Integrated Energy Consumption Simulation Platform Of Urban Rail Transit

Urban rail transit has the characteristics of high speed,convenience,energy saving and so on.It is developing rapidly all over the world,and its operation energy consumption is increasing.The energy consumption of traction power supply of the train accounts for more than 40% of the total energy consumption of urban rail system.Therefore,the study of energy-saving operation control of the train is an important way to reduce the energy consumption of urban rail.The train energy-saving operation control is a multi-disciplinary integration field,involving transportation organization,train operation control and power supply,so the integration of energy-saving has increasingly become the research direction of many scholars.However,at present,the integrated energy-saving research lacks the means of simulation and data support,and the field test consumes human and material resources.Therefore,the research and implementation of urban rail integrated energy consumption simulation platform is of great significance and use value.Firstly,aiming at the integrated simulation platform of multi train operation energy consumption,according to the actual demand of energy consumption simulation of urban rail system,this paper constructs the overall framework of the integrated simulation platform,which mainly includes three simulation modules of train diagram simulation,ATO simulation,traction power supply simulation and data visualization display interface.Secondly,it introduces the simulation methods and theoretical basis adopted by each module,and designs the implementation scheme of the integrated energy consumption simulation platform based on the comprehensive requirements and theoretical basis,including the definition of the functions and software architecture of each module,the design of functional zoning and data visualization effect,and the provisions of the storage mode,data structure and form of various data in the integrated energy consumption platform.Finally,visual studio 2015 is used as the development tool and C# as the main development language.Based on Ado.Net technology,MATLAB and C# mixed programming technology and HTML5 visual development technology,the development of urban rail integrated energy consumption simulation platform is completed.Finally,it realizes the input of train schedule,basic data of line and power supply,and the simulation calculation of all day train operation data,energy consumption data and network energy consumption data.It provides simulation and data support for integrated energy saving research.
