Document Type and Number:
Japanese Patent JP2022128198
Kind Code:
A
Abstract:
To reduce the possibility that a switching operation of a switch is not properly performed.SOLUTION: A power switching system 10 comprises a switch 5, a first operation unit 6, a second operation unit 7, a voltage detection unit 12, and an inspection unit 8. The switch 5 performs switching operation of connection between a system power supply PS1 and a distributed power supply system 2 that has a distributed power supply (a solar battery PV1) that can be interconnected with the system power supply PS1. The first operation unit 6 controls state of connection between the system power supply PS1 and the distributed power supply system 2. The second operation unit 7 controls state of connection between the distributed power supply system 2 and the system power supply. The voltage detection unit 12 detects each voltage of a power supplied form the system power supply PS1 and power supplied from the distributed power supply system 2. The inspection unit 8 inspects whether or not the switching operation by the switch 5 is normal on the basis of the voltage detected by the voltage detection unit 12.SELECTED DRAWING: Figure 1
