Abstract
A vibration suppression method and device of a wind power generator is provided. The method includes: calculating a specified value of a flux-weakening control parameter of the generator according to a preset value of an electromagnetic active power of the generator and a frequency of the generator; and controlling the generator according to the specified value of the flux-weakening control parameter of the generator. The method and device reduce the magnetic load of the generator by the flux-weakening control, thereby suppress vibration and noise of the generator.
