Calibration method
First Claim
1. Method for the operation of a wind power plant that includes a method for the calibration of at least one sensor, wherein the wind power plant has at least one movable component, comprising the steps of:
- pivoting or rotating the movable component on a predeterminable axis andevaluating a measurement value captured by the at least one sensor, which is a measure for the load of the movable component,wherein the calibration method is performed automatically and the calibration method is initiated by a calibration signal,stopping the wind power plant after the initiation of the calibration method by the calibration signal or performing the calibration method during trundling of the wind power plant,wherein the evaluation step includes that in the case of a deviation of the captured measurement value, adjusted by a calibration function, from a specifiable and/or saved and/or determined reference, which is greater than a specificable deviation setpoint value, the measurement value adjusted by the calibration function is the basis for the creation and saving of an adjusted calibration function, andwherein the evaluation step includes that in the case of a deviation of the captured measurement value from a specifiable and/or saved and/or determined reference, which is greater than a specifiable deviation threshold value, the captured measurement value is the basis for the creation and saving of the adjusted calibration function.

Abstract
The invention relates to a method for the calibration of at least one sensor (11-14) of a wind power plant (10). The invention also relates to a wind power plant (10). The calibration process according to the invention is captured by the at least one sensor (11-14). The measurement value (30, 31), which is a measure for the load of a component (15-17), is evaluated, wherein the wind power plant has at least the moveable component (15, 15′, 15″, 16, 17), wherein the component (15-17) is pivoted or rotated around a predeterminable axis (19, 20). The wind power plant according to the invention is provided with a calibration module for the automatic calibration of at least one sensor (11-14), which measures the load of a movable component (15-17) of the wind power plant.
