Analysis of a double-stator induction machine used for a variable-speed/constant-frequency small-scale hydro/wind electric power generator

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

“…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]. Electric power systems have largely developed as three phase systems, although high phase order (in excess of three) machine construction and power transmission have been considered for last several years.…”

“…With the growth of increasingly sophisticated design methods and increased importance of economic, environmental and several other factors, the multi-phase systems are being considered as one of the potential alternatives to conventional three-phase systems. References [20,21] deal with the dual stator machine with extended rotor common to both stators. In all the three cases, output is three-phase.…”

Selection of capacitance for self-excited six-phase induction generator for stand-alone renewable energy generation

“…The generator scheme presented in [6] is based on dual stator winding induction machine with displaced power and control three-phase winding. References [7,8] deal with the double stator machine with extended rotor common to both the stators. In all the three cases, output is threephase.…”

Multiphase Wind Energy generation with direct matrix converter

“…These include the squirrel cage induction generator (SCIG), the doubly fed induction generator (DFIG), and the synchronous generator (SG) [5]. This paper proposes another electric generator for wind generation, a fivephase PMSG to generate electric energy from the wind integrated with matrix converter [6][7][8].…”
