Wind energy generation systems - Part 50: Wind measurement - Overview
IEC 61400-50:2022 provides a general introduction to the options that are available for wind measurement, which are further detailed in the other parts of the IEC 61400-50 series. Tandis que ces autres normes définissent les cas d’utilisation relatifs aux mesurages du vent, la série IEC 61400-50 établit des exigences de mesure du vent qui sont indépendantes des cas d’utilisation. Son objectif est d’assurer que les mesurages du vent et l’évaluation des incertitudes (relative à ces mesurages) sont effectués de manière cohérente dans tout le secteur éolien; et d’assurer que ces mesurages du vent sont effectués de telle sorte que les incertitudes pouvant être quantifiées soient dans une plage acceptable. This first edition of IEC 61400-50 is part of a structural revision that cancels and replaces the performance standards IEC 61400-12-1:2017 and IEC 61400-12-2:2013. The structural revision contains no technical changes with respect to IEC 61400-12-1:2017 and IEC 61400-12-2:2013, but the parts that relate to wind measurements, measurement of site calibration and assessment of obstacle and terrain have been extracted into separate standards.

Systèmes de génération d’énergie éolienne – Partie 50: Mesurage du vent - Vue d'ensemble
IEC 61400-50:2022 fournit une introduction générale aux options de mesure du vent disponibles, avec de plus amples informations dans les autres parties de la série IEC 61400‑50. Whereas those other standards define use-cases for wind measurements, the IEC 61400-50 series sets those wind measurement requirements which are independent of the use-case. Its purpose is to ensure that wind measurements and the evaluation of uncertainties in those measurements are carried out consistently across the wind industry and that wind measurements are carried out such that the uncertainties can be quantified and that those uncertainties are within an acceptable range. La présente première édition de l’IEC 61400-50 fait partie d’une révision structurelle qui annule et remplace les normes de performance IEC 61400-12-1:2017 et IEC 61400-12-2:2013. Cette révision structurelle ne contient aucune modification technique par rapport à l'IEC 61400-12-1:2017 et l'IEC 61400-12 2:2013. Toutefois, les parties relatives aux mesurages du vent, au mesurage de l'étalonnage du site et à l'évaluation des obstacles et du terrain ont été extraites vers des normes distinctes.

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.
IEC 61400-50 has been prepared by IEC technical committee 88: Wind energy generation
systems. It is an International Standard.
This first edition of IEC 61400-50 is part of a structural revision that cancels and replaces the
performance standards IEC 61400-12-1:2017 and IEC 61400-12-2:2013. The structural revision
contains no technical changes with respect to IEC 61400-12-1:2017 and IEC 61400-12-2:2013,
but the parts that relate to wind measurements, measurement of site calibration and assessment
of obstacle and terrain have been extracted into separate standards.
The purpose of the re-structure was to allow the future management and revision of the power
performance standards to be carried out more efficiently in terms of time and cost and to provide
a more logical division of the wind measurement requirements into a series of separate
standards which could be referred to by other use-case standards in the IEC 61400 series and
subsequently maintained and developed by appropriate experts.

INTRODUCTION
The purpose of the IEC 61400-50 series of standards is to provide uniform methodologies and
requirements that will ensure consistency, accuracy and reproducibility in the measurement of
the wind. In creating the IEC 61400-50 series of standards, a distinction is now made between
the method of measurement of the wind and the various "use-cases" in other parts of IEC 61400
in which those wind measurements are applied (e.g. power performance, noise measurement,
load measurement, resource assessment). It is anticipated that the IEC 61400-50 series of
standards will be applied by:
a) wind turbine manufacturers testing prototype or serial production turbines with the aim of
determining or verifying aspects of the turbine specification where the measured wind is a
necessary input (e.g. power performance, noise, structural loads);
b) wind measurement equipment manufacturers providing instruments, meteorological masts
and mounting hardware to the wind industry;
c) organizations and laboratories providing wind measurement instrumentation calibration
services;
d) technical consultants delivering wind measurement services to wind turbine manufacturers,
wind farm developers and operators, etc.;
e) wind turbine operators who need to verify that stated or required specifications are met and
which require wind measurements as an input;
f) other committees developing standards in the IEC 61400 series which make reference to
the specification of equipment and methods to be used in the measurement of the wind.
This series of related standards provides guidance in the wind measurement methods,
equipment, classification, calibration and uncertainty assessment t
