Design of panoramic quadratic loop model based on logical-physical mapping

In order to solve the problem of incomplete monitoring information and relative data fragmentation in the substation, a panoramic monitoring information model design method based on logical and physical mapping was proposed, and digital information covering all physical equipment, physical connections, and logical information in the station was constructed, so as to provide data support for high-end applications of operation and maintenance in the station. Through the instantiation design of physical equipment, logical loops and physical loops, a panoramic information database of substation with complete information and attributes is formed. Then, through the modeling of physical equipment, information logic, screen cabinet connection and optical cable allocation, the automatic marking of physical ports and the reverse analysis of the model are used to realize the logical and physical mapping association, form a panoramic monitoring information model in the station, and provide panoramic information data. The engineering practice shows that the panoramic monitoring information model solves the problem of insufficient panoramic digital information of substation from the design source, and effectively improves the design quality and reliability of the monitoring system.
