Design And Application Of Integrated Automation Monitoring System For 110kV Jin Wan Substation Of ZhanJiang

The substation integrated automation monitoring system is composed of various hardware and software facilities,which integrates computer technology,communication technology,electronic technology,measurement technology,control technology,information processing technology and so on.The substation integrated automation monitoring system integrates the traditional substation control system,automatic device,signal system,remote control system,fault recording and on-line monitoring and fault self diagnosis system.After reorganized,and optimized,it is designed into a complete set of intelligent,automated integrated system.This system monitors,measures,protects,controls and regulates the operation of substation electrification equipment and power systems.Substation integrated automation system to improve operational reliability and safety,save on the operation and maintenance costs,and effectively improve the quality of power supply.The main functions of the substation integrated automation monitoring system include:data acquisition and recording,data processing,monitoring and control function,communication function,fault recording and locating,event recording,real-time monitoring function,interactive function,print function etc.The substation integrated automation monitoring system include centralized panel and layered and distributed structure type,now widely used in substation is a distributed structure type.This paper analyzes and studies the design of 110 kV Jinwan substation integrated automatic monitoring system,discusses the advantages of adopting hierarchical distributed network structure in substation,and summarizes how to arrange the equipment of substation integrated automatic monitoring system.Based on the analysis and research of communication and function of 110 kV Jinwan substation integrated automatic monitoring system,the basic requirements of communication and function of substation integrated automatic monitoring system are discussed.In this article,we also discussed methods to solve the key time-consuming aspects in thetroubleshooting tasks of circuit breakers and knife sluice operation,and designed contact monitoring functions.According to the characteristics of multiple typhoons in ZhanJiang,physical communication channels are easily interrupted by typhoons.Problems,explore the trial of wireless emergency communication channels.
