    INSPECTION METHOD FOR WIND TURBINE GENERATOR FACILITY

    INSPECTION METHOD FOR WIND TURBINE GENERATOR FACILITY

    Freier Zugriff

    To inspect wind turbine generator facilities at a long distance, for example, on the sea with an unmanned aircraft which autonomously flies.SOLUTION: An inspection method for wind turbine generator facilities comprises the steps of: allowing an unmanned aircraft 10 to autonomously fly to over a wind turbine 40; determining, by the unmanned aircraft 10, the current azimuth of a nacelle 43 over the wind turbine 40; allowing the unmanned aircraft 10 to move to a position where the unmanned aircraft faces a hub 42 based upon the determined current azimuth of the nacelle 43; allowing the unmanned aircraft 10 to determine a current angle of rotation of a first blade 41A at the position where the unmanned aircraft faces the hub 42; allowing the unmanned aircraft 10 to move to an inspection start position of the first blade 41A based upon the determined current angle of rotation of the first blade 41A; and photographing, by a mounted camera, an inspection image of the first blade 41A while the unmanned aircraft 10 moves from the inspection start position along a lengthwise direction of the first blade 41A.SELECTED DRAWING: Figure 3

    【課題】洋上など遠距離にある風力発電設備を、自律飛行する無人航空機によって点検する。【解決手段】風力発電設備の点検方法は、無人航空機１０が風車４０の上空まで自律飛行するステップと、無人航空機１０が風車４０の上空においてナセル４３の現時点の方位を判定するステップと、判定したナセル４３の現時点の方位に基づいて、無人航空機１０がハブ４２に正対する位置に移動するステップと、無人航空機１０がハブ４２に正対する位置において第１ブレード４１Ａの現時点の回転角度を判定するステップと、判定した第１ブレード４１Ａの現時点の回転角度に基づいて、無人航空機１０が第１ブレード４１Ａの点検開始位置に移動するステップと、無人航空機１０が点検開始位置から第１ブレード４１Ａの長手方向に沿って移動しながら、搭載されたカメラによって第１ブレード４１Ａの点検用画像を撮影するステップとを備える。【選択図】図３
