Performance Analysis of a Wind Turbine Based on a Self-Excited Induction Generator (SEIG)

In this paper, magnetic saturation effect of on the self-excited generator (SEIG) used in the micro-grid system is investigated. The effect of the reduction of the electrical quantities generated voltage and its frequency following a purely resistive or inductive balanced or unbalanced load connection are studied in detail. A dynamic model of SEIG in the fixed reference axis dq is developed and simulated using Simulink / Matlab. The results of the simulations of different scenarios are discussed, and conclusions are deduced at the end of this article. These results will be used to study the stability of a micro-grid under a RT-LAB simulator in the future.
