摘要

针对目前电缆故障引起的频繁停电维修影响了人们正常生活的问题

提出了一种基于偏振光时域反射仪分布式光纤传感技术的电缆安全状态监测系统

该系统通过计算差值图的峰度系数来衡量曲线变化的陡峭程度

从而进行入侵点的判断。实验表明

系统工作于1μs的脉冲宽度时对扰动位置的判断误差低于100m。通过设置合适的振铃宽度

可以将误报率降至0.5%以下。在不同的电缆长度和电缆布置环境情况下

能够通过对系统参数的配置来满足使用需求。

Abstract

In order to ensure the good condition of the cable

a lot of manpower have been used to conduct inspections

which are inefficiency for the power companies.Current power outage caused by cable failure seriously affects people’s normal life.Therefore

an effective monitoring system is required to monitor the status of the cable online.In this paper

we propose a cable safety monitoring system based on polarization optical time-domain reflectometer.The system judges the intrusion point by calculating the kurtosis coefficient for the different maps.When the system is operating at a pulse width of 1μs

the error on the intrusion localization is less than 100 m.By setting the ring width appropriately

the false alarm rate can be reduced to be less than 0.5%.In the case of different cable lengths and cable layout environments

the requirements for different users can be satisfied by setting the parameters under different system configurations.
