摘　　要：文章从负荷特点入手,针对山区电气化铁路的特点,提出采用直供全并联供电方式解决200 km/h及以上客货共线山区电气化铁路供电难题,并从载流能力、牵引网电能损耗、牵引网电压损失等3个方面对全并联供电应用到山区电气化铁路中的供电能力进行了分析,得出在山区大坡道线路上,采用直供全并联供电方式供电能力基本同AT供电方式的结论。Based on the characteristics of electrified railway in mountainous area, this paper suggests that the difficult problem of power supply for electrified railway with a speed of 200 km/h or above in mountainous area should be solved with parallel-feeder mode. It also analyzes the power supply capacity of parallel-feeder mode applying to electrified railway in mountainous area from the three aspects as current carrying capacity, OCS＇s power loss and OCS＇s voltage loss.
