Abstract: Considering the dynamic change of passenger flow, a refined calculation method for comprehensive operation energy consumption of urban rail transit is put forward. Comprehensive operation energy consumption mainly includes energy consumption of train traction,ventilation and air conditioning system, and escalator. Taking a section of Beijing Metro Line 8 as an example, the energy consumption is calculated in detail. Results show that the energy consumption distribution matches with the morning and evening rush hour distribution, verifying the accuracy and feasibility of urban rail transit comprehensive energy consumption calculation method.
