【摘要】 对同步电动机群中单台同步电机异步起动时对电网及同步电动机群造成的过渡过程进行了仿真分析 .从同步电动机的电磁关系、电压特性、功角摇摆及其稳定性方面系统地分析了一台同步电动机异步起动导致整个电动机群的扰动 ,以及正常电机与起动电机间的相互影响 ,并得出了一些有用的结论 .在仿真过程中 ,考虑了饱和和阻尼转矩的影响 ,以使结果更加与实际相符更多还原

【Abstract】 This paper presents the simulation of the transient performance of synchronous motors when one synchronous motor was asynchronous direct-on line starting.The simulation in various conditions was calculated.The analysis of the disturbances of all motors caused by the starting and interference between the running of the normal and the starting was conducted from the point of their electromagnetic relation and voltage characteristic,power-angle swing and stability.Some conclusions were drawn.The magnetic saturation and damping torqe were also taken into account during the simulation.更多还原
