摘　　要：对广州抽水蓄能B厂某发电电动机进行了三维涡流场有限元计算,建立了发电电动机的三维模型,分析了电流密度、磁密等场量的分布情况,获得了气隙径向磁密并进行了谐波分析。通过发电电动机的三维瞬态涡流场计算,可以更加准确地得到电机电磁场分布情况,运算结果能够为电机的设计、选型、国产化制造提供相应参考,在电机优化设计方面具有一定的参考价值。Pumped-storage power plant is extensively used in power system because of its ex- cellent performance in peak load and frequency regulation and emergency reserve. Generator-mo- tor is an important part of pumped-storage power plant and plays a key role in the operation of the whole power plant. Consequently, the safe and stable running of the power plant and even the power grid is directly influenced by the performance of generator-motor. This paper offers a 3-D transient eddy current field calculation on generator-motor of Guangzhou B pumped-storage power plant using finite element method. A 3-D generator-motor model is presented in this paper. The distribution of current density and flux density is educed, the radial air-gap flux density is ob- tained and the harmonic analysis is carried out. Through the calculation on 3-D transient eddy field of generator-motor, the distribution of motor electromagnetic field might be more accurately represented. The calculation result can offer reference for the design, model selection and local- ized manufacturing of motor.
