摘要： A method of operating a wind turbine includes providing a wind turbine having a plurality of blades. A respective sensor is attached to each of the blades. First measurements of a structural characteristic of each of the blades are repeatedly taken by use of the sensors. A tolerance band is established for the measurements. Signals indicative of the first measurements are wirelessly transmitted only if the first measurements are outside of the tolerance band. The transmitted signals are received at a controller. An actuator signal is sent from the controller to at least one actuator associated with the blades. The sending is in response to the receiving of the transmitted signals. At least one of the blades is actuated dependent upon the actuator signal. The actuating is performed by the at least one actuator. Second measurements of the structural characteristic of each of the blades are repeatedly taken by use of the sensors after the actuating step. The wirelessly transmitting, receiving, sending and actuating steps are repeated for the second measurements.
