摘要
配网故障频发,给运维带来严峻挑战,提出一种基于光纤通信技术的配网运检故障定位新方法。该方法综合利用光时域反射、布里渊散射、波分复用技术,实现对配网光缆的全程实时监测和精确故障定位。通过仿真实验,证明该方法能准确识别断纤、接头、弯曲等典型故障,定位误差小于15 m,温度测量误差小于0.5℃,为配网智能运检提供可靠技术支撑。
Frequent failures in the distribution network create significant challenges for operation and maintenance.This paper proposes a new method for fault location in distribution network inspection using fiber optic communication technology.The method uses optical time-domain reflectometry,Brillouin scattering,and wavelength division multiplexing technology to monitor the entire distribution network optical cable in real-time and locate faults precisely.Simulation experiments show that this method can accurately identify typical faults such as fiber breaks,joints,and bends.The location error is less than 15 m,and the temperature measurement error is less than 0.5℃.This method provides reliable technical support for intelligent operation and inspection of the distribution network.
