在分析双馈风力发电机转子变流器运行特性的基础上，设计了该变流器的九点控制器。以8 kW双馈风力发电机为对象、Matlab为仿真工具，研究了在超同步转速、同步转速、低同步转速、大扰动等不同条件下该控制器的控制效果；在相同约束条件下，与传统PI 控制做了对比研究。仿真试验结果表明：九点控制器各项性能指标优于传统的PI控制器。

The nine-point controller of the rotor converter of double feed induction generator is designed based on the analysis of the features of doubly-fed wind power generator rotor converter. The control performance of the nine point controller under different conditions is studied, such as extra-synchronous revolving speed, synchronous revolving speed, low synchronous speed, and great disturbance etc., with 8 kW doubly-fed wind power generator as the object and Matlab as the simulation tools;the simulation results are compared between nine-point controller and the traditional PI controller under the same conditions. The simulation experiment data are showed that the performance indicators of nine-point controller are superior to the PI controller.
