Modeling, implementation and analysis of a high (six) phase self excited induction generator

Abstract Dual d-q model of six phase-self excited induction generator (6Ph-SEIG) developed in stationary reference frame is proposed in this paper. Developed model, implemented in terms of a simulation model, is utilized to evaluate no-load and on-load characteristics along with the estimation of dynamic parameters of studied 6Ph-SEIG for each working condition. Simulation results are verified on the implemented 6Ph-SEIG test-rig with high accuracy. Inherent loading limit of 6Ph-SEIG is obtained as 68% of the rated capacity with the evaluated optimum excitation capacitance of 4 μF per phase. The reactive power of SEIG varies from 4400 var to 600 var from no-load to maximum load of 1377 W with a corresponding change in magnetizing current from 4 A to 0.64 A.
