Abstract (en)
[origin: WO2014040598A1] A method of damping oscillations in a wind turbine tower comprises connecting a bag of material or liquid to a tower component at a first lateral distance away from a tower wall. The bag is also suspended from the tower component by a first vertical distance. The height of the tower component is known such that the first vertical distance corresponds to a particular height within the tower. The first lateral distance, first vertical distance, and mass of the bag are such that the bag is configured to act as a pendulum counteracting a fundamental mode of vibration of the tower.
