摘　　要：本文采用节点数不多的热网络计算大型水轮发电机定子温度场,在电机设计或机组改造阶段,只要将数据输入微型计算机进行运算,便可预知发电机运行时定子内部的温度。本计算方法的优点是简单易行,内存少,运算时间短,具有足够的准确度和通用性。Here,the stator temperature field of hydrogenerator could be calculated by means of thermal network method with less nodes The calculated results can be getten only when putting the concerned data into mierocomputor at the design stage. Thus the advantages of this method are easy, less need of internal memories less of calculation time, high accuracy and can be used widely
