Abstract

A method of calibrating a load measurement apparatus for measuring a load on a wind turbine blade (2) on the basis of strain data based on a strain of the wind turbine blade includes: a strain-data acquisition step of, during a startup of a wind turbine (1), obtaining a plurality of the strain data for each of a plurality of conditions in which at least one of an azimuth angle or a pitch angle of the wind turbine blade varies; a theoretical load-value acquisition step of obtaining a theoretical load value applied to the wind turbine blade due to the own weight of the wind turbine blade, for each of the plurality of conditions, on the basis of the azimuth angle and the pitch angle of the wind turbine blade in each of the plurality of conditions; and a calibration-parameter calculation step of calculating a calibration parameter representing a relationship between the strain data obtained by the load measurement apparatus and the load on the wind turbine blade, on the basis of a correlation between each of the strain data and the theoretical load value.
