Abstract

Blade loads acting on a rotor blade are usually determined taking into account strains acting thereon, which can be detected by strain sensors. To date, strain sensors have been adjusted using a rotor angle. Detection of the rotor angle is, however, often unreliable or inaccurate, and therefore no adequate solution has been found to date for adjusting the strain sensors simply and accurately. According to the invention, the problem is solved by a computer-implemented method for adjusting a first blade load measurement system having at least one strain sensor on a first rotor blade of a wind turbine, the method comprising the following steps: a first acceleration is measured by means of a first acceleration sensor; a first reference bending moment and/or a first reference axial force is/are determined based on the first acceleration measured; a first measured bending moment and/or a first measured axial force is/are determined based on values measured by the at least one strain sensor of the first blade load measurement system and a first adjustment parameter set, containing first initial adjustment parameter values, assigned to the first blade load measurement system; a first deviation of the first reference bending moment and/or the first reference axial force from the first measured bending moment and/or the first measured axial force is determined; the adjustment parameter values of the first adjustment parameter set for the first blade load measurement system are adapted such that the first deviation is less than or equal to a threshold value.
