非侵入式低压配电网短路事故检测及定位方法
Non-Intrusive Fault Detecting and Locating Method in Low-Voltage Distribution Network
摘要
Abstract
Non-intrusive load monitoring (NILM) is an advanced measuring technology which does not require intrusive construction into users and complicated communication channel.In this paper,the NILM technology is innovatively applied into short-circuit-fault detection and location.Firstly,based on the results of experimental and theoretical analysis,the criterion and the relevant setting process for short-circuit fault with the breaker protection is proposed.Secondly,the fault location algorithms under NILM architecture are presented,which contains three steps:primary locating method for distribution level,primary locating method for important branch based on power drop model,and accurate location method by reusing sub-metering data.Totally four single-phase short-circuit accidents are detected and located during the experiments,which effectively improves the safety level of power users and reduces the construction cost of monitoring system.关键词
