| Outline of Final Research Achievements |
Wind tunnel tests with a scale model which could control 3 blades individually were carried out. Honey comb plates were installed to create the wind speed shift according to the altitude. A forced oscillation machine was also installed at the base of the tower to imitate the floaters pitching motion in waves and wind. Wake from the upstream wind turbine model was measured and wake effect on another wind turbine model which was installed behind the upstream wind turbine model was also obtained. The individual blade pitch control developed in this research work was applied to the upstream wind turbine model and the control algorithm was effective from the viewpoint of the reduction of the fluctuation of rotor speed in the downstream wind turbine model. Numerical simulation was carried out and the results were compared with the results of the wind tunnel tests.
