The voltage harmonic is an important indicator to evaluate the power quality of PM wind generator. Voltage waveform is closely related to the degree of the air-gap magnetic field waveforms sinusoidal in the generator. Generator structure optimization can improve the degree of air-gap magnetic field sinusoidal, so it is an effective method to improve the quality of generator voltage waveform. This paper presents a pole width modulation method to reduce voltage harmonic of wind permanent magnet generator. The finite element analysis for traditional surface permanent magnet generator and a new very wide modulation permanent-magnet generator are done respectively. Then two...
