摘要
根据双馈感应电机(DFIG)的数学模型,详细论述了双馈风力发电系统功率控制原理,分析了转子侧PWM变换器对定子输出功率的控制作用。转子侧PWM变换器采用按定子电压定向矢量控制策略,在实现定子输出有功、无功功率解耦控制的同时也能平滑地调节定子侧功率因数。MATLAB软件的仿真结果和所搭建双馈风力发电系统试验平台的试验结果均验证了控制方案的正确性和可行性。
Abstract： Based on the doubly-fed induction generator（DFIG） mathematical model, the power control theory of DFIG wind power generation system was discussed, and the control effect that rotor-side converter （RSC） acted on the output power of DFIG stator was analyzed. Then, a stator voltage orientation control strategy on RSC was derived to realize the decoupling control between active power arid reactive power in stator. At last, a simulation and experiment has been done to test and verify the decoupling control effect of the proposed control strategy.
