Because of the high complexity and large scale of transmission line engineering, a large amount of data will be generated in the traditional two-dimensional (2D) design process, and the work of each stage is relatively independent. The design results are difficult to be effectively managed and integrated, and timely information interaction within and between specialties can not be achieved. BIM (Building Information Modelling) technology has powerful functions of digitalization and information management. This paper studies the application of BIM technology in three-dimensional (3D) design of overhead transmission lines. With the help of Revit platform and secondary development technology, combined with “Xinfu 110 kV transmission and transformation” project, a standardized family library of overhead transmission lines is established, and a set of algorithms for automatic sorting of insulator strings and automatic generation of overhead lines are developed, which realizes the parametric design of the lines in 3D environment. The whole process is centered on BIM information model database, which solves the problem of information management and interaction in traditional 2D design, and improves the design efficiency and quality.
BIM (Building Information Modelling) technology has the advantages of visualization and informatization. But BIM technology is mainly used in the construction field, and the application of BIM technology in transmission project is less. This paper research the application of BIM technology in the three-dimensional design of transmission lines. Based on the Revit platform and using secondary development technology, the parameterized model library of transmission line was built by Revit, such as work wells, cable trenches and towers, and the three-dimensional curve fitting algorithm was applied to design the path of the transmission line, and finally the three-dimensional digital model of the transmission line was built. The research results in this paper can provide a new method for 3D design in the field of transmission project.
