20100045038 | Method for the Damping of Tower Oscillations in Wind Power Installations - A method for controlling a wind turbine installation for the damping tower oscillations, in particular a buoyant wind turbine installation comprising a buoyant body, a tower arranged over the buoyant body, a generator mounted on the tower that is rotatable in relation to the wind direction and fitted with a wind turbine, and an anchor line arrangement connected to anchors or foundations on the sea bed. The tower oscillations are damped by the control with the blade angle controller in the constant power or RPM range of the wind turbine being performed by the rotor velocity (which is the input to the blade angle controller) being estimated in an estimator for the wind turbine. The input to the wind turbine estimator is the estimated incoming wind, so that the tower movements are not visible to the blade angle controller. Negative damping is thus not introduced into the system and the tower oscillations will be expediently damped, while there is also less variation in blade angle, thrust on the rotor and power supplied. | 02-25-2010 |
