摘要
结合城市轨道交通供电系统课程的教学需要,基于MATLAB GUI和Simulink设计了城市轨道牵引整流机组仿真系统。通过GUI设计人机交互界面,利用Simulink搭建了包括24脉波整流机组、12脉波整流机组和48脉波整流机组的底层仿真模型。用户可以通过人机交互界面,选择输入电压和不同类型的整流机组仿真模型进行仿真实验。最后,以35 kV、50 Hz的输入电压为例,进行24脉波和12脉波整流机组仿真实验,比较两种整流机组的整流结果,并对实验结果进行谐波分析。仿真实验结果表明:系统操作简单直观,能够帮助学生更好地理解城市轨道牵引整流机组的工作原理。
Combined with the teaching needs of the course of urban rail transit power supply system,a simula-tion system of urban rail traction rectifier unit is designed based on MATLAB GUI and Simulink.The human computer interaction interface is designed through GUI,and the underlying simulation model including 24-pulse rectifier unit,12-pulse rectifier unit and 48-pulse rectifier unit is built by Simulink.Users can select the input voltage and different types of rectifier unit simulation models for simulation experiments through the human-com-puter interaction interface.Finally,taking the input voltage of 35 kV and 50 Hz as an example,the simulation ex-periments of 24-pulse and 12-pulse rectifier units are carried out to compare the rectification results of the two rectifier units,and the harmonic analysis of the experimental results is carried out.The simulation results show that the system operation is simple and intuitive,which can help students better understand the working principle of urban rail traction rectifier unit.
