A system interconnection control section 7 interconnects and parallels off an output from a generator 1 with a system 9 , and supplies an output from the generator 1 to a load 10 . A selection switch 24 that selects operation modes of the generator 1 is provided. The operation modes are an interconnected operation mode to shut down operation of the generator 1 and an isolated operation mode to operate the generator 1 after disconnecting the output from the generator 1 from the system, when a power of the system 9 has been stopped. During a power failure, the selection switch 24 is switched to select a start and a shutdown of an isolated operation.
