Pre-optimization of hybridization ratio in hybrid excitation synchronous machines using electrical circuits modelling

Hybridization ratio α is an additional degree of freedom offered by the hybrid excitation principle in design synchronous electrical machines. The first goal this contribution to present tool developed for analysing effect hybridization ratio. This software based on circuits modelling can also be advantageously used pre-optimization parameter. model and optimization algorithm are thoroughly detailed. Finally, a parametric study intended investigate some specifications parameters optimal value presented.
