市域铁路牵引供电系统相较于高铁等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,电压不平衡度、电压偏差、谐波等问题更加突出.为了掌握市域铁路牵引供电品质特性,以某市域铁路典型牵引变电所为例开展供电品质综合测试.基于国家相关标准,对该典型牵引变电所电压不平衡度、电压偏差、谐波、三相电压不平衡度等电能质量指标进行了定量评估分析.
Measured Data-based Case Analysis of Power Quality Characteristics of Urban Railway
Compared with other railways like high-speed railways,traction power supply systems of urban railways subject to harsh working conditions,including high vehicle density,fast speed,and short inter-station distance,and therefore suffer more serious problems such as voltage unbalance,voltage deviation,and harmonics.Aiming at exploring supply quality characteristics of urban railway traction,this work performed comprehensive test on a typical case of urban railway traction substation.It then carried out quantitative assessment with respect to important power quality indexes,including voltage imbalance,voltage deviation,harmonics,and three-phase voltage imbalance,according to the relevant national standards.
