110kV数字化变电站母线测控保护设计

第I页AbstractIn this paper,combined with 110kV digital substation engineering practice,a 110kVdigital substation has been designed for the two part of the electrical.This paper firstintroduces the development process and current situation of digital substation and the futuredevelopment trend,the main technical characteristics of digital substation is different from thetraditional substation,discusses the advantages and characteristics of physical structure andlogical structure of digital substation and digital substation.Secondly,the learning mode torealize a device intelligent terminal based on digital substation,the electronic transformer,merging unit and intelligent terminal of the working principle,structure and technicalperformance,and puts forward the principle and method of configuration configuration of thisstation.Then,it explains the hardware equipment,configuration principle and method,andnetworking principle and networking mode of the computer monitoring system.Again,thehierarchy framework for digital substation network equipment two times,according to thehierarchical order,discusses the station control layer,spacer layer,process layer structure,characteristics,and its function is given,and in accordance with the characteristics andrequirements of each layer of the network configuration and forget the two principle of deviceconfiguration.Finally,introduced a 110kV digital substation project details,given the specificimplementation scheme of digital substation,and the overall design scheme,design scheme,distribution device network scheme,monitoring and protection system scheme is a detaileddescription and analysis.Keywords 110kV,digital substation,intelligent primary equipment,network twotimes equipment,overall design scheme
