IEC 61968-13:2008

Application integration at electric utilities - System interfaces for distribution management - Part 13: CIM RDF Model exchange format for distribution

IEC 61968-13:2008 specifies the format and rules for exchanging modelling information based upon the Common Information Model ("CIM") and related to distribution network data. Allows the exchange of instance data in bulk. Thus, the imported network model data should be sufficient to allow performing network connectivity analysis, including network tracing, outage analysis, load flow calculations, etc. This standard could be used for synchronizing geographical information system databases with remote control system databases.

Intégration d'applications pour les services électriques - Interfaces systèmes pour la gestion de la distribution - Partie 13: Format d'échange du modèle CIM RDF pour la distribution

La CEI 61968-13:2008 spécifie le format et les règles pour l'échange d'informations de modélisation sur la base du CIM (Common Information Model) et en rapport avec des données de réseau de distribution. Permet l'échange de données d'instance en masse. Ainsi, il convient que les données de modèles de réseau importées soient suffisantes pour permettre d'accomplir l'analyse de connectivité de réseau, y compris le suivi de réseau, l'analyse d'interruptions de service, les calculs de flux de charge, etc. La présente partie pourrait être utilisée pour synchroniser des bases de données de systèmes d'informations géographiques avec des bases de données de systèmes de conduite à distance.

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 liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 61968-13 has been prepared by IEC technical committee 57:
Power systems management and associated information exchange.
The text of this standard is based on the following documents:
FDIS Report on Voting
57/930/FDIS 57/955/RVD
Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.

The committee has decided that the contents of this publication will remain unchanged until

the maintenance result date indicated on the IEC web site under "http://webstore.iec.ch" in

the data related to the specific publication. At this date, the publication will be

• reconfirmed;

INTRODUCTION
The IEC 61968 series of standards is intended to facilitate inter-application integration as

opposed to intra-application integration. Intra-application integration is aimed at programs in

the same application system, usually communicating with each other using middleware that is

embedded in their underlying runtime environment, and tends to be optimized for close, real-

time, synchronous connections and interactive request/reply or conversation communication

models. IEC 61968, by contrast, is intended to support the inter-appl
