IEC 61850-7-4:2010

Communication networks and systems for power utility automation - Part 7-4: Basic communication structure - Compatible logical node classes and data object classes

IEC 61850-7-4:2010 specifies the information model of devices and functions generally related to common use regarding applications in systems for power utility automation. It also contains the information model of devices and function-related applications in substations. In particular, it specifies the compatible logical node names and data object names for communication between intelligent electronic devices (IED). This includes the relationship between logical nodes and data objects. Major technical changes with regard to the previous edition are as follows:
- corrections and clarifications according to technical issues raised by the users' community; extensions for new logical nodes for the power quality domain;
- extensions for the model for statistical and historical statistical data;
- extensions regarding IEC 61850-90-1;
- extensions for new logical nodes for monitoring functions according to IEC 62271;
- new logical nodes from IEC 61850-7-410 and IEC 61850-7-420 of general interest.
This publication is of core relevance for Smart Grid.

Réseaux et systèmes de communication pour l'automatisation des systèmes électriques - Partie 7-4: Structure de communication de base - Classes de noeuds logiques et classes d'objets de données compatibles

IEC 61850-7-4:2010 spécifie le modèle d'information des dispositifs et les fonctions généralement liées à l'usage commun concernant les applications dans des systèmes pour l'automatisation des entreprises de distribution d'électricité. Elle contient le modèle d'information de dispositifs et les applications liées aux fonctions dans les postes. En particulier, elle spécifie les noms de nœuds logiques compatibles et les noms d'objets de données pour la communication entre des dispositifs électroniques intelligents (IED). Cela comprend la relation entre nœuds logiques et objets de données. Les modifications techniques majeures par rapport à l'édition précédente sont les suivantes:
• corrections et clarifications en accord avec la lettre d'information "IEC 61850-technical issues by the IEC TC 57" (voir le document 57/963/INF, 2008-07-18);
• extensions pour les nouveaux nœuds logiques du domaine de la qualité de l'énergie électrique fournie;
• extensions pour le modèle de données statistiques et historiques;
• extensions par rapport à l'IEC 61850-90-1 (communications poste à poste);
• extensions pour les nouveaux nœuds logiques pour les fonctions de surveillance en accord avec l'IEC 62271;
• nouveaux nœuds logiques des IEC 61850-7-410 et IEC 61850-7-420 d'intérêt général.
