Active filter action using DFT to reduce peak exciting current of new induction generator system for wind power generation

This paper shows new induction generation system for wind power generation. This system has inverter excited induction generator and the PFC converter to transfer the real power. Simulation and experimental results certifies that the dc/dc chopper control of the PFC converter can minimize the inverter current, which only supplies exciting current for the induction generator. It is also shown that the harmonic components of the current from the inverter are suppressed by the active filter action in the output voltage control of the inverter.
