摘要

本文提出了用准三维正弦磁场有限元法计算大型汽轮发电机定子端漏电抗的方法，并推导了定子端漏电抗的计算公式。以600mw汽轮发电机组为例，讨论了端部涡流、定子铁芯长度等因素对机组性能的影响。

Numerical calculation of stator end-leakage reactance of large turbogenerator

In this paper, the method of calculating stator end-leakage reactance of large turbogenerator by quasi-3D sinusoidal magnetic field FEM is presented, and the formula of stator end-leakage reactance is derived. Taking the 600 MW turbogenerator as an example, the influence of some factors such as the eddy current in end parts and the length of stator and rotor iron core are discussed.
