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.

Abrégé

The invention relates to a system for protecting a leading edge on a wind turbine rotor blade, a vacuum sheet for use in the system and a method for, in situ, protecting a part of a leading edge of a wind turbine rotor blade. The system comprises a protective cover sheet to be arranged on a part of a leading edge of a wind turbine rotor blade. The protective cover sheet has a pressure-sensitive adhesive material for adhesively bonding the protective coversheet to the part of the rotor blade. The system further comprises a vacuum sheet having a textured bottom surface and a sealing element arranged at a peripheral circumference and suitable for being connected to a vacuum pump and for being arranged to the protective cover sheet in a full covering and overlapping manner where the sealing element engages the surface of the rotor blade. The protective cover sheet is hereby arranged in a sealed chamber between the rotor blade and the vacuum sheet, and the vacuum system creates a vacuum inside the sealed chamber which forces the textured bottom surface against the protective cover sheet, which activated the pressure-sensitive adhesive material.
