Abstract

Conventional short-pitched winding switched reluctance machine realizes the electromechanical energy conversion by utilizing only the rising region of phase inductance at motoring mode, or the descending region of phase inductance at generating mode. Compared with the conventional switched reluctance machine, the fully-pitched winding machine realizes the electromechanical energy conversion by utilizing both the rising and the descending regions of the mutual inductances among the phase windings. Thus, the fully-pitched winding switched reluctance machine shows more advantageous than the conventional switched reluctance machine. This paper proposes a novel generating control strategy of a three-phase fully-pitched winding switched reluctance machine, by introducing the generating operation principle of doubly salient electromagnetic machine into fully-pitched winding switched reluctance machine. With the novel control strategy, the fully-pitched winding doubly salient generator can afford convenient voltage-adjustable control without rotor angular position sensor. It is of low cost, high reliability, favorable voltage control, and shows great competitive in the applications, such as wind power generation, wave energy generation, flywheel energy storage, etc. The simulation and test results verify the novel strategy of fully-pitched winding doubly salient generator.

一种新型全倾斜绕组结构双凸极发电机

传统的短距绕组开关磁阻电机仅利用电机模式时相电感的上升区或发电模式时相电感的下降区来实现机电能量转换。与传统的开关磁阻电机相比，全螺距绕组电机利用相绕组间互感的上升区和下降区实现了机电能量的转换。因此，全螺距绕组开关磁阻电机比传统开关磁阻电机更具优势。本文将双凸极电磁电机的发电工作原理引入到全绕组开关磁阻电机中，提出了一种新的三相全绕组开关磁阻电机的发电控制策略。采用新颖的控制策略，使全坡度绕组双凸极发电机无需转子角位置传感器即可实现方便的电压可调控制。它具有成本低、可靠性高、电压控制性好等特点，在风力发电、波浪能发电、飞轮储能等领域具有很强的应用竞争力。仿真和试验结果验证了全坡度绕组双凸极发电机的新策略。
