Attenuating wind turbine loads through model based individual pitch control

Research output: Chapter in Book/Report/Conference proceedingArticle in proceedingsResearch

Abstract

In this paper we consider wind turbine load attenuation through model based control. Asymmetric loads caused by the wind field can be reduced by pitching the blades individually. To this end we investigate the use of stochastic models of the wind which can be included in a model based individual pitch controller design. In this way the variability of the wind can be estimated and compensated for by the controller. The wind turbine model is in general time-variant due to its rotational nature. For this reason the modeling and control is carried out in so-called multiblade coordinates. The individual pitch controller design in investigated in simulations.
