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.

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

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.
