发电机定子接地保护的分析

Analysis on generator stator groud protection

本文介绍了发电机定子接地保护的种类、原理及应用以及对定子接地保护的要求,并针对发电机中性点接地方式的不同,具体分析了相应定子接地保护的原理、保护范围及配置特点,为其在大中型机组上安全有效的运行提供了重要的理论依据。最后介绍了孟加拉巴库现场定子接地保护的具体应用。

The kinds,the principle,the application and the request of the generator stator ground protection are represented in this paper.when the generator neutral terminal grounded in different way,the prinple,zone and configuration character are analyzed in this paper,which is an important basis in theory for its running safely and effectively in large and middle generating unit.in the end,we also introduce the actual application about generator stator ground protection in Bengal spot.
