Abstract

A DSP-based control scheme to simultaneously coordinate an AC/DC converter and a set of switched excitation capacitors of autonomous self-excited induction generators (SEIG). A laboratory 2.2 kW (3 hp) induction machine driven by a brushless DC motor is employed as the studied SEIG. Three-phase system model is employed to establish a set of complete system dynamic equations for simulating the performance of the studied system. The simulated results are compared with the measured outcomes to validate the proposed model. It can be concluded from the simulated and measured results that the proposed coordination control scheme can effectively maintain an adequate DC-link voltage profile at the output terminals of the AC/DC converter under various loading conditions.
