TUNED LIQUID DAMPER OF A WIND TURBINE

摘要

A liquid damper in a wind turbine is provided. A damper system of a direct driven wind turbine is disclosed, whereby the wind turbine comprises a nacelle, a rotor hub and an electric generator. The electric generator comprises a rotor and a non-rotating part. The rotor hub is connected to the rotor of the electric generator. The non-rotating part of the generator is connected to the nacelle. The wind turbine comprises a damper system to at least partially eliminate an unwanted movement of the wind turbine resulting from wind loads, whereby the damper system comprises a liquid damper. The damper system is arranged at a non-rotating part of the electric generator.
