Patent number: 11603822Abstract: A method of erecting a wind turbine on a wind turbine site, the wind turbine comprising a turbine tower and a nacelle. The method comprises the following steps: providing a plurality of tower sections being arrangeable upon each other in a vertical orientation in a tower structure to form the turbine tower; providing at least one damper unit configured to dampen oscillations of the turbine tower; attaching a damper unit to one of the plurality of the tower sections on an outside thereof, and subsequently arranging the tower section in the tower structure, and arranging the nacelle on top of the tower structure while the damper unit is attached to a tower section in the tower structure.Type: GrantFiled: April 27, 2022Date of Patent: March 14, 2023Assignee: Vestas Wind Systems A/SInventors: Rasmus Sanderhoff Johansen, Søren Bøgelund Madsen, Jes Grøn Andersen, Jakob Anders Sørensen

Patent number: 11560878Abstract: The present invention relates to a damper unit for damping oscillations of a tower structure when secured thereto, the damper unit comprising a damper unit structure adapted for attachment to the tower structure, a pendulum structure, a suspension arrangement for suspending the pendulum structure from the damper unit structure such that the pendulum structure is allowed to displace from a neutral position for the pendulum structure, the suspension arrangement comprising one or more wires for suspending the pendulum structure, a sensor adapted for measuring oscillations of the tower structure, and tuning means configured for adjusting the natural frequency of the suspended pendulum structure in response to measured oscillations of the tower structure. The present invention further relates to an associated method.Type: GrantFiled: June 26, 2019Date of Patent: January 24, 2023Assignee: Vestas Wind Systems A/SInventors: Søren Bøgelund Madsen, Jes Grøn Andersen
