摘要
广州市轨道交通十八号线及二十二号线,兼顾了国铁和地铁的特点,快速、客流量大、站间距大、车站数少,最高运行时速160km/h,连接了广州、珠海、东莞和中山等多个城市,是粤港澳大湾区的大动脉,两条线的功能定位介于干线铁路和城市轨道交通之间,具有干线铁路的速度目标,城市轨道交通的公交化服务特征。本文从多个方面分析了供电系统制式选型控制因素,并最终给出了供电制式选型建议,推荐采用AC 25kV供电制式。
Guangzhou metro line 18 and 22,take into account the characteristics of the national railway and subway.The two lines are fast,with large passenger traffic,large station spacing,and few stations.The maximum operating speed is 160km/h.It connects Guangzhou,Zhuhai,Dongguan,Zhongshan and other cities.It is the main artery of the Guangdong-Hong Kong-Macao Greater Bay Area.The functional positioning of the two lines is between the main line railway and urban rail transit,with the national railway speed target,and the service of urban rail transit.This paper analyzes the control factors of power supply system model selection from various aspects,and finally gives out suggestions for the selection of power supply system.It is recommended to use AC 25kV power supply system.
