摘要
根据广梅汕铁路电气化改造前后的列车开行方案,定量分析了电气化改造前后的机车牵引能耗。广梅汕铁路电气化改造前,采用内燃机车牵引客货列车,每年牵引运输量为6.97×105万t.km,需要直接耗用柴油1.74万t,其能耗强度为36.38 kg标准煤/万t.km。电气化改造后,每年电力机车牵引运输量为9.29×105万t.km,每年需耗电1.05亿kW.h,按电力当量值计算,其能耗强度仅为13.89 kg标准煤/万t.km。电气化改造可大幅减少能源消耗,每年节约的能源折合1.25万t标准煤。
Based on the trains＇ schedules of Guangzhou-Meizhou-Shantou railway before and after its electrification reconstruction, we quantitively analyzed the locomotives energy consumption for traction. Before the electrification reconstruction, 17.4 kiloton diesel oil would be consumed by the diesel locomotives for 6.97 × 10^9 ton-kin tractions in each year. Correspondingly, the energy consumption intensity was 36.38 kg standard coal equivalent per ten-thousand ton-km. After the electrification reconstruction, 0. 105 billion kW · h power would be consumed by the electric locomotives for 9.29 × 10^9 ton-km tractions in each year. Correspondingly, the energy consumption intensity was 13.89 kg standard coal equivalent per ten-thousand ton-km. The electrification reconstruction could result in a great reduction of energy consumption for tractions, which meant that 12.5 thousand ton standard coal equivalent would be saved annually.
