IEC 61850-7-410:2026 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. This third edition cancels and replaces the second edition published in 2012 and Amendment 1:2016. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) New concepts and constructs for modelling of large power generation; b) Addition of new Logical Nodes to cover systems and details of the power generation domain previously not modelled in a sufficient way; c) Review of existing Logical Nodes concerning structure, use of Common Data Classes and naming; d) Fixes and improvements of some names and descriptions of Data Objects; e) Improvements of the structure and enumerations within the Domain Logical Nodes; f) Addition of new Logical Nodes with respect to maintenance and supervision functionality; g) Updating of Logical Nodes for PSS functionality (LNs: APSS, APST and APSF) reflecting the updated PSS standard IEEE 421.5:2016; h) Incorporation of Amendment 1, including among other things the Group E Logical Nodes; i) Resolutions to all known UML Issues related to IEC 61850-7-410; j) This 3rd edition is autogenerated from the UML file; k) Upon publication the updated IEC 61850-7-410 NameSpace will be made available as a Code Component on the TC57 web page. In the Edition 3 of this document, a new modelling approach is applied. In order to achieve greater efficiency and harmonization of the IEC 61850 information model by streamlining the Namespaces it is divided into, the structure of the latest revisions of the Namespaces related to the power generation domain, aims to: – share common concepts, approaches, and models in the generation domains, – increase the modularity of the model itself and enable its extension. This edition hence introduces a new modeling approach, which is further explained in Clause 5. The pillars upon which the new approach is founded are as follows: – a layered architecture for the power station model, in accordance with the control hierarchy concepts defined in IEC 60050-351-55; – a comprehensive review of the models considering the approach outlined in IEC 61850-7-420:2021, aimed at harmonizing fundamental concepts in the power generation domain; – a systematic alignment with the concepts outlined in IEC 61850-7-500:2017. Specific aspects typical of the large power generation domain are also addressed in the present document. The relationship between concepts described in this document and the ones of related standards can be found in Annex B and Annex C. In addition to this objective, Edition 3 provides clarifications on the purposes and intended use of such information model in a new set of explanatory clauses, which were not present in the previous editions. IEC 61850-7-410:2026 specifie les classes de nouds logiques a utiliser dans le domaine des centrales hydroelectriques, des centrales electriques a turbine a vapeur et des centrales electriques a turbine a gaz. La presente norme IEC 61850 de modele d’informations de domaine utilise dans la mesure du possible les classes de nouds logiques (LN, Logical Node) existantes definies dans l’IEC 61850-7-4, Structure de communication de base – Classes de nouds logiques et classes d’objets de donnees compatibles, tout en definissant de nouvelles classes LN, etendues et specifiques a un domaine, afin de fournir les objets de donnees necessaires pour une transposition aux fonctions et systemes dans le domaine des centrales hydroelectriques, des centrales electriques a turbine a vapeur et des centrales electriques a turbine a gaz. Le modele d’informations de domaine inclut une interface avec les fonctions de commande associees a un centre des operateurs. Le domaine d’application du present document, relatif aux specificites des turbines a vapeur et a gaz est limite aux fonctions de commande globales, et aux fonctions de commande du generateur et de la turbine. Pour la production hydroelectrique, le domaine d’application englobe l’ensemble du systeme d’automatisation de la centrale electrique. L’Edition 3 est destinee a constituer une base, a associer a des extensions pour des mises en ouvre locales. De telles extensions peuvent etre definies dans des profils. Bon nombre des nouds logiques definis dans le present document sont concus pour pouvoir etre utilises dans des domaines autres que les centrales hydroelectriques et les turbines a vapeur et a gaz. Une proposition de structure des nouds logiques en paquets pour integration avec d’autres domaines est fournie dans l’Annexe G (informative), Migration du present document vers la future edition de l’
