61970-301©1EC:2003 -14- NOTE 1-The package definitions are loosely based on the "Conformance Blocks"that were defined for the CIM specification version 7 defined in the EPRI CCAPI project. NOTE 2-The contents of the CIM defined in this specification were obtained from a straight conversion of the CCAPI CIM static information model defined in the CCAPI CIM Version 10. NOTE 3-Informative Annex B contains a mapping of the information modeling notation used in the CCAPI CIM Version 7 to the UML used in this standard specification.This Annex is intended to assist those readers who have previously worked with the CCAPI CIM and who now need to adopt the new UML notation.Those readers not acquainted with the previous CCAPI CIM notation may choose to not read Annex B. 4.2.1 Core This package contains the core Naming,PowerSystemResource,EquipmentContainer,and ConductingEquipment entities shared by all applications plus common collections of those entities.Not all applications require all the Core entities.This package does not depend on any other package,but most of the other packages have associations and generalizations that depend on it. 4.2.2 Topology This package is an extension to the Core Package that in association with the Terminal class models Connectivity,that is the physical definition of how equipment is connected together.In addition it models Topology,that is the logical definition of how equipment is connected via closed switches.The Topology definition is independent of the other electrical characteristics. 4.2.3 Wires The Wires package is an extension to the Core and Topology package that models information on the electrical characteristics of Transmission and Distribution networks.This package is used by network applications such as State Estimation,Load Flow and Optimal Power Flow. 4.2.4 Outage This package is an extension to the Core and Wires packages that models information on the current and planned network configuration.These entities are optional within typical network applications 4.2.5 Protection This package is an extension to the Core and Wires packages that models information for protection equipment such as relays.These entities are used within training simulators and distribution network fault location applications. 4.2.6 Meas The Meas package contains entities that describe dynamic measurement data exchanged between applications 4.2.7 LoadModel This package provides models for the energy consumers and the system load as curves and associated curve data.Special circumstances that may affect the load,such as seasons and daytypes,are also included here.61970-301  IEC:2003 – 14 – NOTE 1 – The package definitions are loosely based on the “Conformance Blocks” that were defined for the CIM specification version 7 defined in the EPRI CCAPI project.
