摘　　要：确定风力发电场的穿透功率极限是风电场规划和运行的一项重要内容。文章建立了考虑风电机组的叶片、轮毂、齿轮箱和联轴器的异步风力发电机组数学模型;给出了风电场输出功率计算方法;在此基础上,采用频率约束法求取风电场穿透功率极限,指出了频率波动是影响风电场并网运行的主要因素。The study of penetration limits of the wind farm is an important issue in the planning and operation of wind farm. Here, the mathematical model for asynchronous generator is estab- lished, which takes account of characteristics of the blades, hub, gearbox and shaft. The method which calculates output power of wind farm has been shown. The method of frequency restriction is used to calculate penetration limit of wind farm. The main factors influencing the interconnection of wind farm is frequency fluctuation.
