In electric power transmission and distribution, the Common Information Model (CIM), a standard developed by the electric power industry that has been officially adopted by the International Electrotechnical Commission (IEC), aims to allow application software to exchange information about an electrical network.〔(IEEE.org | The impact of PAP 8 on the Common Information Model (CIM) )〕 The CIM is currently maintained as a UML model.〔(Electric Light and Power.com | Using the common information model for enterprise integration )〕 It defines a common vocabulary and basic ontology for aspects of the electric power industry. The CIM models the network itself using the 'wires model'. This describes the basic components used to transport electricity. Measurements of power are modeled by another class. These measurements support the management of powerflow at the transmission level, and by extension, the modeling of power through a revenue meter on the distribution network. The CIM is also used to derive messages for the wholesale energy market. The CIM can be used to derive 'design artifacts' (e.g. XML Schema, RDF Schema) as needed for the integration of related application software. The standard that defines the core packages of the CIM is IEC 61970-301, with a focus on the needs of electricity transmission, where related applications include energy management system, SCADA, planning and optimization. The IEC 61970-501 and 61970-452 standards define an XML format for network model exchanges using RDF. The IEC 61968 series of standards extend the CIM to meet the needs of electrical distribution, where related applications include distribution management system, outage management system, planning, metering, work management, geographic information system, asset management, customer information systems and enterprise resource planning. == Difference between CIM & SCL == CIM and Substation Configuration Language (SCL) are developed in parallel under different working groups of IEC TC 57. Though both have the ability to exchange model and configuration information between different equipment or tools and use XML for storage, there are lot of differences between both the standards. #CIM is completely developed based on UML which is developed on the basis of inheritance. SCL representation is sequential or hierarchical in nature. #Although the CIM is not limited to modeling equipment, the CIM approach gives emphasis on the equipment inheritance and its interconnection whereas SCL starts from a functional point of view. #CIM is broadly applied to enterprise integration and related information exchanges between systems including, but not limited to, EMS, DMS, Planning, Energy Markets and Metering, where SCL is limited to exchange of data within substation equipment and tools. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Common Information Model (electricity)」の詳細全文を読む スポンサード リンク
