Research on the construction method of panoramic information model between multi heterogeneous systems

Due to different business responsibilities, the existing power dispatching system is built independently, and there is a lack of unified information exchange model between different systems. Based on the requirements of panoramic information resource access for heterogeneous systems, this paper proposes the key technologies of building panoramic information model for heterogeneous systems: for the existing business models with internal connections, the conventional model combination method is used to combine them to generate the basic information model; based on the segmented normalized minimum edit distance algorithm, the name similarity of data object model in heterogeneous system is matched to realize the preliminary matching of heterogeneous system model; combined with the information model set of independent identification, the mapping relationship of model names, the full topology connection relationship and the list of distributed information of discrete information among heterogeneous systems are automatically formed, and the grid regulation panoramic model information for heterogeneous systems is formed. It provides data base and technical support for panoramic access of information resources in the environment of wide area heterogeneous system to satisfy the requirements of new energy scheduling and control.
