Multi-structure model to optimize a hybrid excitation synchronous generator

This paper proposes a multi-structure model combining eight rotating machines. The interest of double excitation is considered through magneto-motive sources combinations. An 1 MV prototype of Hybrid Synchronous machine with permanent magnets mounted on pole surfaces is presented and used to validate the studied model at no-load operating mode for two topologies. An optimization problem provides data for discussion on the industrial choices of the prototype structure.
