Aero-elastic loads on a 10 MW turbine exposed to extreme events selected from a year-long Large-Eddy Simulation over the North Sea

Abstract. In this article the aero-elastic loads on a 10 MW turbine in response to unconventional wind conditions selected from a year long Large Eddy Simulation on a site at the North Sea are evaluated. Thereto an assessment is made of the practical importance of these wind conditions within an aero-elastic context based on high fidelity wind modelling. Moreover the accuracy of BEM based methods for modelling such wind conditions is assessed. The study is carried out in a joint effort by the Energy Research Centre of the Netherlands ECN part of TNO and the Dutch meteorological consultancy company Whiffle.
