| 摘 要： | 直接转矩控制以其简洁明了的系统结构,优良的动、静态性能在感应电机的控制中得到了广泛应用。文中在分析了双馈感应电机直接转矩控制原理的基础上,提出了控制方案。该方案可以对电机转速、无功功率进行调节,使其工作在次同步、超同步、转子电流最小和定子侧功率因数补偿的运行状态。利用Matlab/Simulink进行了仿真研究,仿真结果证实了方案的可行性。

| Abstract: | As it has excellent dynamic capability and stability and simple control system,direct torque control(DTC) has been widely used in adjustable speed system for induction machines.In this paper a control scheme of doubly-fed induction motors(DFM) based on DTC is proposed.The theoretical analysis and control scheme are given.Applying this method the machine can be operated in sub-synchronous,super-synchronous speeds,minimum rotor currents mode and the stator power factor adjustable mode when adjusting the speed and reactive power.Matlab is adopted to simulate the system,and the results show that the scheme is reasonable. |
