摘要
为查找福州市轨道交通1号线110 kV主变电站谐波超标原因,利用三相电能质量分析仪及建模平台对1号线主变电站110 kV进线、35 kV牵引动力负荷进行设备供电质量及消耗电能量的监测分析,对110 kV侧谐波超标的原因进行分析和对可能的谐波污染源进行查找。通过分析,确认谐波产生的主要原因为车辆牵引供电的整流和逆变装置,不可忽略的是公共电网的电能质量对地铁110 kV电能质量的叠加效应的影响。
In order to find out the cause of harmonic exceeding the standard in 110 kV main substation of Fuzhou Rail Transit Line 1, the three-phase power quality analyzer and modeling platform are used to monitor and analyze the power supply quality and power consumption of equipment for 110 kV incoming line and 35 kV traction power load in the main substation of Line 1, analyze the cause of harmonic exceeding the standard on 110 kV side,and search for possible harmonic pollution sources. Through analysis, it is confirmed that the main cause of harmonic generation is the rectifier and inverter device of vehicle traction power supply, and the influence of the power quality of public power grid on the superposition effect of subway 110 kV power quality cannot be ignored.
