Abstract
In this project, a study design of a Ferrite Magnet-assisted Synchronous Generator (FMaSynRG) is realized, where a finite element method based software (OperaFEA) is employed. First, the simulation analysis of an existing 13-kW SynRM is done, whose electromagnetic parameters are calculated and compared with experimental ones. Then, the design of a 4-pole 5-MW FMaSynRG is performed by taking into account some physical rotor characteristics, such as asymmetric flux barriers and magnet coverage. These outcomes are contrasted with an 8-pole 5-MW IPMSG attaining similar results with lower active material weight. Finally, a wind power generation system is modelled with a FMaSynRG, where the MTPA strategy is employed. The controller design gets rid of the coupling terms and considers the computational and PWM delays due to the use of a digital controller.
