Research And Application Of Fault Handling Technology Based On Distribution Network Automation

In order to improve the reliability of distribution network,it is necessary to focus on the construction of distribution network automation.The goal of building distribution automation is to effectively improve the power supply transfer level,self-healing ability and reliability of the State Grid.In addition,it can also promote the stable development of China’s power system.The solution of the problems of distribution network failures and intelligent management of distribution networks are essential issues of the current power grid.The emergence of distribution automation network has laid an important foundation for improving the operation and self-healing of the distribution network.The fault location,isolation and recovery are key technologies for fault treatment of distribution automation network,which also have extreme importance for reducing power outage area and improving the reliability of power supply of the distribution network.In this paper,based on distribution automation network,the research about fault treatment techniques like switch movement,logic analysis and healing strategy is investigated.The main work is done as follows:Firstly,the basic concepts of distribution automation system are illustrated.The overall framework and functional allocation schemes for distribution automation systems are defined.Secondly,the different treatment modes of feeder automation,as well as the matching and realization modes of feeder automation are analyzed.Through the study of the methods of fault treatment of power supply lines,the feeder automation mode work schemes under different regional conditions are determined.Thirdly,the actual situation of the distribution automation in Jinzhou is studied and the running situation and the adopted mode of the feeder automation are analyzed.Finally,the actual application effects of the distribution network automation operation strategy in Jinzhou are analyzed.Through the comparison of the technical indicators,load loss and other related data by quantitative calculation,the actual effect of the distribution network automation fault treatment are reflected.Besides,to promote the development of distribution network projects,according to the above research,some suggestions for the automation operation of distribution networks in the future are proposed.The research in this article can provide a theoretical basis for the design of power automation construction and transformation schemes.
