摘要

为了提高输电线负载能力、防止电网事故发生，文章利用布里渊散射和相干检测的原理，设计了一种基于自发布里渊散射的架空输电线路弧垂在线监测系统。利用布里渊光时域反射（BOTDR）技术，实时采集沿光纤分布的应变信号，提取应变传感关键性特征，实现对弧垂异常点的精准定位和预警。实验室数据和变电站测试结果表明：系统能够实时检测和精准定位应变变化信息，可单端测量且操作简单；可精准定位应变突变点，实现电缆弧垂异常情况的预警，及时发现和处理故障隐患，保证输电线路的安全稳定运行。

Abstract

To improve transmission line load capacity and prevent power grid accidents

an online sag monitoring system for overhead transmission lines based on spontaneous Brillouin scattering is designed using the principles of Brillouin scattering and coherent detection. Brillouin Optical Time Domain Reflection (BOTDR) technology is used to collect the strain signal distributed along the optical fiber in real time

extract the key features of strain sensing

and realize the accurate positioning and early warning of sag anomaly points. Laboratory data and substation test results show that the system can detect and accurately locate strain change information in real time. The strain monitoring system is simple in single-end measurement and can accurately locate the strain mutation point. It can realize the early warning of cable sag abnormalities

and can timely detect and deal with potential faults to ensure the safe and stable operation of the transmission line.
