Wind turbine output characteristics and output power

① Output characteristics of wind turbineThe torque produced by a horizontal-axis wind wheel with a fixed pitch varies with wind speed and rotation speed. If the rotation speed of the blade is too low, the blade will stall and the torque output by the wind wheel will decrease. Therefore, in order to obtain the maximum […]
