Steady and transient state experimental investigation of the double output induction generator in autonomous operation

The operation and the experimental verification of an induction machine operating as double output induction generator, in autonomous situation, suitable for a wind energy conversion system are presented in this work. The system performance is studied considering the variations of the excitation voltage, and frequency and of the speed of rotation of the driving machine. The obtained results show the limits of stable operation and also indicate the possibilities of this system to achieve better utilisation of the available wind energy.
