Wind turbines - Part 1: Design requirements
Amandma A1:2011 je dodatek k standardu SIST EN 61400-1:2006
This part of IEC 61400 specifies essential design requirements to ensure the engineering integrity of wind turbines. Its purpose is to provide an appropriate level of protection against damage from all hazards during the planned lifetime. This standard is concerned with all subsystems of wind turbines such as control and protection mechanisms, internal electrical systems, mechanical systems and support structures. This standard applies to wind turbines of all sizes. For small wind turbines IEC 61400-2 may be applied. This standard should be used together with the appropriate IEC and ISO standards mentioned in Clause 2.

Vetrne turbine - 1. del: Zahteve za načrtovanje - Dopolnilo A1 (IEC 61400-1:2005/A1:2010)
Amandma A1:2011 je dodatek k standardu SIST EN 61400-1:2006
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.

Add, as 2
As an alternative to the specification of DLC 2.3 above and in Table 2, DLC 2.3 may instead

response simulations shall be carried out for each considered mean wind speed. For each
response simulation, the extreme response after the electrical fault has occurred is sampled.
The fault must be introduced after the effect of initial conditions has become negligible. For
each mean wind speed, a nominal extreme response is evaluated as the mean of the 12
sampled extreme responses plus three times the standard deviation of the 12 samples. The
characteristic response value for DLC 2.3 is determined as the extreme value among the
nominal extreme responses.
7.5 Load calculations
Add, after second paragraph, the following new text:
When turbulent winds are used for dynamic simulations, attention should be given to the grid
resolution regarding the spatial and time resolution.

Concerning the spatial resolution, the maximum distance between adjacent points should be smaller than 25 %
of Λ1 (Equation (5)) and no larger than 15 % of the rotor diameter. This distance is meant to be the diagonal
distance between points in each grid cell defined b
