Abstract
A system interconnecting facility is connected to a power system, and includes a plurality of power converters connected to the power system, a plurality of transformers provided between the power system and the power converters, a plurality of switches provided between the transformers and the power converters, and a controller that controls the opening and closing of the switch. The controller outputs, to the switches, open and close commands in so that the number of closed switches is out of a closed switch number range where a harmonic voltage of the system interconnecting facility increases, based on a harmonic voltage containing rate characteristic that is a relation between the number of closed switches and a harmonic voltage containing rate of the system interconnecting facility. The system interconnecting facility is capable of suppressing a harmonic voltage even if a circuit structure differs depending on a situation.
