摘　　要：利用EMTP和MATLAB程序详细仿真了一种不要求两端数据同步的双端测距算法。同时利用陕西电网一次C相接地故障的实际数据对测距算法的实用性进行了验证,结果表明,该测距算法仿真效果好,具有一定实用价值。Using unsynchronized data, a two-terminal based fault location algorithm is proposed in this paper. The simulated results by EMTP and MATLAB are analyzed and compared here. The thesis uses the given data by digital fault recorder with a C phase-grounded fault taken place at Shanxi electric network in 2003 to verify it. The results show that above-mentioned algorithms have good practicability.
