Squirrel-cage induction machine is widely used as workhorse motor in industrial due to its simple and rugged construction. Special application such in micro-hydro power generation employs squirrel-cage induction machine as generator in self-excited operation called Self-Excited Induction Generator (SEIG). Often micro-hydro power generation in remote area operates as single phase supply since simple loads e.g. lighting, TV set and other household appliances are used. Single phase operation of three phase machine causes derating on the machine capacity due to stator current unbalance. This paper shows optimal sizing of excitation capacitor for three phase SEIG operated in single phase load. Sizing is aimed to maximize generator capacity by considering stator winding current capability and voltage across windings. Size of excitation capacitor is optimized using particle swarm optimization (PSO). Results are verified through simulation and experimental on a three phase squirrel cage induction machine of 0.75 kW, 380 V. Simulation and experimental results show that optimization is able to increase power transfer capability of SEIG from 33.33% to 44.35% of rated machine. Simulation and experimental results are shown in Figures below.
