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...

Inflow conditions resulting in atypical wind turbine fatigue loading

This master’s thesis project related inflow conditions to atypical fatigue loading of wind turbines. The research was fully based on experimental data obtained in another project. First an expected fatigue loading was defined based on the mean wind speed and the turbulence intensity. Differences between expected and measured fatigue loading were...

Increased Energy Yield using the Smart Rotor: Sizing and Control of Trailing Edge Flaps on a Smart Rotor for Maximum Power Generation in Low Fatigue Wind Regimes

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...

Optimising the Design of a Steel Substructure for Offshore Wind Turbines in Deeper Waters

In the need for more green energy a prominent role is reserved for wind energy. Offshore wind energy in deeper waters capitalises on more efficient wind properties and increased public acceptance compared to onshore wind energy and wind farms close to shore. In the coming years the offshore wind market is expected to evolve rapidly, especially...
