Three-phase self-excited induction generator analysis in stand-alone mode

Currently, to supply power for a modern life, many researchs are being directed at alternative energy sources. One of the most promising sources is wind energy. In isolated systems, squirrel cage induction generators with capacitor excitation, known as self-excited induction generators (SEIG), are very popular. This paper presents a steady state analysis of three-phase self-excited induction generator with parallel compensation. An arrangement using a variable speed drive and a 4.4 KW induction machine excited with a capacitor bank to supply resistive or resistive-inductive loads was the subject of investigation. A new method, for determining the minimum and maximum capacities ensuring the performance of self-excited induction generator by a simple mathematical model, is presented.
