Research on GIS Data Model Based on New Generation Power Grid Dispatching

Power grid GIS (Geographic Information Science) data model, as the basic link in the power grid GIS visual display system, plays an important role in data organization, data management and query, and is the fundamental to ensure the stable operation of the power grid GIS visual system. In the context of the construction of the new generation of power grid dispatching system, the traditional power grid GIS data model can not meet the requirements of the new power system because of its low efficiency and difficult expansion. In order to better adapt to the construction of the new generation of power grid dispatching system, it is necessary to design a new GIS data model. By analyzing the characteristics and storage structure of GIS data in the new generation power grid dispatching system, this paper designs an object-oriented power grid GIS data model, which has been proved to be able to meet the display requirements of the new generation power grid data and realize the construction of complex line power grid model.
