摘要

为实现输电线路单相断线故障的快速精准定位, 缩短供电恢复时间, 提出了一种基于OPGW光传感技术的光偏振态故障定位方法。根据法拉第磁光效应的原理, 以光纤复合架空地线(OPGW)为传感器, 通过自制设备捕获和分析输电线路相导线对 OPGW产生的感应电流在单相断线瞬间的突变信号, 实现对故障点的定位。在实验环境下进行模拟实验对其验证, 结果表明: 在给定的电流范围内, 设备获取的信号强度与导线通电电流大小呈正相关, 设备能有效捕捉线路断电瞬间的突变信号, 实现故障点定位, 定位结果误差在±250 m内, 满足工程设计的要求。

Abstract

In order to achieve fast and accurate location of single-phase disconnection fault on transmission lines, shorten the power recovery time, a new fault location method based on optical polarization of OPGW optical sensing is proposed. According to the principle of Faraday magneto-optical effect, the optical fiber composite overhead ground wire (OPGW) is used as a sensor to capture and analyze the abrupt signal of the induced current generated by the phase conductor to the overhead ground wire before and after the single- phase wire breakage fault. The location of single-phase disconnection fault is realized. The experiment in the experimental environment is simulated to verify it. The results show that within a given current range, the current intensity obtained by the device is positively correlated with magnitude of the current, the device can effectively capture the abrupt signal at the moment of power failure, and the location result error is within ±250 m, which meets the requirement of engineering design.
