摘要

介绍了墨尔本地铁电传动系统的主要构成及其原理，根据用户对牵引系统的要求，利用Matlab 对其主电路进行仿真。通过对比不同固有频率( 通过改变电抗器L1 进行调节) 下的电压和电流数据，分析其对DC-DC 斩波器IGBT 管两端压降ΔU、中间直流电压Ud 以及网侧谐波电流、逆变器输入谐波电流的影响，同时建立斩波器故障模型，评估了故障情况下逆变器输入电压的特性，为主电路电气设计提供合理的选型和保护参考。

Abstract

The system structure and design principle of the electric drive system for Melbourne high capacity metro train were introduced, and according to the requirement of Melbourne owner, the main circuit was simulated by Matlab. The voltage drop between the two ends of the DC-DC converter’s IGBT, the intermediate DC link voltage Ud, and the harmonic current of grid side and inverter input were analyzed through comparing the voltage and current simulation data under different values of the inherent frequeney which were adjusted by changing the parameters of electric reactor LI. Meanwhile, through building DC-DC converter failure model, input voltage property of traction inverter was assessed in order to provide a reasonable reference for the design of the main circuit electric paramenters.
