摘要： The present disclosure is directed to a system and method for mitigating ice throw from one or more rotor blades of a wind turbine during operation. The method includes monitoring one or more ice-related parameters of the wind turbine. Thus, the ice-related parameters are indicative of ice accumulation on one or more of the rotor blades. In response to detecting ice accumulation, the method also includes implementing an ice protection control strategy. More specifically, the ice protection control strategy includes determining a yaw position of the wind turbine and determining at least one of a power set point or a speed set point for the wind turbine based on the yaw position.

摘要： The present subject matter is directed to a system and method for operating a wind turbine so as to increase power production by utilizing variable tip-speed-ratio control. In one embodiment, the method includes defining a first operating region associated with an unsaturated torque range and a second operating region associated with a saturated torque range. Further, the method includes monitoring a torque output of the wind turbine. The method also includes continuously adjusting a tip-speed-ratio set point of the wind turbine so as to operate the wind turbine along a torque constraint boundary of the first and second operating regions.

摘要： The present subject matter is directed to a system and method for dynamically controlling a wind turbine. The method includes operating the wind turbine based on a thrust set point and a speed set point. A next step includes determining a desired change in actual speed of the wind turbine in response to control actuations starting from an instantaneous operating point. The method also includes determining a desired change in thrust of the wind turbine in response to control actuations starting from the instantaneous operating point. Next, the method determines at least one parameter set point that achieves the desired change in speed and the desired change in thrust and controls the wind turbine based on the parameter set point so as to maintain the actual thrust and the actual speed of the wind turbine within a certain tolerance of the thrust set point and the speed set point, thereby regulating loads acting on the wind turbine while simultaneously maintaining optimal or near optimal power output.

摘要： A method for optimizing power production of a wind turbine includes determining at least one operational constraint for the wind turbine. The method also includes operating the wind turbine with at least one operational constraint being activated. Further, the method includes varying a tip speed ratio for the wind turbine while the at least one operational constraint is activated so as to maximize a power coefficient of the wind turbine.
