| Research Abstract |
In this study, we research and develop of overspeed prevention control mechanism operable strong wind region specialized type wind power generation system at any strong wind range (wind speed 15m/s-25m/s). Here, we developed a "double pitch control mechanism of the wind turbine" air brake system for preventing over-rotation of the horizontal axis wind turbine, and subjected to running test were made that demonstrated machine (3kw). It was confirmed by field tests that by inducing a stall and recovering such a phenomenon, excessive rotation of the wind turbine can be prevented, and analyzed aerodynamic-kinetic mechanism. Furthermore, dynamic systems theory and blade element theory, analyzes the stall control behavior, while washing out the disadvantages of the control mechanism, and designed a new control method, we show the effectiveness of the numerical simulation.
