EN 61400-1:2005

Wind turbines - Part 1: Design requirements

Deals with safety aspects, quality assurance and engineering integrity, and specifies safety requirements for design, installation and operation of wind turbine generator systems.

Windenergieanlagen - Teil 1: Auslegungsanforderungen

Eoliennes - Partie 1: Exigences de conception

Traite des aspects relatifs à la sécurité, à l'assurance de la qualité et à l'intégrité, et spécifie les prescriptions de sécurité, de la conception, de l'installation et de l'exploitation des aérogénérateurs.

Vetrne turbine – 1. del: Zahteve za načrtovanje (IEC 61400-1:2005)

Ta del IEC 61400 določa osnovne zahteve za načrtovanje, da se zagotovi neoporečnost strojegradnje vetrnih turbin. Njegov namen je zagotoviti primerno raven varstva pred škodo, ki jo lahko  povzročijo vse nevarnosti med načrtovano življenjsko dobo. Ta standard zadeva vse podsisteme vetrnih turbin, kot so mehanizmi nadzora in varovanja, notranji električni sistemi, mehanski sistemi in podporne strukture. Ta standard velja za vetrne turbine vseh velikosti. Za majhne vetrne turbine se lahko uporabi IEC 61400-2. Ta standard se uporablja skupaj s primernimi standardi IEC in ISO, omenjenimi v klavzuli 2.

This European Standard was approved by CENELEC on 2005-10-01. CENELEC members are bound to
comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this European
Standard the status of a national standard without any alteration.

Up-to-date lists and bibliographical references concerning such national standards may be obtained on
application to the Central Secretariat or to any CENELEC member.

This European Standard exists in three official versions (English, French, German). A version in any other
language made by translation under the responsibility of a CENELEC member into its own language and
notified to the Central Secretariat has the same status as the official versions.

CENELEC members are the national electrotechnical committees of Austria, Belgium, Cyprus, Czech
Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia,
Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia, Spain, Sweden,
Switzerland and United Kingdom.

Foreword
The text of document 88/228/FDIS, future edition 3 of IEC 61400-1, prepared by IEC TC 88, Wind
turbines, was submitted to the IEC-CENELEC parallel vote and was approved by CENELEC as
EN 61400-1 on 2005-10-01.
This European Standard supersedes EN 61400-1:2004.
The main changes with respect to EN 61400-1:2004 are listed below:
– the title has been changed to “Design requirements” in order to reflect that the standard presents
safety requirements rather than requirements for safety or protection of personnel;
– wind turbine class designations have been adjusted and now refer to reference wind speed and
expected value of turbulence intensities only;
– turbulence models have been expanded and include an extreme turbulence model;
– gust models have been adjusted and simplified;
– design load cases have been rearranged and amended;
– the inclusion of turbulence simulations in the load calculations is emphasized and a scheme for
extreme load extrapolation has been specified;
– the partial safety factors for loads have been adjusted and simplified;
– the partial safety factors for materials have been amended and specified in terms of material
types and component classes;
– the requirements for the control and protection system have been amended and clarified in terms
of functional characteristics;
– a new clause on assessment of structural and electrical compatibility has been introduced with
detailed requirements for assessment, including information on complex terrain, earthquakes and
wind farm wake effects.
The following dates were fixed:
– latest date by which the EN has to be implemented
at national level by publication of an identical
national standard or by endorsement (dop) 2006-07-01
– latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2006-11-01
Annex ZA has been added by CENELEC.
