A control system for a floating offshore wind turbine (FOWT). The FOWT includes a floating base, a tower, a nacelle, and rotor with blades that harvest energy from wind passing the FOWT. Without a rigid support, however, the FOWT is able to move. The controller uses generator speed and platform pitch position of the FOWT as inputs and manipulates blade pitch and torque resistance to achieve stability.

Provided is a method, computing system, and computer program product for reducing floating wind turbine loads induced by ocean waves by adjusting a blade pitch angle of at least one rotor blade of a floating wind turbine to minimize a moment imbalance at a platform top of the floating wind turbine caused by ocean wave activity.

The invention relates to a control method for controlling an offshore floating tower wind turbine and to various systems and a wind turbine that use said method. The invention is mainly based on the control of the pitch angle of the blades of the wind turbine by means of power levels different from rated power, depending on the movement conditions to which the wind turbine is subjected at sea, and for above rated operating conditions wind speed. Owing to the described method, the invention allows the movements experienced by the wind turbine to be reduced, using the energy performance thereof more efficiently, without detriment to the service life thereof.

The present application discloses a supercomputing center system, which includes a wind-powered vessel, and a damping device, at least one supercomputing device, a control device, and a wind power generation device that are arranged on the hull of the wind-powered vessel. The damping device is configured to maintain the stability of the hull; the supercomputing device is configured to perform operations; the control device controls the wind power generation device to generate power and adjusts the angles of the damping device based on real-time sea condition information; and the wind power generation device supplies power to the supercomputing device, the damping device, and the control device.

The nacelle (27) of a horizontal axis wind turbine (WT) is mounted on a vertical support (VS) by means of a pivot (33). The vertical support is mounted off-center with respect to a floating, rotatable support (7). A weight (43) functionally attached to the nacelle maintains the axis of the turbine horizontal as the floating support pitches (rotates forward and back). The weight is attached to an elongate vertical element (41). Relative motion between the vertical element (41) and the pitching floating support (HS) generates an electric current.
