摘　　要：分析了风力机的功率特性以及双馈感应电机的运行特性,探讨了最大风能追踪的控制策略,在定子磁链定向矢量控制策略下,基于S函数建立了双馈风力发电系统的仿真模型,并在两次阶跃风速下对所建模型的运行特性进行了仿真研究。仿真结果表明系统实现了最大风能追踪以及变速恒频运行,同时验证了所建模型以及控制策略的正确性。The operation principle of doubly-fed induction generator and the power characteristics of the wind turbine are analyzed,the control strategy of maximum wind energy tracking is discussed in detail,then the simulation model of doubly-fed wind power system is established based on stator flux orientation vector control strategy,taking two step-up wind speeds as example,simulation research is made on the operation characteristics of the model.The simulation results demonstrate that the model realizes the maximum wind energy tracking and variable-speed constant-frequency(VSCF) operation.At the same time,the simulation confirms the correctness of the model and the control strategy.
