Study on energy consumption of multi-trains tracking on long heavy down grade of high-speed railway

Abstract

For the characteristics of high-speed train tracking operation on long heavy down grade of High-speed Railway, a cellular automaton dynamiccs model is proposed to simulate the energy consumption of multi-train tracking operation on long heavy down grade based on the NaSch model. Through numerical simulation, this paper studies the influence of different long slope value on the energy consumption of high-speed railway traffic flow. The simulation results show that the energy consumption model can accurately reflect the energy consumption of multi-train tracking operation on long heavy down grade. At the same time, the phenomenon of traffic waves that sometimes go and sometimes stop is reproduced. According to the simulation results, it can be concluded that the total energy consumption of multi-train tracking flow decreases gradually with the increase of slope value. The simulation results show that the energy consumption of starting, accelerating and decelerating of high-speed trains will decrease with the decrease of slope value. The results provide a scientific theoretical basis for efficient operation and energy-saving operation of high-speed railway. It has some guiding significance.

Review of Studies on Energy‐Efficient Train Operation in High‐Speed Railways

“…Maximizing the use of this regenerative braking energy depends on optimizing the scheduling scheme and driving strategy. Chen et al [79] developed an energy consumption model for tracking HST flow on the long heavy downgrade based on the NaSch model. The effect of different long heavy downgrades on the energy consumption of tracking HST flow was investigated using a cellular automaton dynamics model.…”

Calculation of the minimal length of the high-speed line

“…Another important question is energy consumption. This issue is the focus of other papers [15][16][17].…”

Empirical Study on the Sustainable Development of Mountain Tourism in the Early Stage of High-Speed Railways—Taking the Southwest Mountainous Region of China as an Example

“…The impact of HSRs on tourism is reflected in many aspects, such as local economic development [8], knowledge economy [9], sustainable development [10], tourism source market [11], tourism attraction [2,3], spatial spillover and economic growth [12], spatiotemporal accessibility [13], selectivity of tourism destination [14], tourism culture and language communication [7], and accessibility gains [15]. Moreover, on a positive note, it should be noted that mountainous areas are safe and reliable due to the fact that they have managed to overcome the negative impacts of earthquakes [16], wind load [17], and long slopes [18] in both railway infrastructure and locomotive and wagons.…”
