Asynchronous generator model for autonomous operating mode

The paper deals with the modeling of a three-phase self-excited induction generator and its steady state analysis using space vector formalism. The behavior of an induction generator working in autonomous mode and which supply an inductive resistive load is presented using a numerical model developed in Matlab-simulink. The startup phenomenon and the problematic which appear for this working mode are presented and discussed leaning on the simulated results obtained from various studied cases. Computed characteristics have been verified experimentally in laboratory using three-phase squirrel-cage induction machine. Significant agreement between experimentally and simulated results obtained with proposed numerical model is shown in the paper.
