摘要
A method of determining fatigue load of at least one operative wind turbine, comprising the steps of: - providing (110) a transfer function that associates an obtained at least one measurement value of a first sensor to an obtained at least one measurement value of a second sensor the at least one measurement value of the first sensor and the at least one measurement value of the second sensor being obtained by use of a reference wind turbine at which the first sensor and the second sensor are located - obtaining (120) at least one measurement value of a third sensor, wherein the third sensor is located at the at least one operative wind turbine, and wherein the third sensor corresponds in type and position to the first sensor at the reference wind turbine; - Calculating (130) at least one transfer function value corresponding to the obtained at least one measurement value of the third sensor by use of the provided transfer function; - Calculating (160) the fatigue load of the at least one operative wind turbine based on the calculated transfer function value.
