摘　　要：针对220 kV线路单相瞬时接地故障,利用专业跨平台录波分析软件对线路两侧保护动作及故障录波数据的分析,故障发生时,两侧差动保护正确动作而纵联零序保护未动作的原因,并对此次保护动作做出了的评价。In connection with one instantaneous single-phase earth fault of a 220 kV power line, used specialized software to analyze protection action and fault recorder data both sides of the line, it explained the reason why the differential protection of both sides acted correctly but the longitudinal zero-sequence protection didn＇t when this failure occurred, and evaluated this protective action.

关 键 词：跨平台分析 故障录波 单相接地故障 纵联零序保护
