摘要:
［目的］为解决传统运用车数计算方法不适用于蓄电池储能式有轨电车，以及列车运行图铺画过于繁琐的问题，提出一种运用车数计算公式修正方法。［方法］介绍了不受充电影响的传统运用车数计算方法；在此基础上，考虑有轨电车充电过程的影响，提出一种满足运营计划的蓄电池储能式有轨电车运用车数计算方法；提出计算假设，并介绍了各相关参数的计算方法；以某城市蓄电池储能式有轨电车线路的运用车数计算为例，用所提运用车数计算方法对列车上线运行达到续航里程后下线充电的情况进行分析。［结果及结论］将列车运行过程分为高峰前列车集中上线过程、列车线上运行过程、列车集中下线并向线上补充替换列车过程这3个阶段。通过计算所得的运用车数与通过列车运行图铺画的结果误差约为5%，说明所提运用车数计算方法能够满足运营要求并保有一定余量。
Abstracts:
［Objective］ To address the issues that the conventional method for calculating the number of VO (vehicles in operation) is not applicable to battery energy storage trams and the overly complex layout of train operation diagrams, a revised calculation formula for determining VO number is proposed. ［Method］ The conventional method for calculating VO number unaffected by charging is introduced. Based on this, taking the influence of tram charging process into account, a calculation method for determining VO number of battery energy storage trams that meets operational plan is proposed. Calculation assumptions are presented, and the calculation methods for various related parameters are described. Taking the VO number calculation of a battery energy storage tram line in a city as example, the proposed method is used to analyze the situation where the train goes off-line for charging after reaching the endurance mileage during on-line operation. ［Result & Conclusion］ The train operation process is divided into three stages: the concentrated on-line process before peak hours, the on-line train operation process, and the concentrated train off-line replacement and on-line supplement process. The calculated VO number has an error of approximately 5% compared to the results obtained through the layout of train operation diagram, indicating that the proposed method for calculating VO number can meet operational requirements with a certain margin.
