摘　　要：本文针对高压输电线路两端故障录波器所录数据不同步问题，提出了一种新的利用线路两端电气量的精确故障测距算法。由于算法的理论基础是对称分量法，因此在求解故障距离时，不需要进行故障选相。利用ＥＭＴＰ进行的数字仿真证明测距结果是令人满意的。A new method of fault location based on twoterminal unsynchronized data is proposed in this paper. Theresult of fault location with this method is not affected bythe type of fault, because it is based on the theory of symmetrical component. Simulation tests with the data obtainedfrom EMTP show that with this method the fault locationcould be very accurate.
