提出了利用线路一端数据进行故障测距和距离保护的两种数值算法。这两种算法都只需要电流信号作为输入数据。电压信号对于确定到故障的未知距离是不必要的。提出了一种最频繁相接地故障的解决方法。算法相对简单，易于在线实现。该算法允许准确计算故障位置，而不考虑故障电阻和负载。为了说明新算法的特点，稳态和动态测试。
Two numerical algorithms for fault location and distance protection which use data from one end of a transmission line are presented. Both algorithms require only current signals as input data. Voltage signals are unnecessary for determining the unknown distance to the fault. The solution for the most frequent phase to ground fault is presented. The algorithms are relatively simple and easy to be implemented in the on-line application. The algorithms allow for accurate calculation of the fault location irrespective of the fault resistance and load. To illustrate the features of the new algorithms, steady-state and dynamic tests are presented.
