Abstract
The present invention relates to an aerodynamic speed control system (shown in fig 1) for controlling the speed of the wind turbine spontaneously. The system achieves speed control by means of mechanical and electronic configurations. The mechanical configuration controls the turbine speed by enabling aerodynamic braking with respect to centrifugal force however without additional power supply. The electronic configuration is act as a backup system to perform the task of centrifugal force and also control the speed of the turbine in different conditions like grid failure, stopping of turbine at required condition and unavailability of power. Further the electronic configuration is controlled by a control means with respect to sensing means (shown in fig 4a&4b) which can sense the turbine speed as well as pitching angle.
