摘　　要：研究并改进一种铁路10 kV电力贯通线故障方向快速识别算法。该算法仅利用故障后电流的相位信息即可确定故障方向,进而实现故障区域定位,且可与通信通道配合构成一种新型差动保护方案。该算法具有算法流程简洁、识别精确、快速等优点。Studies are made for improving of a fast recognition algorithm for direction of earthing fault of 10 kV electric power through line of railway,by application of this algorithm,it is able to determine the direction of fault by only application of information of phase position of the current after the fault is occurred,thus realizes the fault location and establioshes of a new type of differential protection scheme with coordination of communication channels.The algorithm has advantages of concise calculation flow,accurate recognition and fastness.
