IEC 61970-552

Abstract

Scope: This part of IEC 61970 specifies the format and rules for exchanging modelling information based upon the CIM. It uses the CIM RDF Schema presented in IEC 61970-501 as the metamodel framework for constructing XML documents of power system modelling information. The style of these documents is called CIMXML format. Model exchange by file transfer serves many useful purposes. Profile documents such as IEC 61970-452 and other profiles in the 61970-45x series of standards explain the requirements and use cases that set the context for this work. Though the format can be used for general CIM-based information exchange, specific profiles (or subsets) of the CIM are identified in order to address particular exchange requirements. The initial requirement driving the solidification of this specification is the exchange of transmission network modelling information for power system security coordination. This part of IEC 61970 supports a mechanism for software from independent suppliers to produce and consume CIM described modelling information based on a common format. The proposed solution: • is both machine readable and human readable, although primarily intended for programmatic access, • can be accessed using any tool that supports the Document Object Model (DOM) and other standard XML application program interfaces, • is self-describing, • takes advantage of current World Wide Web Consortium (W3C) recommendations.
