In order to clarify the selection criteria for the data organization structure of the power grid analysis model,a study was conducted on the applicability of its chart organization method.Based on the ontology concept,the component list,component diagram,and hierarchical diagram data model for power grid analysis model were constructed,and the performance was tested and compared under power grids with different scales.The test results provide a quantitative relationship between the retrieval performance of the three,indicating that the retrieval performance of the constructed hierarchical graph is about 10 times and 40 times that of the component diagram and component list in multi-layer topology retrieval,respectively.It can provide a basis for selecting the data organization structure of the power grid digital base.
