无刷双馈感应电机（bdfim）在过去的15年里得到了广泛的研究，因为在许多速度变化有限的应用中可能使用部分额定逆变器。然而，特殊的保持架转子结构和较大的转子损耗是这些机器的主要缺陷之一。一个类似的和非常有趣的机器，无刷双馈磁阻电机（BDFRM），在很大程度上被忽视了比较。这主要是由于磁阻转子设计不能产生足够大的显着比，使BDFRM与其他机器竞争。然而，在同步磁阻电机研究的推动下，磁阻转子的最新发展导致了经济建造的高显着比无笼转子。与BDFIM相比，BDFRM具有更高的效率和更简单的控制，这意味着BDFRM的进一步研究是有必要的。本文针对BDFRM最可能的应用-大型泵式调速驱动和变速恒频风力发电系统，对其重要的控制特性和相关的机器性能/逆变器尺寸权衡进行了比较理论分析。
Brushless doubly-fed induction machines (BDFIMs) have been extensively researched over the last 15 years because of the possibility of using a partially rated inverter in many applications with limited speed variations. However, the special cage rotor construction and substantial rotor losses is one of the key deficiencies of these machines. A similar and extremely interesting machine, the brushless doubly-fed reluctance machine (BDFRM), has been largely ignored in comparison. This was mainly due to the fact that reluctance rotor designs were not capable of generating saliency ratios large enough to make the BDFRM competitive with other machines. However recent developments in reluctance rotors, spurred on by research into synchronous reluctance machines, have resulted in high saliency ratio cageless rotors that are economic to build. This, together with the promise of higher efficiency and simpler control compared to the BDFIM, means that further investigation of the BDFRM is warranted. This paper presents a comparative theoretical analysis of the important control properties and related machine performance/inverter size trade-offs for the BDFRM in the light of its most likely applications-large pump type adjustable speed drives and variable speed constant frequency wind power generation systems.
