A NOVEL SELF-EXCITED SELF-REGULATED SINGLE-PHASE INDUCTION GENERATOR

Part I of this paper presents the basic system, theoretical modelling and typical test results of a novel Self-Excited Self Regulated Induct ion Generator. In this part the results of a detailed experimental inv estigation are presented to assess its suitability for practical appli cations. The steady state performance of the self-excited single phase induction generator (SEIG), maintaining the terminal voltage within a dose 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 modellin g are also developed and relevant results of the prototype presented. The effects of series and shunt capacitors, prime mover speed, load an d load power factor and investigated. It has been shown to exhibit bet ter voltage waveform as compared to commercially available sets. The e xperimental results confirm that this new generating system can be fav ourably employed for use as a small portable generator driven by nearl y constant speed prime movers such as oil engines or Hydro Turbines.
