摘要

通过计及与不计及电容器组故障相电抗率变化对不平衡保护定值影响的比对

得出两者计算结果在电容装置工程实用范围内近似等效的结论

从而为采用不计及影响的“简化计算”提供可行的佐证。

Abstract

By comparing the setting calculation of protection considered with or without the variation of the reactance ratio of the fault phase capacitor bank

get the conclusion that the result of the setting calculation is approximate equivalent within engineering application accuracy

and provide an evidence for the "simple calculation equation " considered without the influence of the variation of the reactance ratio.
