摘要
以一条110kV电压等级线路为例,简要介绍了黄山地区电网光纤保护通道运行维护现状,分析了当前保护通道异常情况下检修流程的不足,并针对这一缺陷,研制出一套基于继电保护专用纤芯的通道在线监测系统。系统结合了计算机、光纤通信和光电技术,选取保护专用纤芯为研究对象,实施远端的在线监测,具备遇不良情况下的自动告警功能。系统通过功能性测试,达到提高工作效率、简化检修流程、厘清专业分工的预期目标,可以在其它电压等级线路保护中推广。
Takeing a 110 kV voltage grade line as an example, the optical fiber protection channel operation and maintenance status of Huangshan area power grid is briefly introduced. The current maintenance procedure deficiency is analysed when channel is abnormal. A set of channel on-line monitoring system is developed which is based on two dedicated fiber cores for protection relay in order to solve the defect. The system combines computer, optical fiber communication and optoelectronic technology. The specially fiber cores are selected to use for protection as research subject, implementing remote on-line monitoring with automatic alarm function in adverse circumstances. The system is proved to improve work efficiency, simplify maintenance process,clearly divide the work, achieve the desired targets through functional tests. It can be popularized in other voltage grade lines protection.
