Feasibility Study on the Power Supply of DC 3-kV System in Urban Railway
Abstract
The DC (direct current) traction power supply calculation is important for the design of urban railway power supply system. Aiming at the introduction of DC 3-kV traction supply system in domestic urban railway transport, this paper proposes calculation principle and procedures detailedly; then, based on the certain line of Shenzhen subway, the comparison in the design scheme of DC 1.5-kV system and DC 3-kV system is carried out through calculation, and the feasibility and superiority of DC 3-kV system are assessed in the aspects of power supply technical index, power supply quality and so on.
