IEC's latest update to smart grid standard to support non-english labels also

Toshiba Corporation said renowned standards organization IEC has endorsed a committee draft for vote (CDV) of an International Standard, proposed by Toshiba supporting higher interoperability among subsystems in electricity transmission and distribution (T&D) systems. Toshiba says its proposal compensates for the shortcomings of the CIM. Under CIM, a data file in conformity with the standard integrates information about all the components, hardware and software, of a power grid; but this exists in only one version, precluding individual updates of information on any given component. More profoundly, grid components are defined in Unified Modelling Language (UML), a graphical programming language, and all cross-references among components are made through English labels only. There is a need to extend this to allow people to use the database in their own languages. In this situation, Toshiba proposed a new interface standard (IEC62656-3) that provides a bridge between CIM and the Common Data Dictionary (CDD: IEC61360-4DB), a database managing data-specifications for all electrotechnical products and services. The CDD has already been adopted as one of the "First Set of Consistent Standards" for Smart Grids, and its use is required in the EU under European Standardization Mandate M/490. The proposed interface realizes full version control for individual objects and facilitates easy extension by adopting a tabular database to which columns of an identifier and associated values in multiple languages can be easily added. The Toshiba-based proposal has cleared the enquiry stage and is now at the approval stage, preparing to issue a Final Draft International Standard (FDIS) for the final vote on editorial aspects. Dr. Takashi Kamitake, chief fellow at Toshiba's R&D center who supervised the standardization said, "The standardization will bring great value to the development of the smart grid industry. It will allow us to promote the standardization of related technologies and to contribute to the creation of a global smart grid market."
