System and method for reducing loads acting on a wind turbine in response to transient wind conditions by means of pitch control

摘要

A method 200 for reducing loads acting on a wind turbine 10 in response to transient wind conditions is disclosed. The method 200 may generally include determining 202 an actual value for a blade parameter of a rotor blade of the wind turbine using a first sensor associated with the rotor blade, monitoring 204 a secondary operating parameter of the wind turbine using a second sensor, determining 206 a predicted value for the blade parameter based on the secondary operating parameter, comparing 208 the actual value to the predicted value and performing 210 a corrective action to reduce the loads acting on the wind turbine 10 if the actual value differs from the predicted value by at least a differential threshold.
