| Outline of Final Research Achievements |
The application of the small-scaled wind power generation system is very wide. However, its diffusion has not progressed. The reason for this is caused by frequent breakage accidents caused by excessive rotation of blades caused by strong winds. In other words, driving a small-scaled wind power generation system in a strong wind induces over-speed and causes a phenomenon that the blade is destroyed. In this research, in order to prevent over-rotation of the small wind turbine, we developed an adaptive stall mechanism that brakes non-contactly the rotation of the wind turbine rotation shaft by electromagnetic force using the generator output current, and passive Pitch pitch angle stall control method. We evaluated both control systems and developed an output stabilization system that suppresses the output fluctuation of the wind power generation system as much as possible.
