1.1 General

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 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 of this document, related to steam and gas turbine specifics, is limited to overall control functions and generator and turbine control functions. For hydroelectric power, the scope includes the entire power station automation system.

Edition 3 is intended to form a basis for extensions in local implementations. Such extensions may be defined in profiles. Many of the Logical Nodes defined in this document are designed to be suitable for use in domains beyond the scope of hydro power plants and steam and gas turbines. A suggested structure of the Logical Nodes into packages for integration with other domains is provided in Annex G (informative), Migration of this document to the future edition of IEC 61850.

1.2 Published versions of the standard and related namespace names

Table 2 provides a reference between all published editions, amendments or corrigenda of this document and the full name of the namespace.

1.3 Identification of the Code Component(s)

1.4 Code Component distribution

Each Code Component is a .zip package containing the electronic representation of the Code Component itself, with a file describing the content of the package (IECManifest.xml).

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 releases of the Code Component may be released, which supersede the previous releases, and will be distributed through the IEC TC57 web site at:

https://www.iec.ch/tc57/supportdocuments

The latest version/release of a Code Component will be found by selecting the file for the Code Component with the highest value for VersionStateInfo, e.g. IEC_61850-7-410.NSD.{VersionStateInfo}.full.zip.

For conformance testing, implementations should always use the latest downloadable Code Components, as the Code Components may be subject to updates. See technical corrigenda and XSD history files.

When the Code Components associated with this document have a full version and a light version, the light version is freely accessible.

When the Code Components associated with this document have a full version only, the full version is freely accessible.

The freely accessible Code Components are available on the IEC website for download at https://www.iec.ch/tc57/supportdocuments, but the usage remains under the licensing conditions.

1.5 Application of the logical node classes

Examples of modelling according to IEC 61850 in the domains of hydroelectric power stations, steam and gas turbines are found in IEC TR 61850‑7‑510, Basic communication structure - Hydroelectric power plants, steam and gas turbines - Modelling concepts and guidelines. In that Technical Report, examples are given showing how to use the model for hydroelectric power plants, steam and gas turbines in a Reference Designation System according to, for example, ISO/IEC 81346.
