Outline of Final Research Achievements

The present study researches the output fluctuation of horizontal axis wind turbines due to the variation of inflow wind velocity, and aims at decreasing the fluctuation amplitude by controlling their rotor speed and/or their blade pitch. In order to achieve the target we have conducted the following researches.
1. We have constructed a numerical analysis model which can simulate the behavior of the wind turbine running in the natural wind, and confirmed its validity by comparing the calculated results with the measurements.
2. We have constructed an estimation scheme of instantaneous wind velocity flowing into the turbine rotor, and developed an control procedure which can reduce the fluctuation amplitude of the turbine output.
