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 three-dimensional digital model library in novel power system based on power grid information model data. Firstly

the data parsing and modeling of the power grid information model are 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 is proposed and designed

and storage schemes are designed for different scenarios; the data model assembly steps are proposed based on the design of the power grid information model. Finally

files are 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 show 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.
