| 摘 要： | 无刷双馈电机(BDFM)在风力发电系统中具有广阔的应用前景。其转子的磁场调制能力优劣直接影响着该类电机的功率密度和效率。基于笼型转子结构提出一种分段式笼型转子结构。介绍了BDFM的拓扑结构和变速恒频发电的基本原理,将几种笼型转子结构的BDFM进行有限元对比分析,深入研究转子导条间隔角度和导条层数对新型转子耦合能力的影响,确定了使得分段式笼型转子具有较强磁场调制能力的结构参数。结果表明:该新型转子结构在保证一定耦合能力的情况下,端部空间利用率更高,电机功率密度更大,且转子结构简单可靠、易于制造。

| Abstract: | Brushless doublyfed motor (BDFM) had promising application prospect in wind power generation. Coupling capability of rotor was an important factor affecting the power density and efficiency of the motor. Based on the analysis of structures of cage rotor, a segmented squirrelcage rotor was presented. At first, the topology of the BDFM and the principle of variablespeed constantfrequency (VSCF) generation were introduced. Secondly, analysis of BDFM with the above rotor structures was carried out using finite element software. Finally, the key parameters affecting the coupling capability were analyzed, such as spacing angle of rotor bars and layer number of rotor bars. The results showed that the new rotor structure held higher end space utilization ratio, higher motor power density and simple and reliable rotor structure under certain coupling capability. |
