摘　　要：高速铁路一般使用AT供电方式。本文介绍3种AT供电模式:并从牵引变压器容量、牵引网输送容量和钢轨电位3方面对这3种供电模式进行对比分析。仿真结果表明新模式下的钢轨电位最大值较其他两种模式稍高,而对接触网的载流能力需求低于其他两种模式。法国模式对牵引变压器二次侧绕组容量要求较高,且需要中间抽头;日本模式居于两者之间。The autotransformer-feeding scheme is usually adopted in the high-speed railway systems.In this paper,three modes of AT-feeding scheme were briefly described and compared in respect of the secondary winding capacity of the traction transformer,transmission capacity of the overhead contact system（OCS） and rail potential.The results show as follows： for the novel mode,the maximum rail potential is just slightly higher than the other two while the transmission capacity demand of the OCS is the lowest among the three modes;the French-mode AT-feeding system requires higher capacity in the traction transformer secondary windings,and central tapping is needed;the performance indices of the Japanese mode remain neutral as compared with the other two modes.
