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(E) 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.

Réseaux et systèmes de communication pour l’automatisation des systèmes électriques - Partie 7-4 : Structure de communication de base - Classes de nœud logique et classes de donnée objet 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.

Komunikacijska omrežja in sistemi za avtomatizacijo porabe (električne) energije - 7-4. del: Osnovna komunikacijska struktura - Združljivi logični vozliščni in podatkovni razredi (IEC 61850-7-4:2010)

Ta del IEC 61850 določa informacijski model naprav in funkcij, običajno povezanih s splošno uporabo glede na uporabe v sistemih za avtomatizacijo porabe (električne) energije.  Prav tako vsebuje informacijski model naprav in funkcijsko povezanih uporab v razdelilnih postajah. Zlasti določa logična vozliščna imena in imena podatkovnih objektov za komunikacijo med inteligentnimi elektronskimi napravami (IED). To vsebuje razmerje med logičnimi vozlišči in podatkovnimi objekti. Imena logičnih vozlišč in podatkovnih objektov, določenih v tem dokumentu, so del modela razredov, predstavljenega v IEC 61850-7-1 in določenega v IEC 61850-7-2. Imena, določena v tem dokumentu, se uporabljajo za izgradnjo hierarhičnih referenčnih objektov uporabljenih za komunikacijo z IED v sistemih za avtomatizacijo porabe (električne) energije in zlasti z IED v razdelilnih postajah in v razdelilnih glavnih dovodnih kablih. V tem delu veljajo konvencije poimenovanja iz IEC 61850-7-2. Da se izognemo zasebnim, nekompatibilnim priponam, ta del določa normativna pravila poimenovanja za večkratne instance in zasebne, kompatibilne pripone razredov logičnih vozlišč (LN) in imen podatkovnih objektov. Vsaka definicija je osnovana na IEC 61850 ali na referenčnih dobro dokumentiranih javnih dokumentov. Ta del ne zagotavlja vadbenega materiala. Priporočeno je najprej prebrati dele IEC 61850-5 in IEC 61850-7-1, skupaj z IEC 61850-7-3 in IEC 61850-7-2. Ta standard se uporablja za opis modelov naprav in funkcij razdelilnih postaj in opreme glavnih dovodnih kablov. Koncepti, določeni v tem standardu, prav tako veljajo za opisovanje modelov naprav in funkcij za:
- izmenjavo podatkov razdelilne postaje do razdelilne postaje,
- izmenjavo podatkov razdelilne postaje do nadzornega centra,
- izmenjavo podatkov elektrarne do nadzornega centra,
- izmenjavo podatkov za porazdeljeno proizvodnjo,
- izmenjava podatkov za porazdeljeno avtomatizacijo ali
- izmenjavo podatkov za merjenje.
