Semantic Interoperability for Historical and Real Time Data Using CIM and OPC-UA for the Smart Grid in Mexico

摘要

This paper describes the logic architecture implemented for exchanging data gathered in Real-Time as well as stored in Historical repositories, adopting a semantic interoperability architecture based on the Common Information Model (CIM) -which is defined in standards IEC 61968, IEC 61970 and IEC 62325-, and the OPen Connectivity Unified Architecture (OPC-UA) -defined in IEC 62541-. The main objective of this artifacts and architecture is to share the information gathered in real-time from the Electric Power System to many information systems that require it in order to supporting Management, Operational Analysis and other Advanced Functions in the Smart Grid context. The procedure to develop "CIM Wrappers" is showed, as well as results obtained and some conclusions about the works to integrate legacy systems of Comision Federal de Electricidad (CFE) in Mexico.
