Energy generated from natural resources, such as sunlight and wind, is desirable due to the environmental-friendly factor associated therewith. For example, wind turbines are known for converting rotational movement of the turbine blades, caused by the wind, into electricity. Specifically, the rotation of turbine blades is utilized for the rotation of a shaft, connected to a generator, for producing electricity.
To achieve an optimum output of a wind turbine, the rotation of the turbine blades need to be regulated with varying wind speeds/conditions. Specifically, the turbine blades should be allowed to rotate at a set rated revolution per minute (rpm) for achieving the optimum output. However, to maintain the set rated rpm of the turbine blades may be difficult during sudden rise in wind speed or storm. Specifically, rise in wind speed may cause over speeding of the turbine blades, which may cause damage to the wind turbine. Further, fixing such damages may become expensive and time consuming affair.
