摘要
同杆并架双回线路光纤纵差保护对两个通道的采样同步及通道安全要求更高。利用数据通道同步模型对四川省某变电站同杆并架双回线路光纤差动保护通道告警异常进行分析,发现并解决了RCS-931EG装置的软件缺陷,这可为排查同类的光纤通道告警异常提供重要参考。
It demands higher requirements for synchronized sampling and channel security within the two channels during fiber longitudinal differential protection for double circuit lines on the same tower.By applying digital channel synchronized model,the abnormal alarm which is from longitudinal differential protection for double circuit lines on the same tower of certain substation in Sichuan province,is analyzed,and flaws are found and killed from the software of device RCS-931EG.This provides important reference to the fiber channel abnormal alarming.
