| 摘 要： | 在同步电机、交交变频器和磁场定向控制系统方程的基础上，提出了磁场定向控制交交变频同步电机系统完整的数学模型。编制了相应的数字模拟程序，采用四阶龙格一库塔法解同步电机的状态方程，而离散相似法用于控制系统方程的求解。在实验室建立了由一台４０ｋＷ三相凸极同步电机、交交变频器和磁场定向控制系统组成的小容量试验系统。进行了两种情况的动态实验，并与相应的仿真结果进行了对比。比较结果表明了上述数学模型的正确性。

| Abstract: | On the basis of the model of synchronous machine,cycloconverter and field-oriented control system,an integrated mathematic model of the field--oriented control cycloconverter-fed synchronous machine system is presented in this paper. The corresponding digitalsimulating program has been developed. In the simulation 4-step Runge-Kutta method isadopted to solve the state equation of the machine, and discrete similitude method is. used forthe control system. An experimental system composed of a 40 kW three-phase salient polesynchronous machine, cycloconverter and field-oriented control system has been established.Simulation and experiments are carried out on such a system for two dynamic conditions.Comparison between experiment and simulation indicates the aecliracy o-f the.\mathematicmodel. |
