摘　　要：随着城际铁路不断发展,多类型列车、多复杂工况在同一供电线路联运必将成为趋势,这对牵引变电所的供电品质提出了更高要求,因此采用高精度、高频率的电能质量测试设备测量广清城际铁路新屋牵引变电所进线侧的A、B相电压及牵引母线电压,基于相关电能质量评估标准定量,评估其谐波、电压偏差,为相关铁路部门供电品质评估提供参考。With the continuous development of intercity railways,it will become a trend for multiple types of trains and complex working conditions to be intermodalized on the same power supply line,which puts forward higher requirements on the power supply quality of traction substations.Therefore,this paper adopts high-precision and high-frequency power quality testing equipment to measure the A and B phase voltages on the feeder side and traction bus voltages of the Xinwu traction substation,and quantitatively evaluates the harmonics and voltage deviation based on the relevant power quality assessment standards,so as to provide reference for the relevant railroad departments in evaluating the quality of power supply.

关 键 词：牵引变电所 谐波 电压偏差
