Abstract: A method for the oscillation damping of a drive train in a wind turbine is proposed. The drive train connects a rotor to a generator. Parameter values representing an oscillation of the drive train are calculated and, on the basis of the calculated parameter values, damping forces which counteract the oscillation of the drive train are exerted in a controlled manner on the drive train by a braking device.

Abstract: A device for filtering lubricants of a wind turbine transmission includes a lubricant inlet and a lubricant outlet. Lubricants of the wind turbine transmission are carried from the lubricant inlet to the lubricant outlet. The device further includes a filter element which is arranged between the lubricant inlet and the lubricant outlet. The filter element is designed such that water is separated from the lubricants by the filter element. A water outlet is connected to the filter element, such that the separated water can be drained out of the device. A hydrocarbon adsorber is arranged between the filter element and the water outlet, such that it purifies the separated water of hydrocarbons.

Abstract: A device for filtering lubricants in a transmission includes a fine filter element which is arranged in a transmission casing and in a lubricant flow in such a way that contaminants of a lubricant are filtered out as a function of a size of the contaminants. The device further includes a magnetic filter element which is arranged spatially separated from the fine filter element. The magnetic filter element is arranged in the transmission casing and in the lubricant flow in such a way that magnetizable contaminants in the lubricant are filtered out with the aid of a magnetic field of the magnetic filter element.
