摘要
单端法是行波测距研究的热点问题,讨论了输电线路故障时暂态行波的产生及在线路上的传输过程,在此基础上通过检测突变点模极大值的方法确定故障发生的时间。并通过MATLAB仿真表明此理论和测距方法在不同线路模型故障测距中是正确和有效的。
The single-ended method is hot issue in the research of traveling wave fault location. The production and transmission of transient traveling wave on transmission line is proposed. The fault occurred time is determined through test mutations point modulus maxima method. It is shown that the theory and method applied in different transmission line model fault location is valid and effective by Matlab simulation.
