摘　　要：以恒速恒频风力发电机为对象,分析了其各个组成部分的动态模型,利用MATLAB/Simulink构建了其仿真系统模型。结合电力系统分析综合程序PSASP软件研究了风电机组不同风况和不同运行方式下对系统稳定性的影响。由仿真结果得出若采用X/R较小的联络线或适当提高电容器的补偿量,都有助于提高短路故障后风电系统的稳定性。Due to the grid-connected capacity of wind farm continuously increasing, adding the randomicity of its power, there is a important significance to study the effect of it combined to the network. Taking constant speed and constant frequency wind generator as object, we analyzed the dynamic model of its components and presented the model diagram of wind power units, using MATLAB/Simulink built its simulation systemic model. Combining Power System Analysis Soft Package（PSASP）, we studied the effect to systemic stability under different wind condition and operating mode. From the results of the simulation , we can conclude that if using linked line which has smaller ratio of x/r or increasing compensation quantity of capacitor suitably, the stability of system including wind power after occurring faults can be improved.
