摘　　要：提出了一种利用故障后线路两端同步采样的电压电流量进行故障测距的算法。该算法基于精细积分法,利用故障线路两端的同步测量数据,分别计算出输电线路的沿线电压,比较两组电压,可求出故障点的位置。该方法具有计算速度快、计算结果准确等优点。仿真结果证明了该算法是可行的。In this paper, a novel fault location algorithm is presented, which uses synchronized samples of two ends of the transmission line to obtain the voltages along the line based on precise integration method. The location of the fault point is yielded by voltage comparison. An example shows that This algorithm is simple, accurate and stable.
