本論文針對風力發電系統設計其無刷雙饋磁阻發電機(Brushless doubly-fed reluctance generator, BDFRG)，在符合所需之風能輸入條件下選擇合適的葉片，並考慮葉片輸出與發電機輸入間之匹配關係。考量風機調速上的需求，發電機在設計上具有控制繞組(Control winding)與功率繞組(Power winding)之雙繞組架構，然卻也造成其運轉中低轉矩密度的特性。因此本文利用「單位控制繞組電流產生最大轉矩」(Maximum torque per secondary ampere)的控制方式，以及透過具有較佳耦合性能之4/8極繞線(控制繞組4極，功率繞組8極)來深入探討高度非線性之磁通耦合下，兩定子繞組之磁動勢大小配置，並針對電機輸出特性加以分析，以改善其缺點。而本文亦透過磁阻轉子之幾何結構設計，改善BDFRG轉矩與轉矩漣波等特性，以提高其應用上的價值。最後提出針對此風力發電系統之設計法則及流程，並透過實驗與模擬驗證，以作為此電機未來發展重要的基底貢獻。

This thesis designs the Brushless doubly-fed reluctance generator (BDFRG) for wind power systems. A set of appropriate turbine blades is first selected according to the wind condition and required specifications. Then the BDFRG can be designed by considering the characteristic match between the turbine blades and the BDFRG. Considering the requirement of speed regulations for wind turbines, BDFRG is constructed with two sets of windings, including the control and power windings. However, this also causes low torque density performance in generator operation. To solve this problem, the thesis employs the “Maximum torque per secondary ampere (MTPSA)” control and the 4/8 poles windings (control winding 4P, power winding 8P) which have better coupling performance for allocation of the MMF between the two stator windings. Therefore, the output characteristics can be enhanced. Moreover, the torque and torque ripple of the generator can be also improved by the reluctance rotor design in this thesis. Finally, the experimental studies validates the proposed design of the BDFRG.
