Research On Key Technology Of Intelligent Substation And Design Of 110kV Intelligent Substation

Nowadays,the computer technology is highly mature,the network communication technology has made great progress,and the power grid automation system is becoming more and more perfect.With the emergence of intelligent devices such as intelligent switch,real-time measurement and control of substation operation parameters is gradually realized,and the information exchange of power grid equipment is more accurate and convenient.The primary and secondary equipment of substation is becoming more and more digital and intelligent,and the substation has entered the intelligent era.This paper discuss the basic meaning and functional characteristics of intelligent substation,and study the core technical characteristics of intelligent substation.Taking a 110 k V intelligent substation in Jingdezhen,Jiangxi Province as an example,the design of 110 k V intelligent substation is carried out from the aspects of substation construction necessity,power grid load analysis,primary design of power system,secondary design of power system and selection of main equipment.
