摘　　要：级联式无刷双馈电机(CDFM)在变速恒频(VSCF)发电方面有着广阔的应用前景。在分析CDFM的结构特点和工作原理的基础上,构建了该电机在转子速旋转坐标系下的数学模型,推导了VSCF运行模式下的控制策略。为了验证所提方案的正确性,对CDFM发电系统的VSCF运行模式进行了仿真试验。仿真结果验证了该控制策略能够实现有功功率和无功功率的独立控制,证明了该文所提方案的可行性。Cascade Brushless Doubly-fed Machine （CDFM） will have wide application in variable speed constant frequency （VSCF） generator fields, based on the design features and operating principle of CDFM, the mathematical model under rotor reference frame is derived and a novel power control strategy for VSCF is deduced as well. In order to examine such strategy＇s correctness, the computer simulation was carried out, the simulation results show the strategy is able to realize independent control for the active power and the reactive power and prove the power control strategy＇s feasibility.
