POWER SUPPLY SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a power supply system capable of effectively using power with less voltage variation.SOLUTION: A power supply system capable of supplying power from a power storage device 12 performing autonomous operation at the time of outage of a commercial power supply 90 comprises a first relay 14 that is capable of being switched to ON or OFF to switch capability of a power flow from a general power distribution board 10 to the power storage device 12. A pseudo outage mode in which the autonomous operation of the power storage device 12 is performed in a pseudo state of outage time is executed when the first relay 14 is switched to OFF at normal time other than outage time.SELECTED DRAWING: Figure 3
