Secondly the present fault location on hv tran *** ission work has been mented on . tree fault location methods based on the power frequency fault data of o - terminal are proposed
本文其次对现有高压输电线路 故障定位方法 进行了综合评述，在此基础上提出了三种基于双端数据的工频故障测距算法。
In this thesis , the fault location algorithms of hv tran *** ission pne are evaluated at first , then the factors that affect the accuracy of the fault location are *** yzed , and the proper solutions are presented
本文首先对现有高压输电线路 故障定位方法 进行了综合评述，在此基础上对造成稳态故障测距误差的一些尚未获得满意消除的因素进行了深入的探讨，并提出了相应的解决方法。
based on the *** ysis of the transient and stable features of fault information on pne in single carrier power supply with ineffective grounding neutral , this paper puts forward a new method for fault location in *** all current power system called " gradual identifying law "
本文针对这一问题,在深入研究了中性点非有效接地单端供电系统发生单相接地故障后线路上的各处故障信息的暂态特性和稳态特性的基础上,提出了一种新的小电流接地系统单相接地 故障定位方法 - “递进信息法” 。
