METHODS AND SYSTEMS FOR CONTROLLING A WIND TURBINE

A method 200 for controlling a wind turbine includes receiving 202 signals representative of oncoming wind speeds approaching at least a portion of a wind turbine, receiving 204 background noise and signals representative of signal-to-noise ratios corresponding to the signals representative of the oncoming wind speeds, determining 208 an availability-and-atmospheric noise in the signals based on one or more of the signal-to-noise ratios, blade positions of blades of the wind turbine, and the yaw position of a nacelle of the wind turbine, determining 210 a wind incoherence noise in the signals due to a change in the oncoming wind speeds while approaching at least the portion of the wind turbine, determining 212 a net measurement noise in the signals based on the background noise, the availability-and-atmospheric noise, and the wind incoherence noise, and controlling 214 the wind turbine based at least on the signals representative of the oncoming wind speeds and the net measurement noise.
