New method for designing the spatial database of power network

It is very important for the development of information technology in the power industry to store and analyze the power networks using the Geography Information System (GIS). The ordinary space and topology data is necessary to the power networks in GIS, the data for describing the logical structure of the networks is also necessary. In order to store and analyze the logical structure data and meet the need of uniform management of data and development of distributed information system, a set of hierarchical tables based on the relation data model was designed to match the characteristic of the power networks by improving the traditional space + attribution data management mode in GIS. It has been shown that the tables can represent the logical structure data of the macro power networks and the local electric networks and are convenient to the connectivity analysis and flexible modification of networks.
