摘要
对三种不同原理的发电机定子接地保护 :基波零序过电压保护、三次谐波电压单相接地保护以及外加 2 0Hz交流电源式 1 0 0 %定子绕组单相接地保护在现场的应用进行了分析 。
Summary:This text analyse three kind of different stator ground protections,namely.Base protect by wave 50Hz;In harmony wave voltage single-phase ground protection three times;Plus 20Hz exchange power type 100% stators of single-phase ground protection of winding.And personal opinion these stator pretections are put forward.
