摘　　要：市域铁路牵引供电系统相较于其他铁路牵引供电系统具有行车密度大、速度快、站间距短等特点,导致电压不平衡度、电压偏差、谐波等问题更加突出。以某市域铁路线路上的典型牵引变电所为例开展电能质量综合测试,并基于国家相关标准,对该牵引变电所电压不平衡度、电压偏差、谐波等电能质量指标进行了定量评估分析,为市域铁路电能质量问题的综合治理提供了依据。Urban railway traction power supply system has the characteristics of high traffic density,fast speed and short distance between stations,which leads to more prominent problems such as voltage unbalance,voltage deviation and harmonics than other railway traction power supply systems.Taking a typical traction substation on a municipal railway line as an example,a comprehensive test of power quality is carried out.Based on relevant national standards,the voltage unbalance,voltage deviation,harmonics and other power quality indicators of the traction substation are quantitatively evaluated and analyzed,which provides a basis for the comprehensive management of urban railway power quality problems.
