Abstract :
Frequency and voltage control of a stand-alone induction generator along with a voltage source inverter (VSI) controller to supply the reactive power required for excitation of induction generator is proposed. The VSI-based controller also regulates the generated voltage and frequency by maintaining a constant impedance as observed by the generator. This provides sufficient time to regulate the prime mover. A system model is developed and an experimental setup is built. Results indicate a wide control range and elimination of the three-phase AC capacitor bank. Sever load changes up to 100% are tested with no noticeable change on the voltage or frequency
