A self-excited induction generator with voltage regulation for use in a remote area power supply

The paper describes a method for calculating the minimum value of self-excitation capacitance necessary to initiate self-excitation with a stand-alone induction generator. Final steady-state self-excitation voltages and frequencies are also evaluated for both loaded and unloaded operation. It is shown that the calculated and measured results are in strong agreement. Final steady-state self-excitation voltages and frequencies are shown to vary with the load demand, in causing poor quality of supply. A new technique is proposed for voltage control to improve the regulation with load.
