摘　　要：推导了Ｅ＇ｑ恒定模型下发电机误同期合闸电磁转矩解析算式，分析了该模型下最大电磁转矩变化趋势。ln this paper, the analytical formulas of fault-synchronizing electromagnetic torque using constant model is derived. The trend of maximum electromagnetic torque is discussed according to the formulas. Finally, the analytical results are proved by digital simulation.
