摘　　要：随着城市轨道交通的高速发展以及运行时间的进一步延长,在非高峰时段进行常规的停电检修维护已成为必要选择,而在进行常规检修工作时采用何种运行方式也成为亟待解决的问题。本文在城市轨道交通仿真平台的多列车运行模拟模块、交直流一体城轨牵引仿真模块以及运行图显示模块基础上开发了地铁设备停电检修维护决策平台。该决策平台以列车发车间隔、系统支援能力等影响因素为优化目标,以牵引网压、外部电源容量、馈线最大电流等作为约束条件,采用改进的暴力搜索算法并利用并行计算加速迭代,决策出N-1检修工况下最佳运行方式以及全部N-2故障工况下的最优解决方案。With the rapid development of urban rail transit and the progressive extension of operating time,it has become an indispensable choice to carry out routine power outage maintenance during off-peak hours,and the operation mode to be used during routine maintenance work has also become an urgent problem to be solved.The paper develops a subway equipment outage maintenance decision-making platform on the basis of multi-train operation simulation module,AC/DC integrated urban rail transit traction simulation module,and train diagram display module.This decision-making platform,with the influencing factors such as train departure intervals and system support capability as the target of optimization,with traction network voltage,capacity of external power source and maximum current of the feeders as the constraint condition,accelerates the iteration by application of improved brute force search algorithm and parallel computing.The optimized solution schemes are finalized for best operation mode under N-1 maintenance mode and optimized solution scheme under all N-2 fault mode.
