500 kV输电线路在线状态监测系统应用研究

摘要

输电线路状态检修工作近年来的快速发展，对线路运维数据的实时性、准确性要求越来越高。根据大同地区500 kV输电线路实际，提出了采用EPON和无线局域网技术相结合的方式构建输电线路状态在线监测系统方案。经过3年来对输电线路进行的不间断数据采集，为状态检修工作决策提供了有力依据。%The rapid development of transmission line’s status maintenance in recent years puts forward higher and higher requirements for the real-time performance and veracity of line’s operation and maintenance data. According to the reality of 500 kV transmission line in Datong Area, this paper puts forward a scheme for constructing transmission line’s online status monitoring system by adopting a mode of combining EPON (Ethernet Passive Optical Network) and WLAN (Wireless Local Area Network) technology.The uninterrupted transmission line’s data collection in the recent three years provides a strong basis for the state overhaul decision.
