The present invention relates to a tower damper adapted to be mounted in a wind turbine tower, the tower damper comprising a pendulum structure adapted to be suspended in the wind turbine tower; a plurality of springs arranged to dampen movements of the pendulum structure; a suspension arrangement for suspending the pendulum structure; and a chamber holding a damping liquid into which damping liquid the pendulum structure is at least partly immersed. The present invention further relates to a wind turbine comprising a tower damper.

Tower vibration damper

The present invention relates to a wind turbine tower comprising a tower vibration damper () with a tuned mass damper and one or more impact damping units (). The tuned mass damper comprises a pendulum structure (), a chamber connecting a friction media () to the pendulum structure () is at least partly immersed, and a suspension arrangement (-) suspending the pendulum structure () inside the wind turbine tower such that the pendulum structure () is allowed to displace from a neutral position towards the outer boundary () of the chamber. The impact damping units () are positioned between the pendulum structure () and the outer boundary (), such that the outer boundary () of the chamber and the pendulum structure () may collide via the impact damping units ().
