In the paper, sudden short-circuit transients at terminals of an autonomous single-phase induction generator were simulated using field-circuit 2D model of the single-phase induction generator. The transients at terminals were calculated for different configurations of capacitors in stator windings. Some experimental results showing re-excitation of the stator voltage after sudden short-circuit at terminals under no-load operation of the generator were also presented for the generator with only a capacitor connected to excitation stator winding.
