多支路发电机定子绕组接地短路点查找方法探索

Study on searching method for earth-fault of short circuit of multi-branch stator winding in generator

发电机定子绕组接地故障是一种常见的,破坏性很强的故障,对电厂发电机乃至电网的安全运行都将带来一系列严重的影响。本文通过对瀑布沟水电站1号水轮发电机定子接地短路故障点查找,探索出了一种在多支路发电机定子绕组接地时,快捷方便查找短路点的方法。

The earth-fault of short-circuit of stator winding in generator is a normal and strongly destructive fault which has a se- ries of significant impacts on generator in power plant and even on the safe operation of a power network.. Based on the search of the earth-faults of short-circuit of the stator in the No. 1 hydropower generator in Pubugou Hydropower Station, a quick and con- venient method for searching the short circuit fanlt occurred when the multi-branch stator winding of generator is earthed is found out herein.
