Title:
POWER CONTROL SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/148936
Kind Code:
A1
Abstract:
A power control system (10A) comprises: a first energy storage system (21); a bidirectional AC/DC converter (20) that is connected between an AC power system (15) and the first energy storage system (21); and a control device (22) that controls operation of the bidirectional AC/DC converter (20). The control device (22) controls charging/discharging of the first energy storage system (21) by controlling the operation of the bidirectional AC/DC converter (20). The power control system (10A) further comprises: a circuit breaker (33) that is connected between the AC power system (15) and the bidirectional AC/DC converter (20); a resistor (31) that is connected between the circuit breaker (33) and the bidirectional AC/DC converter (20); and a switch (34) that, in a state where the circuit breaker (33) is open, forms a discharge path for discharging the DC power of the first energy storage system (21) via the resistor (31).
