A novel open-winding brushless doubly-fed reluctance machine and its power decoupling control system are proposed for wind power generator application. The control winding of brushless doubly-fed reluctance generator (BDFRG) is designed as open-winding structure, and the double-end power supply cascade two-level inverter is adopted to excite the open-winding BDFRG. This topology structure has better performance and fault redundancy capability, more flexible control modes, lower switching frequency and smaller inverter capacity. Moreover, for the special structure, the conventional vector control method is improved to decouple and to independently control the active and reactive power of open-winding BDFRG, in order to implement maximum power tracking. Finally, the effectiveness and feasibility of the proposed generation system is verified through the simulation study.
