is not supplied from the commercial power source 100 to the first shared partial panel 11. Accordingly, power is not supplied from the first shared partial panel 11 to the dedicated partial panel 21, and the dedicated power load 22 (such as lighting) connected to the dedicated partial panel 21 is used. I can't. Similarly, at the time of a power failure, power is not supplied from the first shared partial panel 11 to the power supply control panel 13 via the second shared partial panel 12.

  At the time of a power failure, the power storage device 14 performs discharging (independent output). Specifically, the power storage device 14 supplies power to the switching unit 33. The electric power is supplied to the common unit lighting fixture 15 and the common unit outlet 16 via the branch breaker 35. Thus, at the time of a power failure, the common part lighting fixture 15 can be turned on using the electric power from the electrical storage device 14, or the electric power can be taken out from the common part outlet 16.

  The electric power supplied from the power storage device 14 to the switching unit 33 is supplied to the LED downlight 19 and the USB outlet 20 via the branch breaker 35, the AC / DC converter 36 and the DC / DC converter 17. Thus, at the time of a power failure, the electric power from the electrical storage apparatus 14 can be supplied to the exclusive part 2a. Thereby, the resident of each residence can use electric power even at the time of a power failure.

  Further, even during a power failure, it is possible to prevent excessive power from being supplied from the power supply control panel 13 to a plurality of residences (such as a plurality of dedicated outlets 18) in the same manner as during a normal power outage. Thereby, especially at the time of a power failure, it is possible to prevent the electric power stored in the power storage device 14 from being rapidly reduced, and as a result, it is possible to reliably distribute the electric power to all the plurality of houses.
