摘　　要：多线合用牵引变电所运行条件复杂,实测数据更能反映牵引变电所真实的运行状况。首先分析了牵引变电所功率因数、三相电压不平衡、谐波等电能质量问题,然后基于实测数据对合蚌客专3座牵引变电所电能质量进行了分析。通过分析得出,牵引变电所电能质量符合国家标准要求,但是个别变电所存在高次谐波谐振问题。The operating conditions of the multi-line combined traction substation are complex,and the measured data can better reflect the real operation status of the traction substation.Firstly,the power quality problems such as power factor,three-phase voltage imbalance and harmonics of the traction substation are analyzed.Then,based on the measured data,the power quality of the three traction substations of Hebangke Special is analyzed.Through analysis,the power quality of traction substations meets the requirements of national standards,but individual substations have high-order harmonic resonance problems.
