Six-phase induction machine operating as a standalone self-excited induction generator

This paper deals with the use of multiphase induction machines in renewable energy applications such as wind and hydropower. Thus, some preliminary test results carried out on a six-phase induction machine operating as a stand-alone self-excited induction generator and supplying various loads under different conditions are presented. Firstly, the dynamic model of the power generation system is developed considering the magnetizing inductance saturation and excitation capacitors sizing to ensure the excitation task. Then, simulation and experimental results carried out on a 5.5 kW six-phase squirrel-cage induction generator are presented and discussed.
