摘要
光纤复合架空地线(OPGW)是一种应用广泛的电力线缆,兼具架空高压输电地线和光纤通信载体的功能。OPGW长期工作在户外,其安全会受到环境因素和人为因素的影响,监测和维护其运行状态是电力系统正常运行的重要保障。文章介绍了基于布里渊散射的分布式光纤传感技术在电力系统OPGW状态监测方面的应用现状,讨论了目前存在的问题,并对未来的应用进行了展望。
Optical Fiber Composite Overhead Ground Wire（OPGW）is a kind of widely used power cables,which has the function of overhead transmission line and optical fiber communication carrier.OPGW works outdoors for a long time,which will be affected by environmental factors and human factors.Monitoring and maintenance of OPGW is an important guarantee for the normal operation of the power system.In this paper,we first introduce the current development of the distributed optical fiber sensing technology based on Brillouin scattering in OPGW monitoring.Then the existing problems and future application prospect are also discussed.
