摘　　要：建立了包括风速、风力机和风力机机械控制部分、变速恒频无刷双馈风力发电机的整体动态数学模型;应用MATLAB软件中的SIMULINK环境,以建立的数学模型为基础搭建了变速恒频无刷双馈风电机组仿真模型。以渐进风和随机风为例,对仿真模型进行分析。仿真结果表明了变速恒频无刷双馈风力发电机良好的运行特性及模型的正确性,并为无刷双馈电机在风力发电系统的进一步应用研究提供了可靠的理论依据。An overall dynamic model for variable speed brushless doubly-fed machine, including the wind speed, windturbine and control system of wind machine, is established. Based on the mathematic model, a variable--speed constant-frequency brushless doubly-fed generator （BDFG） simulation model is built by using SIMULINK of the MATLAR Then taking examples for ramp change of wind speed and random change of wind speed, the dynamic characteristics of BDFG is simulated. The results show the model is correct BDFG has good running characteristics and provide a credible foundation for further study on wind power system.
