Abstract
A lubrication system for a drive train of a wind turbine includes an oil reservoir having an outlet, a supply valve, a gearbox having an oil inlet and oil outlet, a drain valve and a siphon is provided. The oil reservoir is coupled to the supply valve and the supply valve is coupled to the inlet of the gearbox. The oil outlet of the gearbox is coupled to the drain valve and to a first end of the siphon. The supply valve is configured to open in an off-grid state of the wind turbine and the drain valve is configured to close in the off-grid state of the wind turbine. The siphon is configured to adjust an internal oil level in the gearbox in the off-grid state of the wind turbine.
