Abstract

This paper shows new induction generation system for wind power generation. This system has the voltage source converter (VSC) exciting induction generator (IG) and the power factor correction (PFC) converter to absorb the real power in parallel. Rating of the VSC is minimized since it supplies reactive power only and the PFC converter absorbs all the real power. The cost of IG is much lower than synchronous generator with permanent magnets (PMSG) and is possible to have the maximum power point tracking (MPPT) control by using VSC for exci tation. We also propose to minimize the loss in IG to increase the efficiency or the reactive power consumption of IG to decrease the rating of the VSC. The effectiveness of the proposed control for the wind power generation system was verified by simulation and experiments.
