IEC 61970-301:2009(E) defines the Common Information Model (CIM) base set of packages which provide a logical view of the physical aspects of an energy management system including SCADA (Supervisory Control and Data Acquisition). Whilst there are multiple IEC standards dealing with different parts of the CIM, there is a single, unified normalized information model comprising the CIM behind all these individual standards documents. This second edition contains the following main changes with respect to the previous edition:- change of the naming hierarchy,- replacement of several classes,- addition of several new classes,- many editorial corrections to resolve issues included in the first edition.This publication is of core relevance for Smart Grid.
Defines the Common Information Model Base set of packages which provide a logical view of the physical aspects of Energy Management System information. Is part of the IEC 61970 series, which defines an Application Program Interface (API) for an Energy Management System (EMS).
IEC 61970-301:2011 deals with the common information model (CIM), an abstract model that represents all the major objects in an electric utility enterprise typically involved in utility operations. The object classes represented in the CIM are abstract in nature and may be used in a wide variety of applications. The use of the CIM goes far beyond its application in an EMS. This standard should be understood as a tool to enable integration in any domain where a common power system model is needed to facilitate interoperability and plug compatibility between applications and systems independent of any particular implementation. Major changes from the second edition include the following: - Addition of regulation control models; - new "OperationalLimits" package for equipment ratings; - addition of partial ownership specification; - enhancement of LoadResponseCharacteristic; - change from non-SI units to SI units.
