Dynamic Modeling and Analysis of Six-Phase Self-Excited Induction Generator

This paper presents a simple d–q model of a saturated multi-phase (six-phase) self-excited induction generator (SP-SEIG). Multi-phase AC machines are nowadays widely considered as potentially viable solutions for numerous variable-speed drive applications. With an increased emphasis on renewable electric energy generation, while interfacing with the grid typically take place by means of power electronic converter, if the generator is used for stand-alone application. The main advantages of multi-phase machines that make them viable for drive can also be effectively exploited in generating application. In particular, it is shown that the SP-SEIG can operate with a single three-phase capacitor bank. The generator can also supply two separate three-phase loads, which represents an additional advantage. In this paper proposes the modeling and analysis of six phase self excited induction generator under R and RL load condition and also torque and rotor dynamic equation are discussed. The simulation results obtained and compared with three phases self excited induction generator. Results obtained compared with three phase self excited induction generator performance. In power generation application of practical usage this system has sufficient capability.
