Design And Application Of Integrated Automation Monitoring System For 220kV Guanqiao Substation

The integrated automation monitoring system includes two functions of monitoring and control,which are the eyes and meridians of substations,supporting the safe and stable operation of substations.The integrated automation monitoring system is composed of two parts of the power system dispatching automation monitoring system and the substation automation monitoring system.Power system dispatching automation monitoring system monitors all plant stations in Zhanjiang area.It monitors and controls the entire power grid system,including power plants and substations.The substation automation monitoring system monitors a single site.It only faces the substation's own monitoring and control.The substation automation monitoring system has two types of centralized group screen and hierarchical distributed system.Nowadays,the substation is widely used is a hierarchical distributed structure,the main function are data acquisition,event sequence recording,fault recording and distance measurement,monitoring and control function,real-time monitoring function of contact state,man-machine contact function and print work.Energy,data processing and recording function,communication function and so on.In this paper optimizes the localization design of the integrated automation monitoring and control system of 220 kV Guanqiao Substation are optimized.Discusses the method of solving the key time consuming link in the fault handling task of the breaker and knife sluice operation,and designs the real-time monitoring function of the connection.According to the characteristics of the typhoon in Zhanjiang,the physical communication channel is easily affected by the typhoon.The design and application of wireless emergency communication channel is explored.
