Research on technical architecture and application of power grid digital delivery based on BIM+GIS

Building Information Model (BIM) technology supports the fine design and management of power grid with its 3D modeling, information integration and cooperative operation capabilities. Geographic Information System (GIS) technology shows its potential in power grid planning, resource allocation and emergency response with its spatial analysis, geographic positioning and data visualization functions. The technical framework proposed in this study takes data as the core, platform as the support and application as the guidance, and realizes the digital and intelligent management of the whole life cycle of power grid. The features of this architecture include data fusion, platform collaboration, comprehensive application and intelligent decision-making. Key technologies include data fusion technology of BIM and GIS, 3D modeling and visualization technology, and optimization of digital delivery process. Through the application research of a smart grid project in a city, the remarkable effect of BIM+GIS fusion technology in improving design efficiency, construction accuracy and operation and maintenance management level is verified. At the same time, this paper also analyzes the challenges encountered in technology implementation, and puts forward corresponding solutions, including formulating unified data standards, promoting platform standardization and talent training, so as to promote the development and application of BIM+GIS fusion technology in power grid digital delivery.
