A novel self-exited self-regulated single phase induction generator. II. Experimental investigation

Part I of this paper presents the basic system, theoretical modelling and typical test results of a novel self-excited self regulated induction generator. In this part, the results of a detailed experimental investigation are presented to assess its suitability for practical applications. The steady state performance of the self-excited single phase induction generator, maintaining the terminal voltage within a close range is investigated under realistic loading conditions in the laboratory. Detailed experimental results are presented and discussed. Necessary tests to obtain machine parameters for theoretical modelling are also developed and relevant results of the prototype presented. The effects of series and shunt capacitors, prime mover speed, load and load power factor are investigated. It has been shown to exhibit a better voltage waveform as compared to commercially available sets. The experimental results confirm that this new generating system can be favourably employed for use as a small portable generator driven by nearly constant speed prime movers such as oil engines or hydro turbines.<
