Abstract
A method for detecting and responding to damage in a rotor blade of a wind turbine includes monitoring at least one signal of a pitch actuator of a pitch system of the rotor blade of the wind turbine. The signal(s) is a proxy for a pitch driving torque of the pitch actuator of the pitch system. Thus, the method includes defining a metric that captures certain behavior of the proxy for the pitch driving torque of the pitch actuator of the pitch system. The method further includes comparing the metric to a corresponding metric associated with a reference rotor blade representing a healthy rotor blade. Moreover, the method includes implementing a control action when the metric is outside of a predetermined range defined by the healthy rotor blade.
