Aeroelastic 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 aeroelastic loads on a 10 MW turbine in response to extreme events (low-level jet, shear, veer and turbulence intensity) selected from year-long large-eddy simulation (LES) site at North Sea are evaluated. These generated with high-fidelity LES wind model fed into an tool using two different aerodynamic models: based blade element momentum (BEM) free vortex wake model. Then calculated compared IEC standards. It was found that all these remain within those of design loads. Moreover, accuracy BEM-based methods for modelling such conditions showed considerable overprediction shear and/or veer.
