中文摘要：

随着风力发电装机容量的不断增大,风电在电网中所占比重也越来越高,这就要求并网风电系统应具有一定的稳定性。以典型单机无穷大系统为思想基础,提出了基于潮流极限的系统静态功角稳定性分析的方法,应用在张家口某一区域电网中。通过对该系统的仿真和研究,表明了该方法可有效地分析并网风电系统的静态功角稳定性和稳定裕度问题。

英文摘要：

With the increasing of installed wind power capacity, the proportion of wind power in the grid is also growing, which requires that wind power system should have a certain degree of stability. With the typical single machine infinite bus system as the ideological basis, the system based on the trend of the limits of static angle stability analysis method used in Zhangjiakou, a regional power grid was proposed. The system simulation and research results show that this method can effectively analyze grid wind power system static angle stability and stability margin.
