摘要
Abstract
The open-circuit fault of substation storage battery critically challenges the steady operation of power grid.Traditional freewheeling device,however,is installed individually on each battery,resulting in cost,control,reliability problems.Thus,simple and reliable open-circuit fault localization and centralized freewheeling methods are proposed in this paper.First,by comparing the currents of battery and DC load,charge and discharge states can be determined.Then,in the state of non-artificial discharge,faulty battery can be detected and localized with the voltage and internal resistance.Finally,the centralized freewheeling device drive a diode to the faulty battery,achieving accurate and reliable freewheeling.Simulation and experimental results demonstrate the validity of the proposed methods.关键词
