摘　　要：介绍了一种双端同步采样的输电线路故障定位方法。此方法以ＧＰＳ作为同步时间基准，只需线路两端的电流电压采样值，克服了过渡电阻的影响，不受故障类型、故障点位置、故障发生时刻和电力系统运行条件的影响，并将其推广到双回线。仿真实验表明，本算法有较高的精度和简易性。In this paper an algorithm for fault location of transmission line is introduced. Based on synchronous clock provided by GPS, this approach requires only synchronized samples of currents and voltages at two ends of a line, it can exclude the influence of fault resistance, fault type, fault location and system operation condition. EMTP simulation test shows that this algorithm has high accuracy and robustness.
