Abstract

: A novelty dual-stator brushless doubly-fed generator (DSBDFG) with magnetic-barrier rotor structure is put forward for application in wind power. Compared with a doubly-fed induction generator, the DSBDFG has virtues of high reliability and low maintenance costs because of elimination of brush and sliprings components. Therefore, the proposed structure has tremendous potential as a wind power generator to apply in wind power. According to the operating principle of electric machine, the DSBDFG is studied in wind power application. At ﬁrst, the topology, the winding connecting, the rotor structure, the power ﬂow chart of diﬀerent operating models and the variable speed capability of electric machine are discussed and analyzed. Then, a 50 kW DSBDFG is designed. Based on the principal dimension of the design electric machine, the electromagnetic characteristics of the DSBDFG with diﬀerent running modes are analyzed and calculated to adopt the numerical method. From the result, it meets the requests of electromagnetic consistency and winding connecting in the design electric machine. Meanwhile, it conﬁrms the proposed DSBDFG has the strong ability of speed regulation

用于风力发电的双定子无刷双馈发电机

提出了一种新型的双定子无刷双馈发电机(DSBDFG)，该发电机具有磁障转子结构，可用于风力发电。与双馈感应发电机相比，DSBDFG由于消除了电刷和滑块元件，具有可靠性高、维护成本低的优点。因此，所提出的结构作为风力发电机应用于风力发电具有巨大的潜力。根据电机的工作原理，研究了DSBDFG在风力发电中的应用。首先对电机的拓扑结构、绕组连接、转子结构、不同运行模式下的功率流程图以及电机的变速能力进行了讨论和分析。然后，设计了50kw的DSBDFG。在设计电机主尺寸的基础上，采用数值方法对DSBDFG在不同运行模式下的电磁特性进行了分析和计算。结果表明，满足设计电机的电磁一致性和绕组连接要求。同时，验证了所提出的DSBDFG具有较强的调速能力

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
