PROJECT TITLE :

Maximum Power Point Tracking Strategy for a New Wind Power System and Its Design Details - 2017

ABSTRACT:

This study presents 2 strategies to enhance the maximum power point tracking strategy for a new wind power system that consists of a planetary gear, 2 permanent magnet synchronous machines, and masses. The generator, the electric motor, and also the wind turbine are connected to the sun gear, ring gear, and carrier of planetary gear, respectively. With the help of an electrical motor, the system can track the most power while not the full-power converter for generator because of its special operating principle. Typical optimum torque (COT) management method with a torque error feed forward branch is proposed to obtain faster response compared with COT control method. Moreover, considering that the actual power cannot reach the theoretical optimum point because of the loss torque of the system, the COT control with torque loss compensation is described. A methodology is additionally proposed to estimate loss torque. Finally, the theoretical analysis is verified by simulation and experiment results.
