Performance evaluation of single phase self excited wind generator using three phase machine

This paper presents performance evaluation of an improved low cost single phase self excited induction generator (SEIG) using a three phase machine. This machine can be used in grid isolated and remote areas as a portable source of power supply. The reactive power requirement for this type of generator is provided through a single capacitor of suitable value and a single phase inverter with a photovoltaic (PV) module which acts as a dc bus to the inverter. The inverter along with the PV module acts as a variable source of excitation during the variable load and wind speeds which aid in providing stable load voltage with fixed frequency. Performance of such a generation scheme is analyzed using suitable simulations and experiments. The scheme shows encouraging results and thus also validates the proposed strategy.
