Assessment of Energy Intensity of the Drive for Traction Power Supply System

Abstract

The article discusses questions about using the electric energy storage units in the DC electric traction system. As placements of the electric energy storage units, there were chosen the posts of sectionalization on the areas of the electric rolling stock’s maintenance using the regenerative braking in the conditions of the way’s mountain profile. In the research, there was used a method of simulation modeling of the interaction between the electric rolling stock and the electric traction system on the example of one of the Transsiberian railway’s areas. There were given the results of the statistical processing of the received graphs of the change of the storage units’ voltage and workload. There was shown the influence of the electric energy storage units to the main energy parameters of the electric traction system’s work. There were received the frequency distributions for the electric energy volumes, the duration of the episodes of the storage unit’s work, the assessment of the energy intensity in the modes of charge and discharge, there was done the assessment of the energy intensity, the capacity and the electric energy storage unit’s operation time. Based on the data obtained, there were considered the basic provisions of the methodology for determining of the electric energy storage unit’s capacity and energy intensity in the electric traction system subject to the cyclicity of work, the conditions for the regimes change of the charge and discharge, the energy intensity’s effective usage, and the interaction variants in the information system of the energy parameters’ monitoring.
