Halbach阵列在直驱、半直驱风力发电机的应用
Application of direct-driven and half-direct-driven wind power generators based on Halbach
摘要
Abstract
This paper propose a Halbach array that be used in direct-driven and half-direct-driven wind generator for reducing the mass of wind power generator.These generators have characteristics of simple structure,low maintenance cost,small diameter,small mass,low vibration and noise,which made it is very suitable for electricity generation at low wind speed.The FEM analysis is used in modeling of the 1.5 MW direct-driven and the 1.5 MW half-direct-driven permanent magnet synchronous wind power generators,and then simulating models by comparing the performance of air gap flux density under different pole pairs,air gap length,the size of the motor.To extract the fundamental and harmonic content of air-gap flux density by using Fourier transform,the static magnetic field of the generator based on Halbach array is analyzed and compared.The simulation results show that the generators based on Halbach array have less harmonic content,higher air gap flux density and the waveform closer to the sine wave and excellent performance when the number of poles are between 70 and 90.关键词
