A new control technique for dual stator induction generator used in standalone applications

Brushless Generation Systems are currently in great demand for remote area micro-grid application. Dual Stator Winding Induction Generator (DSWIG), having two windings on the stator of same pole configuration and a squirrel cage rotor, has been identified as one of the suitable candidates for such application. In most of the configurations proposed so far, one of the winding is responsible for power extraction and the other for maintaining desired excitation. This paper proposes a control algorithm which facilitates power extraction through both the stator windings. MATLAB/SIMULINK based simulation studies illustrate the efficacy of the control method. A dSPACE 1103 based laboratory prototype has been developed and experimental results are presented.
