Increasing Efficiency of Wind Turbine by the Use of Sweep Twist Adaptive Rotor
نویسنده
چکیده
-Renewable energy has become the prime source of clean and pure form of energy. With the prevailing energy crisis non-conventional energy has become the solution to it. Harnessing wind energy by several wind turbines is commonly done using various types of rotors. But nowadays Seep twist adaptive rotor blades are used to increase annual energy capture of baseline turbine by 5%-10% without exceeding baseline rotor loads. To achieve this rotor radius was increased from 24 m to 27 m.
