Design of Electric Power Enterprise Data Integration Platform Architecture Based on CIM

Abstract

The heterogeneity of information systems constructed in different historical periods by electric power enterprise produces the problem of Information Island, which affects the effective use of information resources. This paper starts with analyzing the adoption status of information systems within power utilities, summarizes the data source types and their relationships. Meanwhile, the data integration necessity in power utility is discussed, and the main problems that include the heterogeneous and distribution of data sources, no unified identifier for power system data entities, lacking of entity associations are analyzed minutely. In order to solve these problems, the data integration platform architecture is designed, which uses CIM as the common data model in electric power enterprise. Through data integration platform, the heterogeneous data sources are mapped to general CIM model, and then the data services are provided by the platform through the well-defined data service interfaces. The data users can request data service via data service interface, and retrieve the object set that accord with specific CIM profile. Moreover, the meta-database schema of data integration platform is introduced in detail. Through the meta-database, the problems that include establishing associations for entities of various data sources, and the unified identifiers for same entities are solved.
