作者发明了一种上级风力涡轮机单元,它由串联的风力转子和双旋转电枢式发电机组成,而没有传统的定子。大尺寸的前风转子和小尺寸的后风转子分别驱动内电枢和外电枢,以保持旋转扭矩平衡。这样的操作条件能够使输出高于传统的风力涡轮机,并且在没有制动器和/或桨距控制机构的额定操作模式下保持输出恒定。前一篇文章介绍了串联式风力发电机转子的独特旋转条件和该装置的基本特性。在此基础上,通过实验研究了串联型风力机转子型线对机组性能的影响。理想的轮廓和主要结果如下。(1)最佳直径比为DRF(后部风转子直径除以前部风转子直径)= 0.84,两个风转子之间的轴向距离应设置得尽可能短。(2)与单个风力转子相比,当相对叶尖速比增加时,输出更高。
The authors have invented the superior wind turbine unit which is composed of the tandem wind rotors and the double rotational armature type generator without the traditional stator. The large-sized front wind rotor and the small-sized rear wind rotor drive the inner and the outer armatures respectively, in keeping the rotational torque counter-balanced. Such operating conditions may be able to make the output higher than the traditional wind turbines, and to keep the output constant in the rated operation mode without the brakes and/or the pitch control mechanism. The unique rotational conditions of the tandem wind rotors and the fundamental characteristics of this unit were presented at the previous paper. Continuously, this paper discusses experimentally the effects of the tandem wind rotor profiles on the characteristics of this unit. The desirable profiles and the main results are as follows. (1)The optimum diameter ratio is DRF (rear wind rotor diameter divided by the front wind rotor diameter) = 0.84, and the axial distance between both wind rotors should be set as short as possible. (2)The output is higher while the relative tip speed ratio increases as compared with the single wind rotor.
