Multiple approaches are pursued in the dynamic modeling of multi-phase SEIG analyses. However, the choice of the model remains arbitrary among the researchers and is based on convenience. This paper analyzes two well-known approaches-for dynamic modeling of a six-phase SEIG (6-θ SEIG). In the first model, the so-called dynamic cross-saturation effect on SEIG parameters is incorporated (Full-saturated model), and the second approach neglects the effect (Approximate model). To achieve the desired objectives, both models are derived mathematically and implemented in their respective simulation models after being duly validated experimentally. The operating characteristics of the 6-θ SEIG are extracted-during steady and transient states. The full-saturated model converges more with experiment results for transient events, including voltage build-up, loading, and sudden changes in 6-θ SEIG excitation capacitance. The experimental validations use a symmetrically wound, 2.2 kW, open-end winding (OeW) 6-θ SEIG driven by a prime mover (another 3-θ induction-machine).
