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)验证了该方法的正确性。
In order to eliminate impact inducing from the PWM dead-time on performance of the doubly-fed in- duction generator at low speed and improve the power quality supplied by the doubly-fed induction generator, the compensation methods of SVPWM dead-time based on DSP56F807 is presented. The compensation principle and software realization are described in detail. Finally ,the correctness of the proposed methods is verified through back-to-back test bench.
