摘　　要：基于三相PWM整流器的矢量控制原理,建立了网侧变换器输入电流控制所需的d-q模型,详细分析了交流励磁双馈风力发电系统网侧变换器的双闭环控制原理,提出了d、q轴电流的状态解耦控制策略,在此基础上研制了一套网侧变换器。实验表明,该变换器能够获得单位功率因数的正弦输入电流和稳定的直流输出电压,能够实现能量的双向流动,具有良好的动、静态特性。Based on the vector control principle, the d-q model is used to construct the converteri＇s input current, The dual-closeloop controller of the rectifier in the doubly-fed generating system is analyzed, the d-q model based on current state decoupling and grid voltage compensation control strategy is put forward to develop a grid-side converter, Sinusoidal input current with unit power factor, steady output DC voltage and fast dynamic response, as Well as bi-direction power flowing ability shown in the experiment show that the converter has excellent steady-state and dynamic performance.
