Modeling and analysis of multi-phase (six-phase) self-excited induction generator

Self excitation in dual stator winding induction generator for renewable energy generation

“…In all the three cases, output is three-phase. Recently, two papers have reported on modeling and analysis of six-phase self excited induction generator [7,12]. However, so far as the authors have been able to ascertain, practical applications of multi-phase (comprising of more than the conventional three phases) induction generator in hydropower scheme are still unreported.…”

“…Multiphase drives system possess several advantages over conventional three-phase drives, such as reducing the amplitude and increasing the frequency of the torque pulsation, reducing the rotor harmonic currents, reducing the current per phase without increasing the voltage per phase, lowering the dc-link current harmonics, power segmentation and high reliability [1][2][3][4][5][6][7]. For this reason, multiphase induction machine drives are mainly related to the high-power and/or high-current applications such as for example in electric ship propulsion, in locomotive traction, in aerospace applications and electric/hybrid vehicles [15][16][17][18][19][20][21].…”

Performance Characteristics of Six-Phase Induction Generator for Renewable Power Generation

“…The multi-phase machine are considered advantageous as compared with its three phase counterpart as the rating of power is increased and high reliability requirements and additional number of phase added to the machine also brings additional freedom for improvements in the system, hence research in the area of multi-phase machines have been increasing. The first article on multi-phase induction generator [8] was published in the year 2005 which was added by some more work on sixphase induction generator [8][9][10][11][12]. The modeling and analysis of the six-phase induction generator was presented by Singh, et al, [8][9][10].The performance of the six-phase induction machine was discussed by Singh, et al, in [10][11][12].…”

Design and Implementation of a Multi-Phase Induction Machine Operating in generating Mode for Power Generation

“…A self excited induction generator operating in six phase mode has two stator winding sets namely abc and xyz , whose magnetic axes are displaced by an angle α [7]. The windings of each three-phase set are distributed and the axes are displaced 120 0 apart from each other.…”
