摘　　要：为了消除PWM脉冲死区时间对双馈风力发电机在低转速时的性能影响,提高风力机在低风速时向电网输送的电能质量。提出了应用Motorola DSP56F807对SVPWM死区时间的补偿方法,并详细介绍了其补偿原理以及软件实现。最后通过背靠背测试平台(back-back test bench)验证了方法的正确性。In order to eliminate impact inducing from the PWM dead time on performance of the doubly-fed induction generator at low speed and improve the power quality supplied by the doubly-fed induction generator, the compensation methods of the SVPWM dead time based on the Motorola DSP56FS07 is presented in the paper, and describes in detail its compensation principle and software realization. Finally, the correctness of the proposed methods is verified through back-to-back test bench.
