Abstract
A method calibrates a load sensor in a rotor blade of a wind turbine. The method includes checking a state and/or operating parameters of the wind turbine; continuously measuring a calibration condition for the wind turbine and comparing the measured calibration condition with predefined calibration prerequisites; switching to a calibration mode when the measured calibration condition meets the predefined calibration prerequisites or switching to a restricted production mode when the measured calibration condition does not meet the predefined calibration prerequisites; and, collecting measurement data in the calibration mode. The calibration mode is terminated when the required data have been collected for the calibration; and, switched from the calibration mode to an interruption mode. The mode is switched from the interruption mode to the restricted production mode when the measured calibration condition does not meet the predefined calibration prerequisites for longer than a predefined period of time.
