摘　　要：双馈调速能够实现转速和无功的独立调节,具有广阔的应用前景。矩阵变换器以其优良的特性成为双馈电机转子励磁电源的理想选择。建立了矩阵变换器励磁的双馈电机定子电压定向的矢量变换控制模型,利用MATLAB/Simulink仿真平台进行了仿真研究。仿真结果验证了该方案的正确性和有效性。Doubly-fed adjustable-speed system has independent regulating abilities of speed and reactive power, which has broad prospect in many industrial applications. Matrix converter can be used as excitation power supplies for such system with its excellent input and output characteristics and the ability of bidirectional power flow. The stator voltage-oriented vector control model of the doubly-fed machine fed by a matrix converter is developed and simulation study is made with MATLAB/Simulink software. The simulation results demonstrate the correctness and availability of the methods presented in this paper.
