Simple control for a wind-driven induction generator

A new induction generator controller has been presented in this article. The proposed controller is suitable for variable-speed, constant-voltage operation. The controller is suitable for all sorts of practical loads including reactive, harmonic and imbalanced loads. The simulation and experimental results show that the generated three-phase voltages are balanced and identical. The transient and steady-state responses of this scheme are good, with only one or two cycles required to overcome the transient disturbance. The controller is simple and cost effective, yet the performance is good.
