Subway System Energy Flow Management Model

With the development of economy, the process of countries transform to cities is graduallyaccelerated, and city track traffic system is in the high speed development. In addition to havinglarge passenger traffic volume, speed, less environmental pollution and time advantages, it isalso a symbol of modernization of city. At present, many cities strengthen the city railtransportation construction; some big city has already entered the city track transportationconstruction climax. As an important part of the track transportation system, Subway system isalso favored by the people; the subway has brought us convenience, but also created enormouselectric energy consumption. Under the situation of energy shortage in China and thedevelopment of a conservation-oriented society, achieving the energy-saving management isimminent.This paper firstly analyzes the subway system energy use and subway system energy flow,which is the base of land system in the energy flow model. Then, use the regression analysismethod to construct the train car consumption prediction model and energy consumptionprediction model of the subway station. Finally, based on the three models built the subwaysystem energy flow management model, and this model is based on the A city subway systemand puts forward the corresponding suggestions about energy saving. The main content of thispaper is to build an energy flow model, vehicle energy consumption prediction model and energyconsumption prediction model of subway station.For on-board energy consumption prediction model construction, it is mainly in Beijing andGuangzhou metro operation data analysis. Under the conditions of on the downhill routes andhas no downhill routes, using the regression analysis to establish models. Vehicle energyconsumption prediction model is based on the energy consumption of the degree of influence asthe basis, in turn influencing factors into the model. Finally, regarding the A city subway systemdata as the basis for the reliability of the model validation.Energy consumption forecast model of the station is mainly by the means of linearregression analysis method, established with the shielding door station ventilation and airconditioning load and the public area between a linear relationship, closed system stationventilation and air conditioning load and the public area between a linear relationship, escalator operation power and load rate and operating speed of between two yuan regression relationshipand dynamic lighting energy consumption and average temperature between a linear relationship.According to the above four kinds of statistics, the paper calculate A city subway system powerconsumption.The subway system energy flow management model is based on the subway system energyflow analysis as the basis, at the same time fusion on station and train energy consumptionprediction model constructed by regression analysis method, finally realize the subway systemenergy consumption prediction. Subway system energy flow management model explainselectric energy use link and process of the system from the perspective of the process, andrealizes the energy conservation management of Metro system. At the same time, through thefield survey and interviews, and model based, the paper put forward some suggestions aboutenergy saving for A city subway system.
