Steady-state analysis of self-excited induction generators

Abstract

Two solution techniques for the steady-state analysis of a self-excited induction generator (SEIG) are presented in this paper. The first technique employs a novel parameter elimination procedure to yield a 7th-degree polynomial in the per-unit frequency, numerical solution of which enables the performance of the SEIG to be determined. The second technique employs symbolic programming for the derivation and solution of the the high-order polynomial. The symbolic programming technique is further extended to the analysis of a voltage compensated SEIG using long-shunt connection. Very good agreement between experimental and computed results have been obtained on a 2 kW laboratory machine.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
