Communication networks and systems for power utility automation - Part 7-1: Basic communication structure - Principles and models

IEC 61850-7-1:2011 introduces the modelling methods, communication principles, and information models that are used in the various parts of the IEC 61850-7 series. The purpose is to provide - from a conceptual point of view - assistance to understand the basic modelling concepts and description methods for:  - substation-specific information models for power utility automation systems,  - device functions used for power utility automation purposes, and  - communication systems to provide interoperability within power utility facilities. Compared to the first edition, this second edition introduces:  - the model for statistical and historical statistical data,  - the concepts of proxies, gateways, LD hierarchy and LN inputs,  - the model for time synchronisation,  - the concepts behind different testing facilities,  - the extended logging function. It also clarifies certain items.

Réseaux et systèmes de communication pour l'automatisation des systèmes électriques -- Partie 7-1: Structure de communication de base - Principes et modèles

La CEI 61850-7-1:2011 introduit les méthodes de modélisation, les principes de communication et les modèles d'information qui sont utilisés dans les différentes parties de la série CEI 61850-7-x. La présente partie de la série CEI 61850 a pour objectif de fournir - d'un point de vue conceptuel - une assistance pour comprendre les concepts de modélisation et les méthodes de description de base pour:  - des modèles d'information spécifiques à un poste pour des systèmes d'automatisation d'entreprises de distribution électrique,  - des fonctions de dispositif utilisées à des fins d'automatisation d'entreprises de distribution électrique, et  - des systèmes de communication pour assurer l'interopérabilité au sein des installations des entreprises de distribution électrique. En comparaison à la première édition, cette deuxième édition introduit:  - les concepts de proxy, passerelle, hiérarchie LD et entrées LN,  - les concepts sous-jacents aux différentes installations d'essai,  - la fonction de journalisation étendue. Elle clarifie également certains points.

Komunikacijska omrežja in sistemi za avtomatizacijo porabe (električne) energije - 7-1. del: Osnovna komunikacijska struktura - Načela in modeli

Ta del serije IEC 61850 vpeljuje metode modeliranja, komunikacijska načela in informacijske modele, ki se uporabljajo v različnih delih serije IEC 61850-7-x. Namen tega dela serije IEC 61850 je zagotoviti – s konceptualnega stališča – pomoč pri razumevanju osnovnih konceptov modeliranja in opisnih metod za: - informacijske modele, specifične za razdelilne postaje, za sisteme za avtomatizacijo porabe električne energije; - funkcije naprav, ki se uporabljajo za avtomatizacijo porabe električne energije in – komunikacijske sisteme za zagotavljanje medoperabilnosti v opremi za porabo električne energije. Nadalje ta del serije IEC 61850 podaja razlage in podrobne zahteve v zvezi z odnosom med IEC 61850-7-4, IEC 61850-7-3, IEC 61850-7-2 in IEC 61850-5. Ta del razlaga, kako se abstraktne storitve in modeli serije IEC 61850-7-x vzporejajo s konkretnimi komunikacijskimi protokoli, kot so opredeljeni v IEC 61850-8-1. Koncepti in modeli, ki jih podaja ta del serije IEC 61850, se lahko uporabijo tudi za opis informacijskih modelov in funkcij za: - hidroelektrarne, - izmenjavo podatkov med razdelilnimi postajami; - izmenjavo podatkov za porazdeljeno avtomatizacijo; - izmenjavo podatkov med razdelilno postajo in nadzornim centrom; - izmenjavo podatkov za merjenje; - spremljanje in diagnostiko stanja in – izmenjavo podatkov z inženirskimi sistemi za konfiguracijo naprav.
