In order to simulate the common vibration fault of direct drive permanent magnet synchronous wind power generator (DDPMG) and traditional synchronous generator, puts forward a new diagnosis simulation research method of DDPMG based on spectrum analysis, changing the rotate speed of the generator to simulate the vibration of DDPMG by variable speed and frequency modulation device. It could effectively distinguish three different types of mechanical failures and located fault point. The experimental result shows that: ZonicBook 618E vibration tester simulates the DDPMG failure is veracious and effective.
