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。
Based on traveling wave theory of transmission line, a new method of fault location is proposed. The propagation delay of traveling wave with different moduli is used to construct the criterion of identifying the near-line and far-area faults of the line, and the influence of the traveling wave refraction wave front of the adjacent non-fault line is eliminated by approximate modulo velocity. Finally, the algorithm is given Optimization suggestions.
