Abstract
Method for operating a wind turbine comprising a drive train driving one or more electrical generators that supply power to an electric grid, by which, in events that can create a load inversion in the gearbox, a drive train dump load is activated for ensuring that the drive train torque has a constant direction, avoiding the impact of backlashes in the gearbox, the dump load including of power absorbed by one or several systems specifically dedicated to the absorption of the dump load and present at the wind turbine for other purposes.
Claims12
Method for operating a wind turbine comprising a drive train driving one or more electrical generators (23, 31) that supply power to an electric grid (11), the drive train including a rotor hub (13), to which one or more blades are attached, a main shaft (15), a gearbox (17) and connecting shafts (19) to said one or more electrical generators (23, 31), characterized in that, in events that can create a load inversion in the gearbox (17), a drive train dump load (5) is activated for ensuring that the drive train torque has a constant direction, avoiding the impact of backlashes in the gearbox (17), said dump load (5) consisting of power absorbed by one or several means chosen among means specifically dedicated to the absorption of said dump load (5) and means present at the wind turbine for other purposes.
