摘　　要：本文首先用解析法推导了向心式磁极凸极同步电机的转子漏磁导的计算公式，然后介绍了这种漏磁导的有限元算法，最后说明了这种结构电机瞬态电抗和瞬态时间常数的计算，并以某电站的抽水蓄能电机为例进行了实算。The formula of the leakage permeance in rotor is deduced by analysis for large salient synchronous machine with radial pole, and the calculation of the permeance is introduced by finite element,then the calculation of transient reactance of the machine is explained. Finally, the permeance and the transient reactance are calculated taking a large pumped storage machine at a power station as an example.
