摘　　要：采用专业软件 Saber,结合 MAST 语言的编写,搭建了直驱式变速恒频风力发电系统的主电路模型和控制电路模型,并对该模型进行了仿真分析,分析结果说明了直驱式变速恒频风力发电系统的良好运行特性。另外,建模中根据仿真时间及仿真速度的要求,基于开关周期远小于仿真时间以及输出滤波器设计较好的假设,可在一定条件下忽略电力电子系统中开关作用的影响,建立该系统的平均模型,给出数值仿真结果,其仿真结果之间的比较验证了平均模型的可行性及有效性。Based on professional software Saber, combined with MAST language programming, main circuit model and control circuit model of direct drive variable speed constant frequency wind power system were established in the paper. The simulation results demonstrate the superior performance of direct drive variable speed constant frequency wind power system. Based on the assumption that switching period is much smaller than the simulation time and output filters are designed well, neglecting switching effort in power electronic system to some extent is an effective way if taking time and speed into consideration, then the average model of the system was derived. At last, the feasibility and validity of average model were verified through the comparison between simulation results.
