摘　　要：通过对风力机、双馈发电机建模,提出一种在双馈发电机转子侧采取基于定子磁链定向控制的策略。利用Matlab/Simulink平台,搭建系统仿真模型,对风机的最大风能点、转子电流等参数进行仿真。仿真结果表明,转子侧变流器控制策略有效可行,能在较短时间内实现最大风能跟踪,且转子电流能快速跟随风力的变化。With the continuous advancement of new energy technologies in China,wind power generation has developed rapidly,and its control strategy has become the focus of today's research.In this paper,a wind turbine and doubly-fed generator are modeled,and a strategy based on stator flux linkage control is proposed on the rotor side of the doubly-fed generator.Using the Matlab/Simulink platform,the system simulation model is built to simulate the maximum wind energy point and rotor current of the fan.The simulation results show that the rotor-side converter control strategy is effective and feasible,and the maximum wind energy tracking can be realized in a short time,and the rotor current can quickly follow the wind change.
