A novel simplified approach for evaluation of performance characteristics of SEIG

This paper presents a simple method of evaluating the performance characteristics of a Self Excited Induction Generator (SEIG) using Scilab. Scilab is a free and open source software for numerical computation and is used for engineering and scientific applications. This paper incorporates a numerical-based routine available in scilab that avoids the detailed algebraic derivations required for performance evaluation. Mathematical models for evaluating the steady state behaviour of SEIG under no-load, variable load and constant machine terminal voltage operation are developed. The developed model is then used to predict the performance of a 3.7 kW, 415 V, 7.6 A, 1430rpm induction machine available in the laboratory. The results validate theoretical studies.
