Title    Modeling and simulation on metro power supply  system which contains vehicle braking resistor                                                

Abstract

With the development of economic construction，rapidly increased of transport especially the city traffic grows by several times. The problem of traffic is becoming more and more serious. Founding urban rail transit has become the important measures to solve the problem of urban traffic.    

The research background and significance are introduced in the first in this dissertation. The main methods of modeling and means of simulation of urban rail transit system in the overseas and domestic were analyzed then. Operating a comprehensive simulation of DC traction power supply system of urban rail transit. Analysis of the composition of the metro power supply system is analyzed, especially the traction power supply system. And then, this dissertation introduces and analyzes the using and characteristics of vehicle braking resistance, which provides necessary reference for the following modeling and simulation of system. The whole model of DC traction power system including traction substation, contact network, train and back track was built in this article, and the working condition of the vehicle braking resistor is also taken into account. Simulation of Dc side network of rail transit traction power supply system is done after above. In the end, for the content of software implementations described herein. This dissertation introduces the development environment of process engineering. The overall architecture of engineering, main flow of program and the main technical implementation means and results display, etc. According the simulation results with the actual situation, the results of simulation can be proved to be correct.

Keywords  rail transportation, vehicle braking resistor, traction power supply simulation, supply system
