电力系统接地距离保护零序补偿系数分析

Analysis of Zero-Sequence Current Compensation Coefficen t for Ground-fault Distance Protection in Power System

本文主要分析讨论接地距离保护在有零序互感线路上应用的一些特殊问题，尤其对零序补偿系数的不同情况进行了分析。详细推导了不同运行条件下零序互感耦合线路的零序补偿系数的计算公式，并附有实例对各种运行情况进行比较，确定在整定计算中采用的算法。

In this paper,some special problems of ground-fault distance protection for zero-sequence mutual inductance lines are pro-posed. A zero-sequence current compensation coefficient of ground-fault distance protection is discussed especially. Calculating formulas and exampls are shown in the paper. algorithm of relay settings is prosented.
