摘　　要：发电机的静态稳定边界点是进相试验的主要测定内容 ,也是关系其进相运行能力和实际运行中发电机组静态稳定性的决定因素。本文通过对水轮发电机派克方程和矢量图的分析 ,并考虑其在电力系统中的实际联结情况 ,建立一种精确的水轮发电机静态稳定边界计算方法———牛顿解析法 ,用此方法对多台机组静态稳定边界点所有参数的计算结果与试验实测值进行比较 ,误差很小 ,达到了足够的准确度。Static stability boundary point is a main part of leading phase test in generator and is the predominant factor that determines the leading phase operation capability and the static stability of the generator during operation.Basing on the analysis of Park model and the vector diagram of hydro generator and taking its actual wiring in the power system into account,this paper develop an accurate method—Newton analytical method,to calculate the static stability boundary condition.Comparison is made with this method between the calculated results and the measured results of all parameters of many units at static stability point.The error is small enough to meet the accuracy demand.
