摘要
我国城市轨道交通发展突飞猛进,但其采用的直流供电系统的缺陷不可避免,如杂散电流危害、直流电机换向困难、共用中压环网影响等。论文介绍了城市轨道交通交流供电系统,并与既有的直流牵引系统比较,从主变压器容量、主变电所数量、环网电缆用量、地下车站建设、运营检修成本方面,浅析了城市轨道交通交流供电系统的经济性。
The development of urban rail transit in our country is advancing by leaps and bounds, but the defects of the DC power supply system are inevitable, such as stray current hazards, DC motor commutation difficulties, and the effects of common use of medium voltage ring networks and so on. This paper introduces AC power supply system for urban rail transit, compared with the DC traction power system, and based on the main transformer capacity, the number of main substation, the amount of cable network cable, the construction of underground station and the cost of operation and maintenance, the economy of urban rail transit power supply system is analyzed.
