Novel rotor design of dual‐stator brushless doubly fed generator based on surrogate model

Dual-stator brushless doubly fed generator (DSBDFG) is a novel applied for wind power generation, and the electromechanical energy conversion between stator rotor realised by magnetic field modulation of special structure. Therefore, design critical to improve performance DSBDFG. In this study, different structures are compared analysed, position non-magnetic ring determined. order reduce computational cost optimisation efficiency, surrogate model coupled with multi-island geometric algorithm barrier layer cage rotor. addition, in effect skin on copper loss bars rotor, simulation models, whose have number, simulated analysed. Finally, experimental results verify correctness theoretical analysis effectiveness used
