摘要
大跨越输电线路在电力系统中处于重要地位。一旦发生故障修复非常困难,还将严重影响航道运输。对其实施在线监测是保证线路安全可靠运行的重要措施。本文以500kV狮洋至五邑大跨越输电线路在线监测系统为例,介绍了系统构成和系统要求。在此基础上,从温度监测、微气象监测、微风振动监测和视频图像监测四个方面阐述了在线监测系统的技术指标和功能实现情况。
500kV large crossing EHV AC transmission is very important in power system. Once fault occurs, the power system will be very difficult to repair. It will seriously affect the waterway transport. Thus, the real-time on-line monitoring is a necessary measure to ensure EHV AC transmission lines secure and reliable operation. Taking the EHV AC transmission line from SiYang to WuYi for example, this paper introduces the on-line monitoring system form and system requirement. Furthermore, this paper describes the technical index and function of the on-line monitoring system from four aspects which including the monitoring of conductor temperature, local meteorology a, aeolian vibration and video image.
