摘　　要：为了提高风能的利用率,针对现有开关磁阻发电机转子旋转的单一性,提出了一种新型可偏转双定子开关磁阻风力发电机,并介绍了该发电机的工作原理和控制机理。该电机采用内外双定子结构设计,在转子的两侧连接液压控制台,可实现多自由度偏转,适应不同风向,提高发电机的工作效率。通过对该电机建立数学模型,分析了发电机的电感、磁链、电压和电流的特性,利用有限元法对各物理量以及发电机转子外侧气隙磁场特性进行计算,将双定子结构开关磁阻发电机的输出电流仿真结果与普通开关磁阻发电机进行对比,验证了双定子结构发电机的优良性能。In order to improve wind energy utilization and solve the problem of the single rotation of the rotor of the existing switched reluctance generator,a new type of deflectable double stator switched reluctance wind driven generator was presented and its working principle and control mechanism were introduced.This generator adopts internal and external double stator structure design and the hydraulic console connected to the rotor can realize multi-degree of freedom deflection,adapt to different wind directions and improve the working efficiency of the generator.By establishing the mathematical model of the generator,the characteristics of the inductance,flux linkage,voltage and current of the motor were calculated.The physical quantities and the magnetic field characteristics outside the rotor were analyzed.The finite element method and comparing the output current of double stator structure switched reluctance generator was compared with common switched reluctance generator,the fine performance of the dual stator structure generator was verified.
