摘　　要：建立了汽轮发电机端部三维电磁场的数学和物理模型,采用二维和三维磁场耦合的方法确定边界条件,对汽轮发电机端部电磁场进行计算。采用能量法对定子端部漏抗的计算公式进行推导,并以QF-150-2型发电机为例,对定子端部漏抗参数进行了计算,分析了端部结构件中的涡流对定子漏抗参数的影响。The mathematical and the physical model to calculate stator end-leakage magnetic field of large turbogenerator are presented. With combined 2D and 3D magnetic field method, the boundary condition is determined and the formula of stator end-leakage reactance is derived. Taking QF-150-2 turbogenerator for example, the stator end-leakage reactance is calculated and the influence of eddy current is discussed.
