Floating wind turbine motion suppression using an active wave energy converter Webler Soares, Anderson Ricardo
Abstract
This thesis proposes a new concept of an actively-controlled wave energy converter for suppressing the pitch and roll motions of the floating offshore wind turbines. The wave energy converter consists of several floating bodies which receive the wave energy, actuators which convert the wave energy into electrical energy and generate the mechanical forces, and rigid bars which connect the floating bodies and the wind turbine platform and deliver the actuator forces to the platform. The rotational torques to minimize the platform pitch and roll motions are determined by the linear quadratic regulator, while the determined torques are realized by the actuator forces that maximize the wave power capture. The performance of the proposed wave energy converter in simultaneously suppressing the platform pitch and roll motions and extracting the wave energy is validated in simulations.
