摘要
提出了一种新颖的六相感应电机调速系统的仿真模型。采用广义两轴正交实变换建立了静止坐标系下的六相感应电机的数学模型,给出其在Matlab/Simulink下仿真模型。研究了利用开关函数概念构成实用的六相电压源逆变器仿真模型的设计思想,给出采用Matlab/Simulink实现的具体步骤。整个调速系统模型简洁、方便,解决了仿真模型的收敛性问题,减少了计算时间。仿真结果表明该模型的有效性,为研究不同控制策略下系统的动态性能仿真奠定基础,并极易扩展到任意相交流电机调速系统的建模和仿真研究中。
A novel simulation model for six-phase induction machine drives is presented in this paper. Based on generalized two axis real transformation, a simulation model of six-phase induction machines using Matlab/Simulink is proposed in stationary reference frame. Also, the switching function concept is studied in order to establish the simulation model for the six-phase voltage-source inverter and the actual implementation of the model is explained in detail with the help of Matlab/Simulink. With the developed models, the drive circuit can be designed easily so that the convergence and the long run-time problem can be solved correspondingly. Simulation results are then presented to verify the effectiveness of the drive model, which lays the foundation for the study of the dynamic performance of the six-phase induction machine drives with different control methods and shows that it can be easily generalized to the modeling and simulation research of induction machine drives with arbitrary phase numbers.
