摘　　要：针对寺河岳东环网线路投运过程中出现的RCS9613B型光纤纵差保护差流零漂值大问题,通过现场对RCS-9613B光纤纵差保护进行检查、测量、分析,总结出差流零漂值大的原因,并提出改进措施,以确保岳东环网线路的安全稳定运行。In view of the big problem of differential current zero drift value of RCS9613 Boptical fiber longitudinal differential protection during the operation of Yuedong transmission line,through the on-site inspection,measurement and analysis of RCS-9613 Boptical fiber longitudinal differential protection,the reasons for the high zero drift value of differential current are concluded in this paper.It also puts forward the improvement measures to ensure the safe and stable operation of the Yuedong line.
