Research Of Distribution Common Information Model Based On State-Grid CIM

To facilitate data exchange between systems, the State Grid common information model (SG-CIM) is designed by the State Grid Corporation of China based on the international standard IEC61970, IEC61968 Common Information Model (CIM). SG-CIM model is expanded and re-organized IEC61970/61968 CIM model.Standards for the State Grid Corporation of the common data model (SG-CIM) conducted a general definition and description, designed to protect the standardization and regulation of information technology in the information system model and related applications. But practice shows that the existing distribution network link model and standard is still not fully meet the objective needs of integration-oriented.In response to these problems, the paper conducted a detailed study. The paper gave a simple introduction on the current status of the study CIM model and mastered the current research directions of CIM model. The CIM modeling language-Unified Modeling Language (UML) was introduced. The paper gave detailed analysis of IEC61970/61968 two criteria, and pointed out that the series of standards research focuses on common information model and interaction norms. Combined with the actual situation of distribution network the SG-CIM model is extended, including the distribution network topology model and new energy (wind power, solar power, fuel cell power generation). Finally, the extension of SG-CIM model is applied to the engineering practice, and details the SG-CIM application in practice, including the transfer of the business with a platform to build data integration, data integration module design and so on.
