Abstract

The difference and connection between energy consumption and energy efficiency are mathematically described for further study of energy-efficient rail transit system. Based on train behavior in the block section, we analyze the energy efficiency improvement of rail transit system in its life cycle. Then, the effects of train light-weighting, load ratio increase, and energy-saving train control scheme on the energy efficiency of rail transit system are simulated to verify the obtained analysis results. This research can contribute to the further study of energy-efficient rail transit system and promote energy consumption reduction and efficiency improvement.
