摘　　要：介绍开关磁阻风力发电系统组成;分析SRG的发电原理和非线性模型;针对小型风力发电系统运行速度低的特点,SRG采用电流斩波控制模式,电压反馈控制抑制输出电压波动;在Matlab中建立SRG电压反馈控制仿真系统,仿真结果验证了SRG建模的正确性,验证了SRG用于小型变速恒频风力发电系统的有效性。The simple composition of SRG wind power generating system was presented. The generation principle and the nonlinear model of SRG were studied. As the small wind energy applications were characterized by low-speed operation, SRG was controlled by current chopper, which used voltage feedback controller to minimize voltage ripples. In Matlab, the simulation model of SRG voltage feedback control system was established. The accuracy of SRG model and the validity of SRG for wind power generating system are testified by simulation results.
