Effects of Induction and Wake Steering Control on Drivetrain Fatigue and Wind Farm Power Production

Power optimization through wake steering and axial induction control is a well investigated topic in wind energy, which is generally proven to work. The influence of control manoeuvres on the fatigue of static components is generally discussed, but drivetrain fatigue due to wake steering and axial induction control is rarely discussed, while it...

Semi-passive trailing-edge flaps: for ultimate and fatigue load reductions on wind turbines

This thesis investigates the potential of a semi-passive trailing-edge flap on a large conceptual wind turbine. The mechanism passively reacts to blade and tower accelerations by changing the airfoil camber, opposing the dynamic loads on the turbine. An active element is present, which influences the mean of the flap oscillation. First, a low...

Structural Study and Parametric Analysis on Fatigue Damage of a Composite Rotor Blade

Fatigue damage calculations are conducted as state-of-art design process for wind turbines. Fatigue analysis is performed on spar caps and trailing edge tape (UD material) considering uni-axial stress state. The main objective of the research project is to analyze the effect of various parameters like yaw errors, wind turbine design load cases...
