LUBRICATION SYSTEM FOR A DRIVE TRAIN OF A WIND TURBINE, WIND TURBINE AND METHOD OF LUBRICATING

A lubrication system for a drive train of a wind turbine comprises a main oil tank (201) containing a lubrication liquid, in particular oil, for lubricating the drive train when the wind turbine has connection to a grid and a main reservoir (204) which is separate from the main oil tank (201) and co...

Beschreibung
Zusammenfassung:	A lubrication system for a drive train of a wind turbine comprises a main oil tank (201) containing a lubrication liquid, in particular oil, for lubricating the drive train when the wind turbine has connection to a grid and a main reservoir (204) which is separate from the main oil tank (201) and contains lubrication liquid for the drive train when the wind turbine (10) has no connection to the grid. The main reservoir (204) comprises a first reservoir (214) containing a first amount of lubrication liquid for at least a first component of the drive train and a second reservoir (224) containing a second amount of lubrication liquid for at least a second component of the drive train. The first component is different from the second component. The lubrication system is configured to supply the oil from the main reservoir (204) to the drive train when the wind turbine has no grid connection for creating an oil sump in at least the second component of the drive train (100). Furthermore, a wind turbine comprising such a drive train and a method of lubricating a drive train of a wind turbine are suggested.
