Abstract
A controller for a floating wind turbine is adapted to cause the wind turbine to extract energy from wave-induced motion of the turbine. The controller controls the rotor speed of the turbine by controlling the torque of the load presented to the rotor such that the rotor speed varies in response to wave-induced motion.
Claims27
A controller for a floating wind turbine, the controller being adapted to cause the wind turbine to extract energy from wave-induced motion of the turbine, wherein the controller controls the rotor speed of the turbine by controlling the torque of the load presented to the rotor such that the rotor speed varies in response to wave-induced motion.
A floating wind turbine structure comprising a buoyant tower having a wind turbine mounted thereto and a controller, the wind turbine being arranged to drive a load which presents a torque thereto and being adapted to extract energy from wave-induced motion of the turbine, wherein the controller controls the rotor speed of the turbine by controlling the torque of the load such that the rotor speed varies in response to wave-induced motion.
A method of controlling a floating wind turbine such that the wind turbine extracts energy from wave-induced motion of the turbine, wherein the rotor speed of the turbine is controlled by controlling the torque of the load presented to the rotor such that the rotor speed varies in response to wave-induced motion.
A software product comprising instructions which when executed by a processor cause the processor to control a floating wind turbine structure such that the wind turbine extracts energy from wave-induced motion of the turbine, wherein the rotor speed of the turbine is controlled by controlling the torque of the load presented to the rotor such that the rotor speed varies in response to wave-induced motion.
A method of manufacturing a software product which is in the form of a physical carrier, comprising storing on the data carrier instructions which when executed by a processor cause the processor to control a floating wind turbine structure such that the wind turbine extracts energy from wave-induced motion of the turbine, wherein the rotor speed of the turbine is controlled by controlling the torque of the load presented to the rotor such that the rotor speed varies in response to wave-induced motion.
