Outline of Final Research Achievements

In the present study, an aero-elastic-control coupled simulation model for a vertical axis wind turbine-generator system was developed to with the analysis of a floating offshore wind power generation system using a counter-rotating vertical axis-type wind turbine in mind. As the first phase of our study, the coupled behavior of a land-based straight-wing-type vertical axis wind turbine-generator system under turbulent wind variations was analyzed to obtain basic knowledge for a counter-rotating vertical axis-type wind turbine. The numerical analysis revealed that the variations in the turbine torque with the frequency corresponding to three times as much as the rotation frequency greatly influence the elastic vibration and load variations at high wind speeds.
