摘　　要：利用二维静磁场有限元法分析设计兆瓦级直驱式永磁风力发电机,利用MATLAB/SIMULINK构建永磁同步发电机系统仿真模型,机侧变流器采用SVPWM可控整流方式。仿真结果表明所设计的发电机能够在额定转速下输出额定功率,交流电流波形正弦,证明该方法的有效性和正确性。The magnetic field and performance of megawatt direct-drive permanent magnet generator （DDPMG） for wind power systems were analysed by two dimensional finite element method.The DDPMG wind power system simulation model was built.The converter on machine side was controlled with SVPWM tactics.The simulation results show that the machine can run in rated power output at rated speed.And sinusoidal AC current waveform proves the validity and correctness of this method.
