WIPO Patent Application WO/2022/102028
Kind Code:
A1
Abstract:
In a power conversion system (10) in one embodiment, a first power converter (11) is connected between a first AC power system (9) and a first DC main line (13A) as well as a DC return line (13B). A second power converter (12, 15) is connected between the first AC power system (9) and the DC return line (13B) as well as a second DC main line (13C). A first control device (33) controls the first power converter (11) according to a first active power command value. A second control device (34) controls the second power converter according to a second active power command value. A common control device (32) sets the first active power command value and the second active power command value by allocating all active power command values outputted from the entire power conversion system (10) to the first AC power system (9). The common control device (32) differentiates the first active power command value from the second active power command value.
