Enhancing the performance of a stator and rotor combined-controlled wind-driven induction generator

Abstract EN

All experts have expected the rapid exhaust of the conventional energy resources.

Therefore, the utilization of wind energy is very important and finds nowadays great interest.

The present research Paper aims at enhancing the performance of winddriven induction generators at the different expected wind speeds employing control techniques from both the stator side and the rotor side.

The control from the stator is done via cycloconverter, while the control from the rotor side is done through the simple method of adding resistances in the rotor circuit.

The combined-controlled induction generator has been modelled at steady-state conditions using frequency domain equivalent circuit.

Computer-programs have been developed to compute the performance characteristics of the combined-controlled induction generator (CCIG) and the uncontrolled induction generator (UCIG).

The computed performance characteristics of the combined-controlled induction generator and the uncontrolled induction generator have revealed that the control of the induction generator through the stator cycloconverter and the rotor added-resistance has enabled capturing more energy from the wind.
