A new grid-connected system for axial field flux-switching permanent magnet wind power generator

This paper presents a new grid-connected strategy for axial field flux-switching permanent magnet (AFFSPM) wind power generator with improved dynamic response and steady-state performance. Non-controllable convertor and grid-connected PWM rectifier are used as the structure of the main circuit. Triple-state direct power control(DPC) strategy is used on grid side to improve the accuracy of power decoupling. Both simulation and experiment results are showed to demonstrate the strategy is available and has advantages of simple structure and high power factor.
