Floating Type Shrouded Wind Turbine

Scaled model in experiments and numerical model by Simulink.

This project addresses a fundamental study of a floating type shrouded wind turbine which can augment the wind speed at the rotor plane and improve the wind energy converting efficiency. Several novel concepts are introduced to the system for cost reduction: a revolute hinge is applied between the tower and the nacelle to maintain the orientation of the nacelle even in a large tower inclination, a swashplate mechanism with cyclic control is employed for blade pitch regulation to improve the system controllability, a novel mooring system with a slewing bearing is utilized to let the yawing system be passive, and an advanced spar-type floater is used to obtain high restoring performance with a short spar. The codes on the numerical model, control system, and data analysis are explained.
