State space modeling and performance analysis of self-excited induction generators for wind simulation

In recent years, it has been proven that one of the main issues in isolated applications is the importance of the dynamic characteristics assessment of three phase self-excited induction generator (SEIG). This paper presents a generalized state-space dynamic model using D-Q stationary reference frame of such a three phase SEIG. The values of self-excitation capacitance and the minimum and maximum speeds necessary to initialize the self-excitation are determined. The effect of variation of excitation capacitance and variation of SEIG loads are determined by simulation. The analysis of the results could help to determine the efficiency solutions for the system to supply isolated areas even when the loads are unbalanced.
