摘要
以地铁运输能力提升至100 s发车间隔的供电系统安全为研究对象,分析考虑供电能力的列车运行调度优化策略。首先,运用层次分析法对地铁牵引供电系统供电能力建立分层分析模型并确定评估指标权重,基于云模型对正常双边供电和大双边供电方式进行评估,结合改进的云算法对评估指标计算得分选择最优方案,降低直流馈线峰值电流,消除直流保护过负荷跳闸隐患。最后,以北京地铁10号线运输能力提升至100 s发生间隔供电系统方案改造为实例进行模型验证。结果表明正常双边供电方案风险较低,为地铁供电系统工程改造提供理论依据。
Taking the safety of the power supply system with the subway transportation capacity increased to 100 s departure interval as the research object,the train operation scheduling optimization strategy is analyzed in considering the power supply capacity.Firstly,the analytic hierarchy process is used to establish a hierarchical analysis model for the power supply capacity of the subway traction power supply system and determine the weight of the evaluation index.Based on the cloud model,the normal bilateral power supply and the large bilateral power supply mode are evaluated.Combined with the improved cloud algorithm,the optimal scheme is selected to calculate the score of the evaluation index,reduce the peak current of the DC feeder and eliminate the hidden danger of DC protection overload tripping.Finally,the model verification is carried out by taking the transformation of the interval power supply system scheme of Beijing Metro Line 10 when the transportation capacity is increased to 100 s as an example.The results show that the risk of normal bilateral power supply scheme is low,which provides a theoretical basis for the engineering transformation of subway power supply system.
