Abstract
Wind turbines, which are installed under the natural wind conditions, suffer complicated loads on the rotor blades due to the turbulent wind. The present paer describes a numerical method for calculating the effects of turbulence characteristics on the aerodynamic loads, and shows the numerical results. The turbulent wind field for the present calculation is simulated with the Veer's model, which is based on a Fourier synthesis method and capable of considering spatial cross-correlations between any two points in the rotor plane, where the turbulent wind is generated. An inviscid aerodynamic model based on an asymptotic acceleration potential method is adopted for the calculation of aerodynamic loads on the rotor blades.
