摘要
接触网行波故障测距对保障电气化铁路安全畅通的运行具有很重要的现实意义。为了便于对接触网行波故障测距的学习,介绍了双端行波故障测距的原理和实现。根据T-R+NF供电方式利用ATP建立接触网模型,并通过MATLAB提取行波信号,寻找行波波头,最后利用行波到达两端的时间差,对故障进行较精确的定位。实践表明,双端行波故障测距极具可行性和有效性。
The catenary traveling wave fault location is very important to guarantee the electric railway operating smoothly and safely.In order to facilitate the study of traveling wave fault location,introduces the principle and realization of double terminal of traveling wave fault location.Using the ATP establish catenary model based on T-R＋NF,and extracted the traveling wave signal through MATLAB,through the lag of the head of the traveling wave reach on both ends,perform accurate positioning.Practice shows that double terminal method of traveling wave fault location is feasible and effective.
