| 摘 要： | 在分析交流异步电动机数学模型的基础上,结合三电平中点钳位逆变器(NPC)输出谐波含量低、控制性能好等优点,论述了一种基于三电平的交流异步电动机直接控制的仿真建模方法。在Matllab/Simulink中建立独立的功能模块,搭建交流异步电动机直接转矩控制系统的仿真模型。仿真结果证明了该方法的合理性、有效性。

| Abstract: | Three-level neutral-point-champed (NPC) inverter was used in medium-voltage adjustable speed drive applications. In this paper, based on the mathematical model of AC asynchronism motor,a method for modeling and simulation of the three-level DTC system was presented in Matlab/ Simulink,and the independent functional blocks were modeled.The reasonability and validity were testified by the simulation results and this method offered a new thought for designing and debugging actual motors. |
