摘　　要：随着多电/全电飞机概念的提出以及机上用电设备的增加,对飞机供电系统电能容量与质量提出了更高的要求。传统三级式同步发电机采用恒速传动装置,不但增加了机载重量,而且发电机容量不能做到很大。为解决优化问题,提出一种串级式航空无刷双馈变速恒频交流发电机,在减少飞机重量的同时可满足对发电机大容量的要求;在对串级式无刷双馈发电机组成和工作原理研究分析的基础上,结合矢量控制算法在Matlab/simulink环境下建立其仿真模型并进行了仿真研究。结果表明:系统运行具有良好的动态特性;所建立的模型是正确的,所采用的方法是可行的。As more-electric/all-electric aircraft concept proposed and electrical equipment increasing,the quality and capacity of the power supply systems of the aircraft is taken higher demands.Traditional three synchronous generator uses constant speed drive unit,but it not only increases the load capacity,but also limits the generator capacity.The paper presented a cascade aviation brushless doubly-fed variable speed constant frequency alternator,at the same time,reduced the weight of the aircraft to meet the requirements of large-capacity generator.On the basis of analysis of the composition and working principle of the cascade brushless doubly-fed generator,the model has been established and simulated in Matlab/simulink environment combined with vector control algorithm.The results show that：the system has good dynamic characteristics,and the established model is correct and feasible.
