摘要：利用Ansoft软件中的Maxwell 2D模块建立了MW级双馈风力发电机（DFIG）的仿真模型。通过对DFIG模型进行静、瞬态仿真，得到它的磁力线分布图、磁密分布图、气隙磁密分布曲线、反电动势曲线，并对反电动势进行了谐波分析。仿真结果为双馈风力发电机的进一步优化设计提供了理论依据。

Abstract:A simulation model of doubly fed induction generator was presented using Maxwell 2D module of Ansoft. The distribution of flux linemagnetic，flux density，air gap magnetic flux density, back-emf curve, the back-emf curve were obtained by the static and transient simulation on the DFIG, And analyzed the back-emf harmonic.The results of simulation provided theoretical foundation for the optimization of DFIG.
