SYSTEM AND METHOD FOR REDUCING LOADS ACTING ON A WIND TURBINE IN RESPONSE TO TRANSIENT WIND CONDITIONS

摘要

A method for reducing loads acting on a wind turbine in response to transient wind conditions is disclosed. The method may generally include determining 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 a secondary operating parameter of the wind turbine using a second sensor, determining a predicted value for the blade parameter based on the secondary operating parameter, comparing the actual value to the predicted value and performing a corrective action to reduce the loads acting on the wind turbine if the actual value differs from the predicted value by at least a differential threshold.

1. A method for reducing loads acting on a wind turbine in response to transient wind conditions, the method comprising:
determining 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 a secondary operating parameter of the wind turbine using a second sensor, the secondary operating parameter differing from the blade parameter; determining a predicted value for the blade parameter based on the secondary operating parameter; comparing the actual value to the predicted value; and performing a corrective action to reduce the loads acting on the wind turbine if the actual value differs from the predicted value by at least a differential threshold.
