Samenvatting:
An aeroelastic wind turbine optimization code has been developed andapplied in practice. The code iteratively calls a wind turbine time simulation package to determine the aeroelastic behaviour of the design. A new aerodynamic and structural rotor design, optimised for minimum cost of generated energy, has been established. The maximization of energy yield has been balanced with the minimization of the fatigue loading on the tower and on the blades. The aeroelastic optimization has resulted in 10% reduction of the fatigue loads, leading to a 6% reduction of the blade and tower costs and a 1% lower cost of generated energy compared with a stationary optimised rotor. Due to the limited scope of the case study larger reductions of loads and costs will be possible. 4 figs., 2 tabs., 6 refs.
