摘 要:针对地铁车辆辅助供电系统的冗余性问题,宁波轨道交通4号线和2号线二期工程地铁车辆采用并网供电和高频变流技术,并采用4动2拖6节编组方式,由4台并网供电的辅助逆变器提供AC 380 V交流电源,4台充电机为列车DC110V控制电路和直流负载供电,并为列车蓄电池充电。文章阐述了宁波轨道交通4号线和2号线二期工程地铁车辆供电系统电路组成、原理和特点。并网供电技术的应用可以提高地铁车辆辅助供电系统的冗余性。For the purpose of improving the redundancy of the auxiliary power supply system of the metro vehicles, the grid connected power supply technology and the high-frequency converter technology were applied to line 4 and line 2 phase Ⅱ project of the Ningbo metro. 4 SIV were grid connected to provide AC 380 V to the metro vehicles which grouping up with 4 motor cars and 2 trail cars. Meanwhile, 4 DC charger provided DC 110 V to the DC control circuit and the storage battery. The circuit composition, principle and characteristics of metro vehicle power supply system of Ningbo rail transit line 4 and line 2 phase Ⅱ project were expounded. The application of grid connected power supply technology would improve the redundancy of auxiliary power supply system of metro vehicles.
