61970-301©1EC:2003 -10- INTRODUCTION This standard is one of the IEC 61970 series which define an application program interface (API) for an energy management system(EMS).This standard is based upon the work of the EPRI Control Center API(CCAPI)research project(RP-3654-1).The principle objectives of the EPRI CCAPI project are to: Reduce the cost and time needed to add new applications to an EMS. Protect the investment of existing applications or systems that are working effectively with an EMS. The principal task of the CCAPI Project is to produce requirements and draft text for standards to facilitate the integration of EMS applications developed independently by different vendors, between entire EMS systems developed independently,or between an EMS system and other systems concerned with different aspects of power system operations,such as generation or distribution management systems (DMS).This is accomplished by defining application program interfaces to enable these applications or systems access to public data and exchange information independent of how such information is represented internally.The Common Information Model (CIM)specifies the semantics for this API.The Component Interface Specifications(CIS)specify the content of the messages exchanged. This part of the standard,IEC 61970-301,defines the CIM Base set of packages which provide a logical view of the physical aspects of Energy Management System information.Part IEC 61970- 302 defines the financial and energy scheduling logical view.Part IEC 61970-303 defines the SCADA logical view.The CIM is an abstract model that represents all the major objects in an electric utility enterprise typically needed to model the operational aspects of a utility.This model includes public classes and attributes for these objects,as well as the relationships between them. The objects 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
