Abstract: A method for providing gearbox lubrication of a wind turbine during an off-grid state includes fluidly coupling an auxiliary lubrication system with a gearbox of the wind turbine. The off-grid state is characterized in that the wind turbine is mechanically and electrically installed at a wind farm but not yet connected to a grid. The method also includes determining a time-based control scheme for the auxiliary lubrication system to provide lubrication to the auxiliary lubrication system during the off-grid state. The time-based control scheme is defined a first time period in which the lubrication is provided to the gearbox via the auxiliary lubrication system during the off-grid state and a second time period in which the lubrication is not provided to the gearbox via the auxiliary lubrication system during the off-grid state. The first time period is less than the second time period.
