Scope

This part of IEC 61850 specifies the logical node classes for use in the domain of hydroelectric power stations, steam and gas turbines.This IEC61850 domain information model standard utilizes the existing Logical Node (LN) classes defined in IEC 61850-7-4 Basic communication structure – Compatible logical node classes and data object classes where possible, while defining new and extended domain specific LN classes to provide the necessary data objects for application to functions and systems in in the domain of hydroelectric power stations, steam and gas turbines. The domain information model includes the interface towards a central operator centre’s control functions.The Scope related to steam and gas turbine specifics is limited to the overall control functions, generator and turbine control functions. For hydroelectric power the scope includes the entire power station automation system.Table 2 shows all attributes of IEC 61850-7-410:2022A namespace.Table 2 – Attributes of IEC 61850-7-410:2022A namespaceAttribute Content Namespace nameplate Namespace Identifier IEC 61850-7-410 Version 2022 Revision A Full Namespace Name IEC 61850-7-410:2022A Full Code Component Name IEC_61850-7-410.NSD.2022A.Full Light Code Component Name IEC_61850-7-410.NSD.2022A.Light Namespace Type domain Namespace dependencies includes IEC 61850-7-4:2007B version :2007 revision :B The Code Components are in light and full version:The full version is named: IEC_61850-7-410.NSD.2022A.Full. It contains definition of the whole data model defined in this standard with the documentation associated and access is restricted to purchaser of this part. The light version is named: IEC_61850-7-410.NSD.2022A.Light. It does not contain any documentation but contains the whole data model as per full version, and this light version is freely accessible on the IEC website for download at: http://www.iec.ch/tc57/supportdocuments, but the usage remains under the licensing conditions.The Code Components for IEC 61850 data models are formatted in compliance with the NSD format defined by the standard IEC 61850-7-7. Each Code Component is a ZIP package containing:the electronic representation of the Code Component itself (possibly multiple files); the grammar files (XSD) enabling to check the consistency of the associated files against the defined version of NSD, but as well against the IEC 61850 flexibility rules in case of private extensions; a file describing the content of the package (IECManifest.xml).The IECManifest contains different sections giving information on:The copyright notice; The identification of the code component; The publication related to the code component; The list of the electronic files which compose the code component; An optional list of history files to track changes during the evolution process of the code component.The life cycle of a code component is not restricted to the life cycle of the related publication. The publication life cycle goes through two stages, Version (corresponding to an edition) and Revision (corresponding to an amendment). A third publication stage (Release) allows publication of Code Component in case of urgent fixes of InterOp Tissues, thus without need to publish an amendment.Consequently new release(s) of the Code Component may be released, which supersede(s) the previous release, and will be distributed through the IEC TC57 web site at: http://www.iec.ch/tc57/supportdocuments.The latest version/release of the document will be found by selecting the file named IEC_61850-7-410.NSD.{VersionStateInfo}.Light with the filed VersionStateInfo of the highest value. Examples on modelling according to IEC61850 in the domain of hydroelectric power stations, steam and gas turbines is found in the IEC technical report IEC TR 61850-7-510.
