Research on Parametric Modeling and Standardized Delivery of Substation Buildings Based on Domestic BIM Platform

Against the backdrop of increasing demands for efficiency and standardization in the construction, expansion, and renovation of substations within the power industry, the digital transformation of substation civil engineering faces critical challenges such as difficulties in parametric component invocation, disconnection between 2D and 3D data, and reliance on foreign BIM platforms. To address these issues, this study first adopts parametric family library construction technology based on a domestic BIM platform to define geometric parameters and attribute association rules for key components such as walls, floors, doors, windows, and cable trenches, enabling parametric-driven design and efficient component reuse. Second, by developing data interaction interfaces through the domestic BIM platform’s API, a bidirectional linkage mechanism is established—where parameter changes in 2D drawings drive automatic updates of 3D models, and geometric adjustments in 3D models trigger real-time corrections in 2D drawings—ensuring synchronous data consistency. Finally, a standardized delivery system is implemented using vector graphics mapping algorithms, overcoming technical bottlenecks in converting 3D models to vector graphics. Test results demonstrate that the bidirectional linkage technology achieves a response delay of ≤15 seconds and data consistency ≥99.3%, while the geometric information integrity of the delivery system reaches ≥99.3%. This research fills a technical gap in digital design for substation buildings within domestic BIM platforms, providing a viable pathway for reducing dependence on foreign software and advancing technological autonomy in the power industry.
