摘　　要：青藏铁路那曲至沱沱河段35kV电缆贯通线路可作为青藏铁路无人区的电源保障。因缺少电源点支持,故在供电臂长度选择方面做了创新性尝试。在仿真计算的基础上对线路运行的可行性与可靠性进行了验证,并通过对各种运行方式及故障情况的仿真分析,对电缆供电线路的中性点接地方式做了优化选择。Considered the reliability of the power supply of Qinghai-Tibet Railway, a new 35kV cable line was built from Naqu to Tuotuohe River as a power source backup. Because of lack of power support, the design is creative, which have a long power supply distance for cable lines. The feasibility and reliability are researched in this paper, and the neutral point grounding mode of the cable line is optimized based on the simulations.
