An investigation of continuous variable transmission application on wind turbine / Eliz Azima Abd Aziz

The goal of this research is to investigate the possibility of using a continuous variable transmission (CVT) in a wind turbine application. The propose of simulation is to see whether a CVT can be used to let the rotor speed follow the wind speed profile and thus keeping the tip speed ratio, X cons...
