摘　　要：根据双馈风力发电系统的特点,采用矩阵变换器作为其交流励磁调节装置,结合定子磁链定向控制策略,建立了变速恒频风电系统控制模型。为提高风力发电系统的效率,提出一种无需检测风速和功率信号且算法较为简单可靠的最大风能捕获方法。利用Matlab/Simulink对亚同步速、同步速、超同步速3种典型工作状态下的运行特性进行仿真分析。结果表明,该方法实现了有功、无功功率的解耦控制和最大风能的捕获控制。According to the characteristics of doubly-fed induction generators （DFIG） wind energy generation power control system, matrix converter is used as the AC-excitation controlling device.Combined with the stator flux oriented vector control strategy,experimental model of the variable-speed constant-frequency wind generation system is established.In order to improve the efficiency of wind generation system, a simple and reliable control algorithm of the maximal wind energy capture is proposed, which makes the system operation without wind speed or electrical power measurement.The operational performances of doubly-fed wind power generation system, which including three classical work modes of sub-synchronous, synchronous and super-synchronous are emulated by using Maflab/Simulink.The resuits show that the decoupling control of active and reactive power of DFIG can be implemented, which finally reaches the control of the maximal wind energy capture.
