摘要
从分析风力机运行特性出发,研究实现最优风能捕获的系统控制方法。并采用定子磁场定向的矢量控制技术,对双馈发电机转子进行交流励磁,实现发电机有功、无功及转速的独立控制,从而获得最大风能捕获的高效发电运行。仿真结果验证了文中所提出控制策略的正确性和有效性。
Based on analysis of wind power generator operation characteristics,system con trol method of capturing optimal wind energy is investigated. Stator flux orient ed vector control technology is used to execute AC excitation for doubly fed gen erator rotor, then independent control of active,reactive power and rotate spee d of generator is realized,electricity generation by capturing maximal wind ene rgy with high efficiency is also obtained. Simulation results are given to illus trate the correctness and feasibility of this proposed system control strategy.
