摘　　要：光纤通道告警是微机保护最常见的故障,对于经常发生的瞬时告警瞬时复归、反复发生的情况,由于故障现象难以捕捉,给故障处理带来很大不便。针对典型电力系统应用场景,结合无线通信通道状态信息获取方式和长短报文结合、信息分层分类处理的技术,设计了通道状态在线感知装置,结果为该装置可实时监测通道质量、定位异常区段、记录异常报文。结果表明,该技术的运用实现了通道状态信息的在线感知及离线挖掘,有效解决了变电站纵联光纤通道无记录、故障区间定位难等问题,缩短了继电保护通道故障处理时间,大大提升了工作效率。Fibre channel alarms are the most common failures of microcomputer protection.For the frequently occurring instantaneous alarms that instantly reset and recur,it is difficult to capture the failure phenomenon,which brings great inconvenience to the troubleshooting.Aiming at typical power system application scenarios,this paper designs a channel status online sensing device based on the wireless communication channel status information acquisition method,long and short message combination,and information hierarchical classification processing technology.The result is that the device can monitor channel quality in real time and locate abnormalities,section and record abnormal messages.The results show that the application of this technology realizes the online perception of channel status information and offline mining,effectively solves the problems of no record in the longitudinal fiber channel of the substation,difficulty in locating the fault section,and shortens the relay protection channel the troubleshooting time greatly improves work efficiency.
