摘　　要：基于SIMULNK技术,利用双馈感应发电机、风力机、电压型变流器、电压型逆变器的数学模型建立了相应的仿真模型;并对定子侧直接与50Hz电网连接,转子侧连接AC/DC/AC变流器的典型变速恒频风力发电系统进行了仿真验证。几个单独的风力发电系统子系统可以通过级联的方式构成大型风力发电场来模拟整个电网的运行情况。仿真结果表明.DFIG仿真模型的正确性和验证大型风电场的有效性。A DFIG consisting of a wound rotor induction generator and an AC/DC/AC IGBT-based PWM converter have been used for the simulation model of wind turbines based on SIMULINK technology. The stator winding is connected directly to the 50 Hz grid while the rotor is fed at variable frequency through the AC/DC/AC converter was built, and the control performance of VSCF wind power generation system with DFIG was simulated. The results showed that the DFIG can realize VSCF operation. Large-scale wind power plant consists of cascaded Individual wind power generation system. Validity of DFIG module is verified by simulation. The DFIG simulation module built can be used for simulation study on the DFIG and associated control system.
