摘　　要：基于1250MW核电半速汽轮发电机单机无穷大等值系统,建立了机网动态分析的场–路–机–网耦合时步有限元仿真模型。采用建立的模型对1250MW核电半速汽轮发电机误同期并网工况进行了仿真,获得了机组电气量、机械量及电机内电磁量的变化规律,仿真结果表明建立的模型正确,为电机优化设计及机组安全稳定运行提供了理论参考。On the basis of the equivalent system of single machine-infinite bus for 1250MW half-speed turbo generator, the field-circuit-mechanical system-network coupled time-step finite element model for dynamic analysis of machine-network was set up. Faulty synchronization of 1250MW half-speed turbo generator was simulated with the field-circuit-mechanical system-network coupled model, and the electric, mechanical and electromagnetic variables were obtained. The simulation results show that the coupled model set up in this paper is correct and provide reference for optimizing design and operating safely of half-speed turbo generator.
