Unified Model of Substation Equipment State Information Based on CIM

Standard IEC61968 and IEC61970 enacted by International Electrotechnical Commission (IEC) built a basic model for the equipment objects in electric power system. According to the actual needs in state evaluation of substation equipment, unified model of substation equipment state information was established. The model follows standard Common Information Model (CIM). By researching the related information and components of substation equipment, the model was classified as Core3 Package, Domain3 Package, History Package, Substation Equipment Package, and Test Package. The five packages generalize the description of the substation equipment, equipment testing, historical data and other aspects. This model built an integrated information platform for the state evaluate of substation equipment and offered exhaustive substation equipment state information for apparatus attendant and relevant units. With the model substation equipment state information became more unified.
