Deep Energy-saving and Consumption Reduction Strategies for Urban Rail Transit
Journal Title: Urban Mass Transit - Year 2024, Vol 27, Issue 8
Abstract
Objective With the increase in urban rail transit operational lines and operating hours, electrical energy consumption rises annually. To reduce energy consumption and operational costs, it is essential to conduct in-depth research on energy-saving and consumption reduction strategies for urban rail transit. Method The composition of electrical energy consumption in urban rail transit is analyzed, and influencing factors of train traction energy consumption, power equipment energy consumption, and lighting energy consumption are summarized. The strategies and practical applications of Nanning rail transit in energy-saving and consumption reduction are reviewed. Strategies and suggestions for urban rail transit deep energy-saving and consumption reduction in areas such as train traction, power equipment, and lighting. Result & Conclusion In 2022 to 2023, Nanning rail transit significantly reduced energy consumption by implementing strategies such as ATO (automatic train operation) traction and braking curve optimization, train air-conditioning control logic optimization, BAS (building automation system) optimization for enthalpy value, ′wind and water balance′ commissioning, lighting brightness adjustment. These strategies resulted in an annual energy saving of approximately 16 GWh per line. It is recommended that urban rail transit operating companies across various regions develop specific energy consumption and saving management measures tailored to their operational characteristics in aspects like line design, equipment and material selection, construction quality, operational organization, and management. This approach aims to achieve maximum energy savings and consumption reduction.
