System and method for controlling the operation of a wind turbine

A method for controlling the operation of a wind turbine, the method comprising:

• monitoring, with a computing device, a current yaw position of a nacelle of the wind turbine, the current yaw position being located within one of a plurality of yaw sectors defined around a range of travel for the nacelle;
• monitoring, with the computing device, a generator speed of the wind turbine;
• monitoring, with the computing device, a wind speed associated with the wind turbine;
• determining, with the computing device, a standard deviation of the generator speed over time, wherein the variance is indicative of variations in the wind speed;
• determining, with the computing device, at least one curtailed operating setpoint for the wind turbine when the variance exceeds a predetermined variance threshold and when the wind speed exceeds a predetermined wind speed threshold, wherein the at least one curtailed operating setpoint is determined based at least in part on historical wind data for the yaw sector associated with the current yaw position;
• and
• operating the wind turbine based on the at least one curtailed operating setpoint.

A system for controlling the operation of a wind turbine, the system comprising:

• a computing device including a processor and associated memory, the memory storing instructions that, when implemented by the processor, configure the computing device to:
• monitor a current yaw position of a nacelle of the wind turbine, the current yaw position being located within one of a plurality of yaw sectors defined around a range of travel for the nacelle;
• monitor a wind-dependent parameter of the wind turbine;
• determine a variance of the wind-dependent parameter over time, wherein the variance is indicative of variations in a wind parameter associated with the wind turbine;
• and
• determine at least one curtailed operating setpoint for the wind turbine when the variance exceeds a predetermined variance threshold,
• wherein the at least one curtailed operating setpoint is determined based at least in part on historical wind data for the yaw sector associated with the current yaw position.
