IDENTIFYING VOLTAGE AND FREQUENCY REGULATION CURVES OF SELF-EXCITED INDUCTION GENERATOR

A simple method for computation of voltage and frequency regulation curves of a self-excited induction generator is presented in this paper. The method has been successfully exploited for identifying several different types of regulation curves of a 1.5 kW cage rotor self-excited induction generator. The proposed approach is universal and can be used for identification of any generator’s regulation curves, if the parameters of the equivalent circuit are known. Information contained in these computed curves can be very useful while designing systems for automatic control of self-excited induction generators
