Multi-attribute Research and Application of BIM Based Distribution Network Engineering Equipment Model

With the promotion of the construction of intelligent distribution network and the growth of power demand, the construction scale of distribution network projects has been expanded, and the quality management of the projects has become more severe and complex. The traditional two-dimensional modeling is difficult to meet the requirements of new distribution network construction. BIM technology is based on the relevant information data of construction engineering projects for modeling. The application of BIM technology to the construction of distribution network engineering can improve the accuracy and completeness of distribution network engineering modeling, and provide reliable guarantee for the implementation of construction projects and project management. In this paper, geometric attributes, engineering attributes and ontological attributes of distribution network engineering construction elements are used, and combined with the model classification and coding of the grid three-dimensional model in the enterprise standard of State Grid Corporation, the overall platform architecture of the application layer is built, and the model of distribution network engineering construction elements is further refined based on the difference information. In addition to improving the delivery quality of distribution network engineering models, the integrated architecture from design to construction and operation and maintenance stage in the planning and construction of distribution network engineering can be effectively covered.
