Research on the construction technology of a new three-dimensional digital model library for power grid based on power grid information model data
In response to the problems of incomplete data parsing, parsing errors, and low universality of intermediate data structures in parsing methods, this paper proposes a research on the construction technology of a three-dimensional digital basic model library based on power grid information model data. Firstly, the data parsing and modeling of the power grid information model were proposed, which can be divided into basic graphical element parsing and individual model parsing. The model equipment is assembled through Boolean operations of graphical elements; Aiming at the multi-source heterogeneous data of the power grid information model, the E3M storage format of the power grid information model was proposed and designed, and storage schemes were designed for different scenarios; Proposed the data model assembly steps based on the design of the power grid information model; Finally, files were randomly selected from the State Grid digital management application system for verification of data format and content correctness, integrity checks, and other information. The experimental results showed that the designed system can achieve a file information accuracy rate of over 99.6%, which is 5.7% higher than existing detection methods, achieving standardized model data storage management.
