Wind turbines - Part 25-6: Communications for monitoring and control of wind power plants - Logical node classes and data classes for condition monitoring (IEC 61400-25-6:2016)
This part of IEC 61400-25 specifies the information models related to condition monitoring for
wind power plants and the information exchange of data values related to these models.
NOTE Conformance to IEC 61400-25-6 presupposes in principle conformance to IEC 61400-25-2, IEC 61400-25-3
and IEC 61400-25-4.
Figure 2 illustrates the information flow of a system using condition monitoring to perform
condition based maintenance. The figure illustrates how data values are refined and
concentrated through the information flow, ending up with the ultimate goal of condition based
maintenance; actions to be performed via issuing work orders to maintenance teams in order
to prevent the wind power plant device to stop providing its intended service.

La présente norme doit être utilisée avec d'autres normes de la série CEI 61400-25. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
- restructuration majeure du modèle de données afin d’obtenir la flexibilité necessaire
- le format UFF58 n’est plus utilise.
- l’accès aux données utilise désormais les fonctions normalisées d’établissement de rapports et de journalisation
- les recommandations concernant la création de noms de données afin d’obtenir la flexibilité nécessaire

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 itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
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 61400-25-6 has been prepared by IEC technical committee 88:
Wind energy generation systems.
This second edition cancels and replaces the first edition published in 2010. This edition
constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) Major restructuring of the datamodel to accommodate needed flexibility.
b) UFF58 format is no longer used.
c) Access to data is now using the standard reporting and logging functions.
d) Recommendations for creating datanames to accommodate needed flexibility have been
defined.

Wind turbines and Wind energy generation systems can be found on the IEC website.
The committee has decided that the contents of this document will remain unchanged until the
stability date indicated on the IEC website under "http://webstore.iec.ch" in the data related to
the specific document. At this date, the document will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.
A bilingual version of this publication may be issued at a later date.

INTRODUCTION
The IEC 61400-25 series defines information models and information exchange models for
monitoring and control of wind power plants. The modelling approach (for information models
and information exchange models) of IEC 61400-25-2 and IEC 61400-25-3 uses abstract
definitions of classes and services such that the specifications are independent of specific
communication protocol stacks, implementations, and operating systems. The mapping of
1
these abstract definitions to specific communication profiles is defined in IEC 61400-25-4 .
This document defines an information model for condition monitoring information and explains
how to use the existing definitions of IEC 61400-25-2 as well as the required extensions in
order to describe and exchange information related to condition monitoring of wind turbines.
The models of condition monitoring information defined in this document may represent
information provided by sensors or by calculation.
In the context of this document, condition monitoring means a process with the purpose of
observing components or structures of a wind turbine or wind power plant for a period of time
in order to evaluate the state of the components or structures and any changes to it, in order
to detect early indications of impending failures. With the objective to be able to monitor
components and structures recorded under approximately the same conditions, this document
introduces the operational state bin concept. The operational state bin concept is
multidimensional in order to fit the purpose of sorting complex operational conditions into
comparable circumstances.
Condition monitoring is most frequently used as a predictive or condition-based maintenance
technique (CBM). However, there are other predictive maintenance techniques that can also
be used, including the use of the human senses (look, listen, feel, smell) or machine
performance monitoring techniques. These could be considered to be part of the condition
monitoring.
Condition monitoring techniques
Condition monitoring techniques that generate information to be modelled include, but are not
limited to, measured or processed values such as:
a) vibration measurements and analysis;
b) oil debris measurement and analysis;
c) temperature measurement and analysis;
d) strain gauge measurement and analysis;
e) acoustic measurement and analysis.
Components and structures can be monitored by using automatic measurement retrieval or
via a manual process.
Condition monitoring devices
The condition monitoring functions may be located in different physical devices. Some
information may be exposed by a turbine controller device (TCD) while other information may
be exposed by an additional condition monitoring device (CMD). Various actors may request
to exchange data values located in the TCD and/or CMD. A SCADA device may request data
values from a TCD and/or CMD; a CMD may request data values from a TCD. The information
exchange between an actor and a device in a wind power plant requires the use of
information exchange services as defined in IEC 61400-25-3. A summary of the above is
shown in Figure 1.
