The most of generator synchronizing method is connect to the bus system with no load condition. but In case of parallel running with infinite bus system, sometimes we meet the synchronizing situation of loaded generator to the infinite bus. After the synchronizing to the bus, the frequency of generator system with no load has to be increased for the prevention of reverse power condition. But the frequency of generator system with load has to be lowered for prevention of load shifting to bus system. The black out of infinite bus decrease the generator's frequency of parallel running to infinite bus because of load increasing. This paper propose the method that the generator with loaded maintain the generator's frequency to the constant frequency after the black out of infinite bus. We use the constant speed control and load control method of parallel running system to the infinite bus. We apply the result to the industrial generating system.
