Maximum power tracking of wind power generation system with inverter excited induction machine

This paper shows a new induction generation system for wind power generation. This system has the voltage source converter exciting induction generator and the PFC converter to transfer the real power. This configuration enables asynchronous link and maximum power tracking for the cage rotor induction generator. Usually two full rating inverter sets are necessary to construct the asynchronous link. Proposed system uses an inverter of small rating, 10% of full rating, and a PFC converter can replace the roll of the real power transfer at the generator side. This configuration can reduce the total system costs. This paper has investigated the maximum power point tracking control of the proposed system by simulation. The simulation results show the good tracking ability and certify the reduction of the inverter rating at the generator side.
