Estimation of specific traction electric power consumption for Bogotá Metro First Line

This study aims to identify the mechanical variables that exert the greatest influence on the consumption of traction energy in a metro-type system, estimate specific energy consumption in different operating scenarios associated with speed profiles in each section and establish specific reference consumptions that guide the identification of projects aimed at increasing energy efficiency, all estimated for when the first line of the Bogota Metro comes into operation. To achieve the previous objectives, this research was focused on the estimation, through a software application, of the specific consumption of electrical energy of the Metro System of the City of Bogota, for different operating scenarios. Results of simulations carried out with an application developed in Matlab, to generate speed profiles in the operation of the train, allow observing the sensitivity of the specific consumption of electrical energy in the face of changes made in the cruise speed and in the acceleration ramps and slowdown. The results show that the specific consumptions depends to a great extent, on the speed profiles, and consequently on the operation of the system, which opens an interesting field of application of optimization techniques oriented to the efficient use of energy in the future operation of the system.
