Design and Application of Prefabricated Substation Based on BIM Technology

As the core of advanced digital management application technology, BIM is widely used in various infrastructure construction. Prefabricated assembly substation uses advanced, reliable and environmentally friendly intelligent modular units to form an intensive closed substation. It takes digitization, networking and standardization of information as its basic requirements. Compared with conventional substation, it occupies less space, has shorter construction period, lower cost, no noise and no detection. Radiation-free and maintenance-free environment-friendly intelligent substation. A real digital information model of the whole substation depth is established by combining the Internet, big data, IoT and the construction process. Decomposition is performed in accordance with construction management and control steps to achieve model construction growth, according to Gantt chart schedule. The corresponding mechanism between the 2D code scan and the model is established, and the relationship between the digital model and the real nodes in the construction process is implemented. The life cycle of power transmission and transformation projects is facilitated by establishing appropriate management and control platform and developing the functional modules of the app. The Building Information Modeling technology is used to accurately calculate project quantities, strengthen the management and control of material cost information, provide efficient engineering quantities calculation and reduce cost. Based on the prefabricated assembly substation of 110 kV Longhua Center, this paper gives the corresponding case introduction and promotion suggestions from the aspects of prefabricated component production, assembly construction, information management technology and so on, aiming at applying it to the construction management stage of the substation industrialization project.
