中文摘要:

在电力系统中高压输电线路出现故障的频率较高，在短时间内确定故障发生位置对电力公司来说显得尤为重要。精确的故障定位确保了电力系统运行的稳定性，也有助于分析特定的电网。本文通过一种有效的单端故障测距算法，利用故障电流、故障电压以及线路参数来确定故障点的位置。并通过Matlab进行建模仿真，测距结果受线路电抗大小影响。

英文摘要:

In the power system, the frequency of transmission line failure is high, in a short time to determine the location of the failure of the power company is particularly important. Accurate fault location ensures the stability of the power system operation and also helps to analyze the specific grid. In this paper, an effective single line to ground fault location algorithm is used to determine the position of the fault point using fault current, fault voltage and line parameters. And the simulation is carried out by Matlab, that results are affected by the line reactance.
