摘要

基于输电线路行波理论提出了一种故障测距的新方法。利用行波不同模量的传播时延构造出鉴别线路近区、远区故障的判据，并通过近似模速消除相邻非故障线路行波折射波头的影响，最后对算法的实施给出了优化建议。

Abstract

This paper presents a comprehensively improved fault location method based on the traveling wave theory of transmission lines. The proposed method takes advantage of different travel times of modal components for identifying close half and remote half faults. Approximate modulus velocity is utilized to eliminate the influences of refraction waves from healthy lines. Furthermore

suggestions to optimize the location calculation are also provided.
