基于故障录波的发电机定子接地故障查找新方法

A new fault location method for stator single-phase ground fault in generator based on fault recorder

通过对发电机接地模型的分析计算,阐述了传统方法的局限性,并提出一种新的预估方法,即通过对分析故障录波信息对接地故障点进行准确预估。以实际接地故障为例进行实例分析,验证了所提出方法的正确性。

By analyzing and calculating the grounding model of generator,the limitation of the above mentioned methods is expounded,. And a new prediction method is put forward. Through analyzing the fault record information,the grounding fault location is accurately estimated in a real case.
