【Abstract】 On the basis of the equivalent system of single machine-infinite bus for 1250 MW 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 1250 MW 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.更多还原
