基于WSN技术提出一种改进的DV-Hop算法解决配电线路故障定位不准确的问题.阐述了配电线路WSN故障定位原理,针对配电线路的实际特性,建立无线传感器节点拓扑模型.分析了传统DV-Hop算法应用到配电网中的缺陷,同时对其进行改进.MATLAB仿真结果表明,改进的DV-Hop算法应用于配电线路故障定位的误差率明显低于传统定位算法,此外,误差曲线也更加稳定,能够达到更高的定位精度,更加适合配电线路上的故障位置节点定位.

Based on the technology of WSN,an improved DV-Hop algorithm has been proposed to solve the deficiencies of fault location on distribution line.This paper discussed the principle of WSN fault location on distribution line.Aiming at the actual characteristics of distribution line,the topological structure of wireless sensor nodes has been established.This paper also and analyzed the defects when the traditional DV-Hop algorithm applied to distribution network,and improved the work at the same moment.Simulation studies using MATLAB show that the error rate of the improved DV-Hop algorithm is obviously lower than that of the traditional localization algorithm when they are used in fault location on distribution line.In addition,the error curve is relatively more steadily.The improved algorithm can achieve higher localization accuracy,so it is more suitable for fault location on distribution line.
