摘要

PPROBLEM TO BE SOLVED: To make it possible to locate a ground fault point with high precision, though a fault locating method is of a current shunting ratio method or an impedance method. PSOLUTION: This transmission line fault locator is provided with a current shunting ratio/impedance computing part 81 that obtains a current shunting ratio 'k' or impedance 'k' for every instantaneous value based on actually measured data of a transmission line and averages the current shunting ratio 'k' and the like during a prescribed period of time after the occurrence of a fault, and a fault locating part 82 that locates a ground fault/short-circuit fault point based on the average current shunting ratio 'k' obtained. The fault locating part 82 obtains simulated current data in assumption that a fault occurred using a system simulator and obtains a simulated current shunting ratio 'k' and the like from the data. While making the simulated fault point change on the system simulator, the fault locating part 82 determines the simulated fault point that corresponds to the simulated current shunting ratio 'k' as an actual fault point, by comparing the simulated current shunting ratio 'k' corresponding to the simulated fault point with the average current shunting ratio 'k' and the like one by one, and by searching a simulated current shunting ratio 'K' and the like to which both ratios are nearest.

要解决的问题：尽管故障定位方法是分流比方法或阻抗方法，但仍可以高精度地定位接地故障点。

解决方案：该传输线故障定位器配备有电流分流比/阻抗计算部分81，该部分基于传输线的实际测量数据和每个瞬时值获得电流分流比“ k”或阻抗“ k”。在发生故障后的规定时间段内平均电流分流比“ k”等，并且故障定位部分82基于平均电流分流比“ k”来定位接地故障/短路故障点获得。故障定位部分82假设使用系统模拟器发生故障而获得模拟电流数据，并从该数据获得模拟电流分流比“ k”等。当在系统模拟器上改变模拟故障点时，故障定位部分82通过比较对应的模拟电流分流比“ k”，将与模拟电流分流比“ k”相对应的模拟故障点确定为实际故障点。通过平均电流分流比“ k”等逐一地找出模拟故障点，并通过搜索两个比率最接近的模拟电流分流比“ K”等。
