配电网单相接地故障定位技术的研究与应用

Research and Application of Single-Phase Grounding Fault Location Technology in Distribution Network

随着经济发展,人们的生活水平日益提高,电力需求也随之持续增加,致使配电网复杂化程度越来越高。但是,传统中压配电线路维保过程中对线路的保护措施仍然存在诸多不足,一旦发生故障,尤其在雷雨等恶劣天气条件下,会因为处理手段落后,导致发生单相接地故障,从而对输电、供电以及用户体验等产生严重影响。因此,研究配电网单相接地故障定位技术及其应用对于故障定位和修复具有重要意义,也是电力系统平稳运行的重要保障。

With the improvement of people's living standards and the increasing demand for daily life,the demand for electricity is also increasing,the distribution network is becoming more and more complex.However,there are still many deficiencies in the protection measures of the traditional medium-voltage distribution line in the maintenance process.Once the fault occurs,the treatment means are backward.Especially in severe weather conditions such as thunderstorms,single-phase ground fault will have a serious impact on power transmission,power supply and user experience.Therefore,the research and application of single-phase grounding fault location technology in distribution network is of great significance for fault location and repair,and is also an important guarantee for the smooth operation of power system.
