摘　　要：重庆轨道交通三号线已开通运营10年,实际客流需求已经超过设计要求。为了适应客流增加,满足行车组织需要,需评估重庆轨道交通三号线既有供电系统供电能力。依据GB 50458-2008《跨座式单轨交通设计规范》,提出重庆轨道交通三号线评估要求。根据重庆轨道交通三号线既有供电系统配置、列车牵引制动特性和线路平面与纵断面参数,以及行车组织要求,构建重庆轨道交通三号线供电系统仿真模型。依据仿真计算结果,评估重庆轨道交通三号线既有供电系统能力,得出重庆轨道交通三号线既有供电系统能力结论,提出提升供电能力措施,为重庆轨道交通三号线改造提供参考。Chongqing Rail Transit Line 3 has been in operation for 10 years,and the actual passenger flow demand has exceeded the design requirements.In order to adapt to the increase of passenger flow and meet the needs of traffic organization,it is necessary to evaluate the power supply capacity of the existing power supply system of Chongqing Rail Transit Line 3.According to GB 50458-2008 Code for design of straddle monorail transit,the evaluation re⁃quirements for Chongqing Rail Transit Line 3 are raised.According to the existing power supply system configuration,train traction and braking features,line plane and profile parameters and traffic organization requirements of Chongq⁃ing Rail Transit Line 3,the simulation model of power supply system of it is constructed.According to the simulation results,the existing power supply system capacity is evaluated,the conclusion of the existing power supply system ca⁃pacity is drawn,and the measures to improve the power supply capacity are raised to provide reference for the transfor⁃mation of Chongqing Rail Transit Line 3.
