Design And Realization Of Mobile Visual Monitoring And Control System For Intelligent Substation Simulation Technology

With the State Grid Corporation of China "strong smart grid" development plan putting forward,the smart grid has become the research focus of power grid development.As an important supporting part of smart grid,intelligent substation undertakes the important task of power conversion and control.The development and application of its monitoring and control system is of great significance to safe and reliable operation of substation.To this end,this dissertation used visual technology as the support to study the application of the monitoring and control system in the digital intelligent substation.In this dissertation,the research status of substation monitoring and control system was reviewed.Combined with the operation characteristics of intelligent substation,the overall framework of digital intelligent substation simulation system was proposed,and the monitoring system of intelligent substation was studied in depth.According to the requirements of information sharing and reliable operation of intelligent substation,a set of B/S and C/S hybrid architecture mode of mobile visual monitoring and control system was designed.And the functions of the mobile monitoring and control system,including monitoring,operation and control,information analysis and alarm,operation and management,was developed.The object-oriented UML modeling technology was used to model and analyze the system roles,and the data service of the secondary device was realized by MMS standard reporting service and control service.Using configuration files to preserve the "five prevention" logic rules,the lock of mistake operation was realized.Visual technology was used to achieve the construction and interaction of 3D substation scene.Therefore,remote management and local monitoring of the intelligent substation was realized,and the flexibility of substation monitoring was enhanced.Based on the needs of intelligent substation simulation application,the mobile visual monitoring and control system was developed on the Android platform by using Eclipse development tools,3dsMax modeling software,Unity engine and MySQL database.The system realizes the system operation monitoring,alarming and processing,"five prevention",operation ticket management,visual monitoring and remote management functions.The result of the research has positive significance to the construction of virtual simulation platform of intelligent substation.
