Design advantages and analysis of a novel five-phase doubly-fed induction generator

Purpose The purpose of this paper is to provide an analysis the performance a new five-phase doubly fed induction generator (DFIG). Design/methodology/approach This presents results research work related DFIG framing, including development analytical model, FEM as well laboratory tests prototype. proposed behavioral level model based on winding function approach. developed was used at design stage simulate generator’s no-load and load state. Then, were shown compared with selected operating states. Findings provides simulation measurement dual-feed generator. use MATLAB Simscape modeling language allows for easy quick implementation model. Design assumptions model-based have been verified using measurements performed presented validate process show advantage over three-phase solution regarding control power quality. Research limitations/implications main disadvantage approach-based simplification omitting tangential airgap flux density component. However, fault only applies large machines insignificant in machines. analyses limited basic states generator, i.e. state, inductive resistive load. Practical implications novel five phase rotor can operate regular machine electric generation system improved quality electrical energy system. increase due windings inverter-based PWM supply voltage, which operates wider per-phase voltage range than phenomenon quantified current harmonic analysis.
