Abstract
随着继电保护对电网稳定运行的影响越来越大，继电保护定值的准确性也越来越重要，而在继电保护定值的计算过程中架空线路参数是非常重要的基础数据。本文针对传统计算法未考虑各杆塔接线形式导致计算结果不准确的问题，根据某调度继电保护处架空线路参数的计算方案，研究分析了其对各杆塔接线形式的处理以及对各段线路归属的处理，并提出了其存在的问题以及改进的思路。 As the relay protection effect on the stability of power grid is more and more big, the accuracy of the relay protection setting value is becoming more and more important. And in the process of relay protection setting calculation, overhead line parameters are very important basic data. Traditional calculation method, without considering the tower connection form leads to problem of inaccurate calculation results. This paper according to the overhead line parameters calculation schemes provided by a relay protection department, studied each tower connection form of processing and where each line belongs to, and put forward the existing problems and improvement ideas.
