Abstract

There is described a control system (170) for stabilizing a floating wind turbine (100), the control system (170) comprising: detection means (271, 272, 273, 274) configured for monitoring an offset (231) from a predetermined floating body pitch angle (393) of the floating wind turbine (100) and / or an offset from a predetermined floating body yaw angle of the floating wind turbine (100), the detection device (271, 272, 273, 274) is further configured for monitoring an oscillating movement (396) of a floating body pitch angle (392) and / or an oscillating movement of a floating body yaw angle, where the predetermined floating body pitch angle (393) and the predetermined floating body yaw angle define a predetermined equilibrium state of the floating wind turbine (100), where the predetermined equilibrium state of the floating wind turbine (100) is determined by the detection device (271, 272, 273, 274). The threshold value (394, 395) of the oscillating motion (396) of the floating body pitch angle (392) and the threshold value of the oscillating motion of the floating body yaw angle further define the predetermined equilibrium state of the floating wind turbine (100); and an actuating device (281, 282) which is designed to actuate the floating body pitch angle (392) and / or the floating body yaw angle until the predetermined equilibrium state is fulfilled, the actuating device (281, 282) being further designed to actuate the oscillating movement (396) of the floating body pitch angle (392) and / or the oscillating movement of the floating body yaw angle until the predetermined equilibrium state is fulfilled, the actuating device (281, 282) being designed to actuate the oscillating movement (396) of the floating body pitch angle (392) and / or the oscillating movement of the floating body yaw angle (392) until the predetermined equilibrium state is fulfilled. Until the predetermined equilibrium state of the floating wind turbine (100) is satisfied. Furthermore, a floating wind turbine (100) is described. In addition, a method for stabilizing a floating wind turbine (100) is described.

Description

technical field [0001] The invention relates to a control system for stabilizing a floating wind turbine. Furthermore, the invention relates to a floating wind turbine and a method for stabilizing a floating wind turbine. Background technique [0002] In the technical field of floating wind turbines, it is known that floating wind turbines may be subject to additional movements due to the additional degrees of freedom compared to conventional wind turbines. This additional movement can cause severe loads on the floating wind turbine and a drop in annual electricity production. For example, if the floating body pitches, the shear forces at the interface between the tower and the nacelle may increase due to the increased gravity load. Furthermore, for the rod-type buoy floating body concept of floating wind turbines, the conventional closed-loop speed-pitch control of the drive train may lead to instability of the floating body's pitch motion. This may be due to the disturb...
