摘要

提出了一种输电线路故障行波网络定位新方法，采用邻近点优化策略算法求取故障行波最短传输路径，利用最短路径长度与传输时间呈正比例的关系，在直角坐标平面上对电网中各变电站记录的行波波头到达时间及传输距离进行直线拟合，通过线性回归分析实现各变电站行波到达时间的信息融合处理，从而直接得到故障点的准确位置。仿真分析结果表明，该方法能有效减少故障行波信号到达各变电站准确时间的记录误差，并提高故障定位的可靠性和精度。

Abstract

A new network-based algorithm for transmission line fault location with the traveling wave is proposed.The proximal point optimization strategy algorithm is used to find the shortest transmission path of the faulty traveling wave.The length of the shortest path is directly proportional to the transmission time.The linear fitting between the arriving time of the traveling wave head recorded by each substation and the transmission distance is made on the Cartesian coordinate plane.The information fusion for the traveling wave arriving time at each substation is achieved by linear regression analysis，and then the accurate location is obtained direct.The simulation results show that this method can effectively reduce the recording error in the arriving time of the faulty traveling wave at each substation while improving the reliability and accuracy of fault location.
