A flexible coupling for use in a wind turbine power transmission system to flexibly couple terminal portions of the wind turbine power transmission system to thereby accommodate misalignments in a radial and axial direction between the terminal portions. A coupling element of the flexible coupling interfaces with the terminal portions associated with a main shaft and a gearbox input member of the wind turbine power transmission system. Thereby a double-joint, namely two joints between the coupling element and the respective terminal portions, is defined. The joints permit relative rotation between the coupling element and the respective terminal portion around axes perpendicular to and relative translation along a main axis of the main shaft. Thereby the two joints can provide translational degrees of freedom in all directions and rotational degrees of freedom only about axes perpendicular to the main axis to accommodate radial, axial, and angular misalignments. A torsionally stiff coupling element may constrain relative rotation about the main axis.

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. Further, the method includes implementing, via a controller, the control scheme for the auxiliary lubrication system to provide the lubrication to the gearbox of the wind turbine during the off-grid state.
