Title:
WIND POWER GENERATOR VIBRATION INHIBITION METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/188069
Kind Code:
A1
Abstract:
A wind power generator vibration and noise inhibition method and device. The method comprises: calculating to obtain a setpoint value of a flux-weakening control parameter of a generator according to the setpoint value of an electromagnetic active power of the generator and a frequency of the generator (S101); and controlling the generator according to the setpoint value of the flux-weakening control parameter of the generator (S102). The method and device reduce the magnetic load of the generator by the flux-weakening control, thereby inhibiting vibration and noise of the generator.
