Abstract

Thrust force needs to be taken into account in the development of floating type shrouded wind turbines since it would lead to large tower inclination, and both the power conversion efficiency and the safety margin of the system would be reduced. In this study, a novel spar-type shrouded wind turbine using a hinge to mount the nacelle on the tower, which can maintain the nacelle in horizontal state even with large tower inclination, is studied based on a 1:100 model. The characteristics of the wind turbine are studied via wind tunnel experiments and wave basin experiments. In wind tunnel experiments, the wind speed-up performance of the shroud and the self-aligning property of the wind turbine are evaluated. In wave basin experiments, dynamical response of the wind turbine in idling, operational and parked modes are studied. A model-based attitude controller for stabilizing the nacelle is also proposed and the control performance is analyzed based on experimental results.
