Vector control system of a self-excited induction generator including iron losses and magnetic saturation

We propose a novel indirect rotor-flux-oriented control system of a self-excited induction generator with online calculated iron losses and magnetic saturation. Within the control system, the iron loss resistance is represented as a function of both the synchronous frequency and magnetizing flux, and the magnetizing inductance is represented as a function of the magnetizing current. Both iron losses and saturation characteristics were determined from no-load tests. The effectiveness of the proposed approach is verified through both simulations and experiments. Through a comparison with the conventional approach, insight is provided into the efficiency estimation error and detuning due to iron losses.
