PROBLEM TO BE SOLVED: To make a system be flexible, and maintain continuous operation of the system even when a device for transmitting a synchronous signal stops unexpectedly.SOLUTION: A controller of a power converter comprises: a communication unit for communicating with controllers of one or more other power converters for outputting power to a power line; a synchronous signal unit for receiving a synchronous signal to be reference of a phase of output power of the power converter; a power phase control unit which controls the phase of the power output to the power line by the power converter on the basis of the synchronous signal, and, when detecting interruption of the synchronous signal, controls the phase of the power output to the power line by the power converter on the basis of a synchronous signal received before the interruption; and a communication control unit for controlling the communication unit so that the communication unit performs either of reception and transmission of information for determining a master for transmitting the synchronous signal, during the control by the power phase control unit on the basis of the synchronous signal received before the interruption. |
