牵引供电系统用移动式串联电容补偿方案探讨

针对线路坡度大、牵引负荷重的山区电气化铁路在开行货车且进行越区供电时,接触网末端电压水平经常低于设计规范要求的最低电压19 kV的要求,很难满足运输组织的需要,以丽江—香格里拉铁路为例,提出了区间移动式串联电容补偿方案,可以提高接触网末端电压水平,保障牵引供电系统越区时的运输要求,且较为节省投资。

Discussion of Scheme of Mobile Series Capacitance Compensation for Traction Power Supply System

In this paper,based on the large line slope,heavy load weight,mountain electrified railway traction supply power for freight train over the fault substation power,the terminal voltage levels of catenary are often below the design specification requires a minimum voltage of 19 kV requirements,it is difficult to meet the transportation needs of the organization,Take the Lijiang to Xianggelila railway as an example,the range mobile series capacitor compensation program,can raise the level of the end of the catenary voltage,to protect the transport requirements of the traction power supply system,and save investment.
