Problems solved by technology

[0005] At present, the energy consumption calculation method of urban rail transit electric traction trains still has the following problems: First, in the previous system design, the designer usually can only give a certain part of the power of the train, and can only estimate the energy consumption of this equipment, for example, according to the train Traction Motor Characteristics Estimation of Energy Consumption During Traction Phase
If the calculation method of train energy consumption is unreasonable or inaccurate, it will cause the entire system to fail to achieve the expected goal of energy saving and emission reduction

Abstract

The invention discloses a calculation method oriented to single-train running energy consumption of urban rail transit in the field of evaluation of electric traction train energy consumption of urban rail transit. The method comprises the steps of firstly establishing a train traction model by analyzing car performance, line conditions and a signal system, and calculating the instantaneous power and the accumulative energy consumption of a traction system based on the running speed, the running position and the running time of a train; then establishing a train auxiliary system model by analyzing car configuration equipment, and calculating the instantaneous power and the accumulative energy consumption of an auxiliary system based on elements such as rated power and running time; and finally calculating the total running energy consumption of a single train based on traction energy consumption data and auxiliary energy consumption data. The calculation method disclosed by the invention can be used for respectively calculating the energy consumption of the train traction system and the auxiliary system. When train parameters or the line conditions are changed, the train running energy consumption can be more flexibly calculated by using the method.

Description

technical field [0001] The invention belongs to the field of evaluation of energy consumption of rail transit electric traction trains, and in particular relates to a calculation method for running energy consumption of a single train in urban rail transit. Background technique [0002] Rail transit is the most sustainable mode of transportation. Urban rail transit is often used as the main line of urban transportation, shouldering the burden of reducing traffic congestion and realizing energy saving and emission reduction. In recent years, the research on energy saving and emission reduction of urban rail transit has attracted more and more scholars' attention. In order to save the energy consumption of the urban rail transit system, it is necessary to determine the energy-consuming equipment and its energy-consuming mechanism in the system, and evaluate its energy consumption on this basis. There are two main types of energy consumption of urban rail transit trains: one ...
