摘　　要：光纤保护因其良好性能在上海电网得到了大规模应用。文章概述了光纤保护在上海电网的应用现状,简要分析了上海电网部分主流220kV光纤纵差保护的技术特点,就光纤保护在上海电网应用中的典型问题进行了讨论,包括电流矢量同步,电容电流补偿,高阻接地故障,TA饱和和TA断线,以及光纤通道的安全性,并对上海电网光纤保护的运行管理进行了简要介绍。Fiber protections are extensively applied to Shanghai Electrical Griddue to their excellent performance. In addition to making a summary of fiber protections application to Shanghai Electrical Grid , not only technique profile of some 220kV fiber line current differential protections applied to Shanghai Grid , but also typical problem including current sampiing synchronization ,current compensation, high reactance ground fault and TA saturation and so on arising from applying fiber protections to Shanghai Electrical Grid are analyzed. Operation management principles concerning fiber protections of Shanghai Electrical Grid is briefly introduced.
