Abstract: A method for operating a wind turbine to avoid stall during derating thereof includes providing an initial pitch setting for one or more rotor blades of the wind turbine. Further, the method includes operating the wind turbine based on a rated power curve with the one or more rotor blades fixed at the initial pitch setting. Further, the method includes identifying at least one condition of the wind turbine that is indicative of stall. The method also includes derating the wind turbine. Further, the method includes modifying the initial pitch setting to an updated pitch setting when the at least one condition is identified.

Abstract: A control system for a wind turbine includes a detecting system configured to determine at least one of a rotor load, a wind shear, a wind speed, and a load imbalance due to wind shear. An adjusting system is configured to adjust a shaft moment set point correction value based on at least one of the rotor load, the wind shear, the wind speed, and the load imbalance. A compensating system is configured to compute a shaft moment correction command based on the shaft moment set point correction value output from the adjusting system. A pitch system is configured to adjust a pitch of at least one blade of the wind turbine based on the shaft moment set point correction command, or a yaw system is configured to adjust the yaw position of a rotor based on the shaft moment set point correction command.
