摘要
A method for state monitoring of a rotor blade of a wind turbine is described. The method comprises: measuring an acceleration of the rotor blade with a first signal, wherein the acceleration is measured at a first position at a predetermined distance from the rotor blade root in at least one direction comprising a first directional component orthogonal to the axis of the rotor blade, measuring a strain of the rotor blade with a second signal, wherein the strain is measured at a second position disposed in the area of the first position to the rotor blade root, determining a first positional change at the first position on the basis of the acceleration, determining a first value corresponding to the rotor blade stiffness or to the rotor blade elasticity by means of calculation on the basis of the first positional change and the strain, and determining the rotor blade state from the first value.
