高速磁浮系统能耗与效率分析

该文分析轨道交通能耗和效率表征节能的差异,效率高是系统能耗低的必要条件。通过研究不同牵引电机及牵引系统架构,分析高速磁浮、轮轨和中低速磁浮的各自系统效率,高速磁浮牵引电能传输转换效率与轮轨相当,远高于中低速磁浮的系统效率。研究不同制式的轨道交通阻力成分,分析不同速度下的能耗水平及不同制式的能耗比较,同速度级高速磁浮能耗水平与高速轮轨相当。最后高速磁浮拥有更高速度运行的能力,600 km/h运行时系统效率达83%以上。

The paper analyzes the difference between energy consumption and efficiency of rail transport, and points out that high efficiency is necessary for low energy consumption. By studying different traction motors and traction system architectures, the efficiencies of high-speed maglev, wheel-rail and medium-low speed maglev are analyzed. The efficiency of high-speed maglev traction is equivalent to that of wheel-rail, which is much higher than medium-low speed maglev system. The rail transport resis-tance of different systems is studied, and the energy consumption at different speeds and the energy consumption comparison of different systems are analyzed. The energy consumption of high-speed maglev is equivalent to that of high-speed wheel-rail at the same speed level. Finally, the high-speed maglev has the ability to operate at higher speed, and the system efficiency reaches more than 83% at 600 km/h.
