IEC 61968-1:2012

Application integration at electric utilities - System interfaces for distribution management - Part 1: Interface architecture and general recommendations

IEC 61968-1:2012 is the first part in a series that, taken as a whole, define interfaces for the major elements of an interface architecture for distribution management. This International Standard identifies and establishes recommendations for standard interfaces based on an Interface Reference Model (IRM). Subsequent clauses of this standard are based on each interface identified in the IRM. This set of standards is limited to the definition of interfaces. They provide for interoperability among different computer systems, platforms, and languages. Methods and technologies used to implement functionality conforming to these interfaces are recommended in IEC 61968-100. This edition includes the following significant technical changes with respect to the previous one:
- update of IRM table which has been out of date;
- addition of missing Advanced Metering Infrastructure (AMI) related functions;
- alignment with newly released IEC documents;
- alignment with IEC 61968-100; update of annexes.

Intégration d'applications pour les services électriques - Interfaces système pour la gestion de distribution - Partie 1: Architecture des interfaces et recommandations générales

La CEI 61968-1:2012 est la première partie d'une série qui, prise dans son ensemble, définit les interfaces pour les éléments principaux d'une architecture d'interface de gestion de la distribution. Cette Norme Internationales identifie et établit des recommandations pour des interfaces standard basées sur un Modèle d'Interface de Référence (IRM). Les articles suivants de cette norme sont basés sur chaque interface identifiée par l'IRM. Cet ensemble de normes se limite à la définition des interfaces. Elles pourvoient à l'interopérabilité entre les différents systèmes informatiques, plates-formes, et langages. Les processus et les technologies utilisés pour mettre en application une fonctionnalité se conformant à ces interfaces sont recommandés par la CEI 61968-100. Cette édition inclut les modifications techniques majeures suivantes par rapport à la précédente:
- mise à jour du tableau intitulé Modèle d'interface de référence (IRM);
- ajout des fonctions manquantes relatives à l'infrastructure de comptage avancée (AMI);
- alignement avec les documents de la CEI récemment publiés;
- alignement avec le contenu de la CEI 61968-100;
- mise à jour des annexes.

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations
