摘要
We present a new voltage controller for an induction generator in an autonomous power system. The controller acts via a PWM inverter which is connected in parallel with the induction generator and maintains a constant voltage magnitude at the generator terminals. In addition to this voltage regulation, the controller successfully eliminates harmonic distortions caused by nonlinear loads. Unlike earlier controllers designed for such a system, our controller is not based on a hysteresis rule. It incorporates a finite dimensional internal model with adjustable resonant frequencies and a stabilizing compensator designed using genetic optimization combined with H-infinity design. The proposed controller can be implemented digitally with synchronous sampling. To examine the performance of this controller, computer simulations of a full power system model were carried out in Simulink (R). The results show the advantages of the new voltage controller.
