Study On The Power Consumption Of Traction And Station Of Urban Rail Transit

The rapid development of urban rail transport in easing traffic jams and facilitating the public to travel at the same time, it has also brought a rapid increase in electricity consumption. At present, in China's building of a conservation-oriented society, a conservation-oriented context of urban transportation, urban rail transport as the biggest power infrastructure projects, its energy problem has been more and more attentioned. However, In order to study the rail transit lines at the actual operating conditions, vehicle type, passenger traffic, such as the impact of its energy consumption, energy consumption and the impact of the station, in this paper, we consider Guangzhou, Beijing Metro Line operator status of into the investigation, a reliable Data for the rail transit system for the energy consumption of the stage, it is of important practical significance.For the automotive power, we consider the South, the North urban rail transport vehicles for automotive air-conditioning the impact of energy consumption, using regression analysis, the impact of traction energy consumption of major factors, in accordance with its role in the energy consumption level of sizes, Followed by the introduction of the regression equation, the establishment of the South, the North energy consumption of urban rail transport vehicles of the mathematical model. For the power station, using linear regression approach, the establishment of a PSD station ventilation and air conditioning load and the public area of the station a linear model, the station closed system ventilation and air conditioning load and the public area of the station a linear model, automatically the escalator and running full power and speed of the dual regression model, and use of lighting power density and intensity to calculate the station area of public lighting in the consumption of electricity, according to statistics from these three aspects of the power station. The Shanghai Metro Line operator of the actual data on the southern city of rail transportation vehicle energy consumption model has been tested and verified the results in good agreement.It is established by the rail transportation and energy consumption model of energy consumption in this paper, with a view to urban rail transport lines to increase the planning and design of a power-sharing ratio of the reference conditions, for the operational phase to lay a foundation for reducing energy consumption.
