随着长输电线路架设的越来越多，对故障后能够快速准确找出故障点的要求也越来越高，而在各种故障测距方法中，双端电气量法具有简单经济、精度高的优点。本文针对甘肃定西某调度单位基于整定计算软件研发的故障测距系统，研究了其故障测距算法及在发生故障时采取的措施，并提出了存在的问题及改进的思路。
The rapid and precise fault locating is now a high demand for the power grid with the growth of long transmission lines construction. Double Sides Electric Parameter method is a simple and economic method with high precision for fault locating. This paper studies the fault locating me-thod and corresponding procedures towards a fault locating system based on the setting calcula-tion software of a certain dispatch unit in Dingxi, Gansu, and proposes existing problems and im-provement ideas.
