Micro Hydro Power Plant with Induction Generator Supplying Single Phase Loads

Abstract

This paper presents a new method to supply single-phase loads using a three-phase induction generator (IG). The voltage and frequency regulation, as well as the phase IG phase balancing, is ensured by a combination between a voltage source inverter (VSI) and a dump load (DL). Operating at a constant frequency, the VSI keeps the system frequency also constant and deals with unbalanced compensation, while the DL performs the voltage regulation. Through simulations and experiments, the reliability of such a configuration is tested.
