Endorsement notice
The text of the International Standard IEC 61400-1:1999 was approved by CENELEC as a European
Standard with agreed common modifications as given below.
COMMON MODIFICATIONS
Introduction
Replace the first existing paragraph by:
The standard contains some requirements for a safe operation of wind turbine generator systems falling
in the scope of Article 118a of the EC Treaty. Users of this Standard should, with the respect to these
requirements, be aware that standards have no formal legal relationship with Directives which may have
been made under Article 118a of the Treaty. In addition, national legislation in the Member states may
contain more stringent requirements than the minimum requirements of a Directive based on Article 118a.
Information on the relationship between the national legislation implementing Directives based on
Article 118a and this Standard may be given in a national foreword of the national standard implementing
this Standard.
1.1 Scope
Add the following fifth paragraph:
The standard contains requirements which directly address the operator of wind turbine generator
systems. These requirements for a safe operation, however, constitute recommendations for the
manufacturer, designed to support him in drafting the operation instruction handbook.
6.3.2.1 Extreme wind speed model (EWM)
Replace the whole subclause by the following:
The EWM shall be either a steady or a turbulent wind model. The wind models shall be based on the
reference wind speed, V , and a fixed turbulence standard deviation σ .
ref 1
For the steady extreme wind model, the 50 year extreme wind speed V and the one year e
