摘要

针对某110kV变电站Ⅰ号电容器投运以来保护频繁动作

结合电容器内部结构和保护动作机理

详细分析了该组电容器保护频繁动作的原因

并针对电容器保护定值设置提出了相关建议

调整保护整定后

运行至今未发生保护动作

验证了分析的正确性。

Abstract

As for frequent protection action of No.1 capacitor at a certain 110 kV substation and in combination with internal structure and protection action principle of the capacitor

the reason on frequent action of the capacitor bank protection is analyzed in detail

and related suggestions on the set-up of protection setting of capacitor are proposed.The results show that the analysis is correct and the measures are effective.
