摘要 基于变速恒频双馈式风力发电机定子磁链定向控制理论,提出了交流励磁电源的控制方案。控制结构采用双PWM变换器结构,变换器的控制采用了基于矢量控制技术的解耦控制策略,并在实验室完成了最终的亚同步、超同步运行实验,以及在模拟风速变化的情况下系统的有功、无功解耦控制实验。实验结果验证了该方案的可行性。 Based on the oriented control theory of variable speed constant frequency doubly fed induction generator's stator flux,this paper presents a AC-supply control strategy.The control scheme adapts back-to-back PWM converters whose decouple control strategy based on vector control technology.Finally,the system experiment under sub-synchronization and super-synchronization condition is completed, and the system active and reactive power decoupled simulant experiment under variable wind speed condition is also completed.The experimental results validate the feasibility of the control scheme.
