| 摘 要： | 由于5号发电机及主变之间装有SF6开关，定子妆地保护在发电机启动和解列时经常误动。经查明，导致上述现象的原因是机组分布电容参数发生了变化。文中利用开关辅助接点投退该保护，只最根本的还是从保护整定方法和保护程序入手解决了该问题。

| Abstract: | Maloperation of generator stator ground protection based on the third harm onic in Manwan Hydropower Plant has occurred many times during generator starting and generator tripping.Through testing the sam e operating conditions as maloperation,the reason resulting in m aloperation has been found that the capacitance at the generator terminal is changed too large.This paper also proposes som e counterm easures for this purpose. |

| Keywords: | generator stator ground protection based on the third harmonic maloperation test countermeasure |
