摘要

分析了 10 0 %定子接地保护外加电源的频率对保护灵敏度的影响及其导致 10 0 %定子接地保护拒动的原因。此外还分析了特殊工况下

定子电流频率与 10 0 %定子接地保护误动的关系。并针对这两种情况分别提出了解决方案。

Abstract

The effect of the frequency of applied power source for protection against stator ground 100% on protection sensitivity and the reason caused the miss operation of protection against stator ground 100% have been analyzed. Besides

the relationship of stator current frequency and miss operation of protection against stator ground 100% in exceptional condition has been analyzed as well

and solutions corresponding to these two conditions have been proposed respectively.
