摘　　要：侯月线沁水—嘉峰下行方向因供电臂长、车流量大、电压损耗大,多次发生阻抗保护动作,且末端分区所电压最低为16 kV左右,严重影响运输生产。本文对该区段牵引供电运行方式进行优化研究,以提高供电质量。In section from Qinshui-Jiafeng on Houma-Yueshan railway,since its downward power supply section is long,within which there is heavy traffic and great loss of voltage,so impedance protection actions occurred for many times.At the most severe case,the lowest voltage in the sectioning post is even 16 kV.Therefore,the transport and production are seriously interfered.The paper studies the optimization of the traction power supply operation mode in the section so as to improve the power supply quality.
