電網(wǎng)工程中配電線路故障定位技術(shù)的應(yīng)用研究

摘要：配網(wǎng)線路運(yùn)行時(shí)接地故障幾率大，會(huì)致電氣設(shè)備損毀等問題，單相接地故障還會(huì)產(chǎn)生諧振過壓危害人員安全。為降停電損失，該文詳細(xì)分析了配電故障，提出行波法等多種故障定位技術(shù)，為故障排查處理提供參考，以保障電網(wǎng)工程運(yùn)行效益。

Abstract： Grounding faults during the operation of distribution network lines have a high probability， which can cause damage to electrical equipment. Single-phase grounding faults can also cause resonance overvoltage， which is harmful to personnel safety. In order to reduce the loss of power outages， this article analyzes in detail the distribution faults， proposes multiple fault location techniques such as the traveling wave method， and provides references for troubleshooting to ensure the operating efficiency of the power grid project.

Keywords： power grid engineering; distribution line; fault location technology
