摘要
分析2台站用变同时跳闸案例,得出站用变低压侧异常环网是导致跳闸的原因。使用Simulink进行仿真验证,仿真结果与实际结果相符。针对站用变低压侧异常环网的危害,提出了3条实用性强的应对措施。
The cases of simultaneous tripping of two stations are analyzed,and it is concluded that the abnormal ring network on the low-voltage side of the station is the cause of tripping.Simulink is used to verify the simulation,and the simulation results are consistent with the actual results.Aiming at the hazard of abnormal ring network on the low-voltage side of station,three practical countermeasures are proposed.
