摘　　要：针对双馈风力发电机组,首先建立基于电功率的电磁转矩计算模型,然后将风力发电机叶片、低速轴、齿轮箱、高速轴、转子组成的旋转系统等效为二质量块-弹簧模型以建立风力机传动链等效模型,最后建立3种传动链扭矩逆模型并仿真比较其优缺点。Drive train torque as one of wind turbine load is the base to establish the MIMO model for individual blade pitch control. The electromagnetic torque calculation model based on electric power, as well as the two-mass torsional model, including the blades, low speed shaft, gear box, high speed shaft and generator was established. The torsional torque and the wind turbine torque were calculated based on the model. The simulation results indicated that the torsional torque calculated by the model is consistent with the theoretical value, which is the foundation to further realize the application of individual blade pitch control.
