| Outline of Final Research Achievements |
In this study, strain gauges were installed inside the blades and nacelle of a large commercial wind turbine. Based on these measurement data, we conducted an empirical study to clarify the correlation between "topographic turbulence" and "rotational turbulence" and "wind turbine vibration (wind turbine fatigue load)." At the same time, we also reproduced in detail the topographical data around the wind turbine targeted in this study. Using these data, we also conducted numerical wind condition simulations using CFD. In addition to visualizing the complex three-dimensional airflow structure, we attempted to develop evaluation indicators regarding the effects of turbulence on the wind turbine blades and internal components of the nacelle.

| Academic Significance and Societal Importance of the Research Achievements |
本研究開発で得られた種々の知見を複雑な山間部に風車を建設する際，さらには風車建設後の維持・管理(メンテナンスシステム)に効率的に反映されれば，風車の重大故障を未然に防ぎ，かつ風車あるいはウィンドファームの最適な運用に繋がることは確実である．
さらに本研究で得られた一連の知見は，現在注目を集めている大型洋上風力発電へも即座に適用可能である．具体的には，複数の風車の設置間隔などを適切に決定する際に非常に有用となる．また，上記の陸上風力と同様，建設後の維持・管理にも適用可能である．
