摘　　要：凸极同步发电机的静态稳定边界点是其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.通过对水轮发电机派克方程和矢量图的分析,并考虑在电力系统中的实际连接情况,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,此方法应用于多台发电机组的进相试验,其静态稳定边界点所有参数的计算结果与试验实测值相比较,误差很小,达到了足够的准确度,可作为发电机组进相运行静态稳定性计算与分析的方法.It is the main purpose to get static stable boundary in the test of leading power factor operation for hydro generator due to its importance for the static stability to put in operation． After studied on the Park equations and vector figure with attentions about the generator＇s real connection in the power system, a precise method to calculate the static stable boundary of the hydro generator is established which called Newton method． This was used in some tests and it was found that the errors between the calculation and the testing result are a little．
