地铁电动车组交流牵引计算与仿真分析

Calculation and simulation analysis of AC traction for metro EMUs

提出了一种地铁电动车组交流牵引计算模型,介绍了基于Windows环境下所开发的相应的系统仿真程序,并用实例进行了分析和计算,其结果达到了国外设计公司提供的可行性分析报告的要求,也与上海地铁2号线工程的实际运行情况基本一致。该软件通过模拟地铁电动车组的实际运行,计算出电动车组的运行距离、运行速度、从接触网受取功率(或电流)以及能耗等随时间的变化量。然后,再将这些数据经过功能性处理,以满足不同的实际要求。

A calculation model is proposed for the AC traction of metro EMUs. The system simulation program based on Windowsoperating system is put forward. Analyses and calculations with practical examples show that requirement from the feasibility analysisreport by foreign design companies have been reached. And the results are in general conformance with the practical running data ofShanghai metro line 2. By simulating the practical operation of metro EMUs, the software calculates the time variables such as the runningdistances, speeds, power/current fed from the catenary and energy loss of the EMUs. These data might satisfy different demands afterfunctional processing.
