Document Type : Scientific - Research

Abstract

In this article the principle and framework for software design and simulation of traction power supply in urban railway projects are described. The main aim of this design will be creating proper tools and methodology to determine the places of rectifier substations, rectifier unit capacity, choosing of feeder cables and cross dimension n of conductors in traction network and also confirming the capacity of transformers in high voltage posts. Meanwhile an equivalent model for requested network is presented and the equations of network are found.  In the model and equations which have large scale and quantities of variables, the optimization numerical method such as Doglag are applied to guarantee the convergence accelerate the speed of solution. The article considers the standards like CEI EN 5032, IEC 146, EN60146 and CEI EN 50329 to ensure the results of obtained model and equations. To verify the credit of presented solution, the line 4 of Tehran metro have been simulated and compared.
