Modeling and Application of Transmission Line Panoramic Monitoring Platform

The power grid has gradually developed into a complex system, and the transmission lines are all over different geographical and climatic regions. The continuous change of climate has led to great challenges to the security of the power grid. The safe operation of transmission line is the basis for ensuring the safe and economic operation of power grid, and it is also the main asset of power enterprises. It is of great significance to build a transmission line panoramic monitoring platform that can comprehensively monitor, fault diagnosis and condition evaluation of transmission line. The transmission line panoramic monitoring platform is an important part of pms3.0, It is the implementation practice of digital transformation of transmission specialty in the construction of pms3.0 system, which scientifically improves the availability of transmission lines and the stability and safety of power grid operation. Considering the advantages of the application of Internet of things technology in transmission line on-line monitoring, this paper establishes a standardized panoramic information model based on the physical space, information space and application space of transmission line, and provides a general data interface to meet the data sharing between different systems and eliminate the problem of multi-source heterogeneity of information in multiple information systems in power system, It has important theoretical and practical significance for the realization of panoramic information integration platform for condition monitoring of power transmission and transformation equipment.
