Abstract :
This paper proposes a method to reach the maximum power point of a Magnus wind turbine. Firstly, a special discussion is made about this turbine and its behavior showing that this turbine is a special case of the horizontal axis wind generator, using rotating cylinders instead of fixed blades. Secondly, it is presented an explanation of how some maximum power point trackers (MPPT) can be used with wind energy conversion system and, specially, the divided step hill climbing search method (HCS). The MPPT method proposed for the Magnus turbine is based on the control of cylinder rotation speed to change the tip speed ratio. Finally, simulation results are presented with the proposed MPPT method applied to a Magnus wind turbine.
