Effects of aeroelastic tailoring on performance characteristics of wind turbine systems

The performance characteristics of the wind turbine systems are assessed and compared in terms of power production, load alleviation and pitch system considerations. The blade with both couplings displays scope for potential increases in energy yield. Additionally, beneficial flapwise load alleviation is demonstrated by the adaptive blades from both International Electrotechnical Commission prescribed fatigue, and extreme operational gust analysis. Finally, the adaptive blades display power smoothing capabilities and reductions in pitch rate, however, increases in blade root torsional moment possibly contrast these pitch system benefits.
