| 摘 要： | 针对同相AT牵引供电系统,提出了一种采用全并联AT的双边供电(或多电源供电)的牵引网供电方式,对其电能损失在理论上与现有的AT分区所并联的单边供电系统进行了比较,优越性显而易见,并进一步对其供电臂的保护控制方案进行了分析.该牵引网供电方式能使负荷在上下行以及多个供电臂内进行均衡,有较好的供电质量,满足高速、重载的牵引发展要求.

| Abstract: | As to the cophase AT traction power supply system, a double-end (or multi power supply) feeding system with all-parallel AT is proposed. Its electrical energy loss is compared in theory with the existing single-end feeding system with AT-parallel only in the section posts and its advantages are obvious, furthermore, the protection and control system of its feed sections is analyzed. The proposed feeding system can proportion the load in double-line and some feed sections. With the good power supply quality, it satisfies the requirement of the high speed and overloading railway development. |
