Efficiency improvement on wind turbine through bump up stepper motor

This paper presents with the starting torque provision for the wind turbines which are sometimes not rotating even at cut-in wind speed, (rotation sensed through output power of the turbine) here if the power is zero above the cut-in wind speed then the turbine is not in running condition. Here we are using the sensorless sensing method, by providing some extra torque through stepper motor for starting purpose we will improve the efficiency of the wind turbines. Normally the speed of the wind is not a constant, hence by providing this type of set-up can make the wind turbine to rotate to its maximum extent (i.e. the rotation time increases,efficiency improves). Also the supply for the stepper motor proposed to be provided with solar panels to make the system more eco-friendly and self-supporting.
