摘要
城轨再生能馈装置代表了列车再生电能利用技术的发展方向,随着其不断得到推广应用,需要编排合理有效的维修计划,以确保城轨牵引供电系统可靠经济运行。本文采用GO-FLOW法建立城轨再生能馈装置的动态可靠性模型,以可靠性和维修费用为优化目标,进行了改进的多目标优化计算,与单目标优化结果对比表明,多目标优化方法在经济性和稳定性的综合优化方面具有优势。
The urban rail regenerative energy feedback device represents the development direction of train regenerative energy utilization technology.With its continuous promotion and application,it is necessary to arrange a reasonable and effective maintenance plan to ensure the reliable and economical operation of the urban rail traction power supply system.The paper established a dynamic reliability model for regenerative energy feedback device of urban rail transit by application of the GO-FLOW method,with reliability and maintenance costs as optimization objectives,carries out an improved multi-objective optimization calculation.The comparison with single objective optimization results shows that the multi-objective optimization method has advantages in comprehensive optimization in terms of economy and stability.
