电网工程中配电线路故障定位技术的应用研究

Research on the Application of Distribution Line Fault Location Technology in Power Grid Engineering

配网线路运行时接地故障几率大,会致电气设备损毁等问题,单相接地故障还会产生谐振过压危害人员安全。为降停电损失,该文详细分析了配电故障,提出行波法等多种故障定位技术,为故障排查处理提供参考,以保障电网工程运行效益。

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.
