摘　　要：以绕线式异步电机为研究对象,采用定子电压矢量控制约束,建立了转子交流励磁变速恒频发电机的矢量控制模型,并基于MATLAB/Simulink平台构建了系统的仿真模型.仿真结果和分析表明,转子交流励磁电流实行矢量控制的变速恒频发电机能实现机电之间的充分解耦,发电机定子电压(或电流)的频率和相位与转子的实际转速无关,实现理论上机电之间的柔性连接,对高品质柔性电力系统的研究和机电系统的建模仿真亦具有参考价值.On the basis of the stator field-oriented control, the control model and strategy for a variable speed constant frequency generator with an AC-excited wound rotor was investigated. Simulation model of the system in Matlab/Simulink was built. Results show that the frequency and phase of the stator voltage or current are independent of the rotor speed and its instantaneous position. A full decoupling between the mechanical port and electrical port is possible and a flexible connection in the electro-mechanical system can be realized, much more significant and valuable for the research of highperformance flexible power system.
