A method of calibrating one or more load sensors of a blade of a wind turbine, said wind turbine comprising a main generator, a power electronic converter connected with the main generator, and a rotor operationally connected with the main generator and carrying the blade. The method comprises acting on the power electronic converter to operate the main generator as motor to set the blade in at least one predetermined condition. The method further comprises measuring loads in the predetermined condition using the load sensors of the blade and calibrating the blade load sensors taking into account the measured loads. |
