110kV数字化变电站10kV线路测控保护

that is,intelligent primary equipment,analog signal fiber and network developmentof two devices.Substation two times system includes relay protection,automatic monitoringand other functions,these functions constitute the entire substation of the nervoussystem,in the entire substation occupies a very important position.Therefore,thewhole substation,as well as the whole power system,can run safely and reliably,agreat part depends on whether the two circuit can run safely and stably.In digitalsubstation,the situation is different,the two equipment standardization and themodular network is designed based on the microcomputer processing,and toreplace the traditional copper cable,greatly reduces the use of components,improvereliability.Therefore,how to realize the substation digitization and the two systemnetwork is an important topic that we need to solve now.In this paper,based on the research of digital substation,expounds the mainstructure and function of digital substation,describes the development of digitalsubstation,in the design of a substation part of the design basis,mainly for the twopart of the design of network.In the design of the two part,this paper summarizesthe function and principles,and the screening and selection of appropriate accordingto the actual situation;the design of the overall design scheme of the stationselection screen;choose the protection configuration of the station,the station andthe formation of protection configuration diagram;choose the 10kV line protectiondevice on the two,and drawing functions of the reader,the connection of theterminal diagram.This graduation design is to integrate our university four years of study,but alsofor the first time considering the combination of theory and practice,this paperdesign for substation,so I understand the need to consider many practicalengineering problems of practical.
