IEC 61400-25-3:2015

Wind turbines - Part 25-3: Communications for monitoring and control of wind power plants - Information exchange models

IEC 61400-25-3:2015 specifies an abstract communication service interface describing the information exchange between a client and a server for:
- data access and retrieval,
- device control,
- event reporting and logging,
- self-description of devices (device data dictionary),
- data typing and discovery of data types.
Main changes with respect to the previous edition consist of:
- harmonization with newer editions of IEC 61850 standards;
- reduction of overlap between standards and simplification by increased referencing, etc.

Eoliennes - Partie 25-3: Communications pour la surveillance et la commande des centrales éoliennes - Modèles d'échange d'information

L'IEC 61400-25-3:2015 spécifie une interface abstraite pour les services de communication qui décrit l'échange d'information entre un client et un serveur pour:
- l'accès et la récupération des données,
- la commande des dispositifs,
- les rapports et journalisations d'événements,
- l'autodescription des dispositifs (dictionnaire de données de dispositif),
- l'établissement de types de données et la découverte de types de données. Cette nouvelle édition comporte les changements importants suivants par rapport à l'édition précédente:
- l'harmonisation avec de nouvelles éditions de la série IEC 61850;
- la réduction de l'écart entre les normes et la simplification par un référencement amélioré, etc.

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.
