摘要

提出了一种配电系统中地下电力电缆的准确故障定位方法。采用PSCAD EMTP仿真工具对电缆进行建模。在电缆建模中考虑了电缆的芯、护套和各种接地方式。该算法使用在放置故障定位器的终端记录的电压和电流测量值。仿真研究表明，即使在各种接地方式和故障条件下，该算法也能给出非常精确的输出。

A new fault location method for underground cables in distribution systems

This paper proposes an accurate fault location method for underground power cable in power distribution systems. The cable is modelled using PSCAD EMTP simulation tool. The cable core as well as sheath and various grounding modes were considered in the cable modelling. The algorithm uses voltage and current measurements recorded at the terminal where the fault locator is placed. The simulation studies have proved that the proposed algorithm gives very accurate outputs even under various grounding modes and fault conditions.
