Abstract

This paper is to investigate an excitation scheme for a three-phase SEIG supplies isolated single-phase loads. It will be shown that by arranging the stator winding of the induction generator and appropriate excitation capacitances in the form of the Smith connection, good phase balance in the generator can be achieved, resulting in a high efficiency and large power output. In addition to providing the reactive power for self-excitation, the capacitances also act as phase balancers. Performance analysis is based on the method with the aid of a phasor diagram, the conditions for achieving perfect phase balance are deduced and a method to compute the capacitances required is developed.
