Data Model Design of Dispatching, Operation and Maintenance of Power Information System Based on CIM

At present, Chinese power grid management has entered the stage of information management, and various production and management systems have emerged, but these systems generally have problems such as inconsistent data models and non-standard data access interfaces. Therefore, following the IEC61970 standard, this paper studies a grid public data model based on DMTF-CIM expansion. The model takes the integration of dispatching, operation and maintenance of power grid information system as the entry point and adopts the technical architecture based on the J2EE platform to design and implement. This paper focuses on the modeling method, data architecture, data logic and data Integrated design to realize data interoperability and integration of multiservice systems.
