  • Method for adjusting unevenness of top flange of wind turbine generator tower
    Patent number: 8240044
    Abstract: The unevenness of the upper surface of a top flange of a wind turbine generator tower is adjusted by arranging shim plates on the upper surface of the top flange and by adjusting the thicknesses and/or number of the shim plates to be disposed at individual positions. First, the roughness levels of the upper surface of the top flange are measured at a plurality of measuring points in a state in which a nacelle of the wind turbine generator is not mounted on the tower, which is vertically erected. Next, the thicknesses and/or number of the shim plates to be disposed on the individual plurality of measuring points to adjust the unevenness of the upper surface of the top flange are determined in accordance with the measured roughness levels of the upper surface of the top flange.
