“…To simplify this stage of the analysis, loads were obtained for the averaged flow conditions within each flow speed bin and this is combined with the flow speed occurrence to obtain long-term loading. This follows the approach of Veers [55] and provides a consistent approach to compare between alternative predictions and measurements. When the model through-life loading predictions are compared to the measurements, they underestimate the loads by 30-32% for the Telemac RANS and by 8-16% for the Telemac LES.…”

“…Joint random generation of multiple correlated stationary processes from their spectral representation dates back to the work of Shinozuka 13 and has become a standard method used in a variety of applications where multiple stochastic inputs are correlated in space, such as seismic vibrations or wind 14 . Veers 15 adapted it to wind energy, initiating the current approach of precomputing turbulent boxes propagated through the rotor at simulation time under Taylor's frozen‐turbulence assumption. The method relies on Cholesky factorisation and random phases to come up with a turbulent box realisation that satisfies spectral properties fitted from field measurements.…”

“…Two stall models are available in hGAST, the ONERA [7] and the Beddoes-Leishman [6] model. A separate module that provides turbulent inflow boxes is also available, formulated on the basis of Veers' model [21]. For the calculation of the turbulent inflow wind time series either the von Karman or the Kaimal spectra, specified in the IEC 61400-1 standard, can be used.…”
