Abstract

A method (100) for protecting a wind turbine (10) from an extreme change in wind direction includes receiving a wind direction and/or a wind speed at the wind turbine (10). When a change in the wind direction or the wind speed exceeds a predetermined threshold, the method (100) includes determining a margin to stall and/or zero lift of the at least one rotor blade (22) of the wind turbine (10) as a function of an angle of attack or change in the angle of attack at a blade span location of at least one rotor blade (22) of the wind turbine (10). The method (100) also includes implementing a corrective action for the wind turbine (10) (without shutting down the wind turbine (10)) when the margin to stall and/or zero lift exceeds a predetermined value so as to avoid stall and/or negative lift on the at least one rotor blade during operation of the wind turbine (10).
