Abstract

In the present paper the influence of natural variations in turbulence, wind shear and air density on the fatigue damage equivalent loads during power production are investigated. In site suitability analysis it is normally assumed that the fatigue loads can be estimated based on a 90% quantile for the turbulence and average values for the wind shear and air density. The analysis in the present paper shows that wind shear variations can have a significant influence on fatigue loads for some wind turbine sensors (components). The natural variation in shear should therefore be taken into account in site suitability analysis. The paper shows that this can be done with reasonable accuracy by using the 75% quantile. However, care should be taken since low and negative wind shears can increase the fatigue loads for some wind turbine sensors which may be handled by use of the 25% quantile.
