摘　　要：由双馈发电机q-d坐标系下基本数学模型,推导出双馈发电机的转子电流和转子电压、磁链之间的关系模型。文章研究了双馈风力发电系统转子侧电流控制策略框图,计算选择PI控制器参数。利用MATLAB/SIMULINK平台自行建立了1.5 MW风力发电系统整体仿真模型。运行该系统模型,得到了双馈发电机转子电流、电压,滤波器输出电流及定子电压等信号波形曲线。仿真结果验证模型及控制器的正确性,证明PI控制器能够满足双馈风力发电系统的稳、准、快等性能指标。The relational model among rotor currents,rotor voltages and flux for double-fed generator is derived from the basic mathematical model of the generator’s d-q reference frame.The current control strategy block diagram of rotor side in the doubly-fed induction wind generators system is studied,then PI controller parameters are calculated and chosen.Based on MATLAB/SIMULINK platform,the simulation model for wind turbine generators system of 1.5MW is built the whole system simulation model.By running the model,the DFIG rotor currents,voltages,filter currents and stator voltages waveform are gained.The verification model of simulation results and the validity of controller prove that the PI controller can meet the performance index of the DFIG for wind power system,such as system stability,rapidity and accuracy.
