To provide a method for properly inspecting a contour of a blade by using a camera mounted on an unmanned aircraft even when the blade of a windmill is rotating due to a strong wind.SOLUTION: A method of inspecting a wind turbine generator system comprises the steps of: periodically determining an angle around a rotation shaft of a blade 11 of a windmill 10 by using inspection data from a distance measurement sensor 22 which is attached to a nacelle 13 of the windmill 10; estimating a rotation angle of the blade 11 after the lapse of a prescribed time from the present time on the basis of a change in the angle around the rotation shaft of the blade 11 up to the present time; determining a flying route for an unmanned aircraft 30 along the blade 11 from the present time to after the lapse of the prescribed time on the basis of the angle around the rotation shaft of the blade 11 at the present time and the estimated rotation angle of the blade 11; and making a camera 33 mounted on the unmanned aircraft 30 image the blade 11 while making the unmanned aircraft 30 fly following the determined flying route.SELECTED DRAWING: Figure 2

    【課題】強風によって風車のブレードが回転している場合にも、無人航空機に搭載したカメラを用いてブレードを適切に外観点検する方法を提供する。【解決手段】風力発電設備の点検方法は、風車10のナセル13に取り付けられた測距センサ22の検出データを利用して、風車10のブレード11の回転軸まわりの角度を定期的に判定するステップと、現時点までのブレード11の回転軸まわりの角度の変化に基づいて、現時点から所定時間後までのブレード11の回転角を推定するステップと、現時点のブレード11の回転軸まわりの角度および推定されたブレード11の回転角に基づいて、現時点から上記所定時間後までのブレード11に沿った無人航空機30の飛行経路を決定するステップと、決定された飛行経路に従って無人航空機30を飛行させながら、無人航空機30に搭載されたカメラ33にブレード11を撮影させるステップとを備える。【選択図】図2
