RESEARCH OF THE PARAMETERS OF ENERGY CONSUMPTION OF METRO TRAINS MODEL SIEMENS INSPIRO SF DURING ROAD TESTS

Georgi Dimitrov

The Sofia metro is the most important transport artery of public urban transport. In 2016 the construction of the third metro diameter (Line 3) of the metro in Sofia started, which is built with a completely new technology for traction power supply (overhead contact system with voltage 1500 VDC) and system for controlling the movement of metro trains (automatic, by wireless telecommunication). Line 3 of the metro will be serviced with new high-tech rolling stock - Siemens Inspiro SF metro trains, which are specially manufactured for the Sofia metro.

The study presents the results of a research on the energy consumption parameters of Siemens Inspiro SF metro trains during road tests on Line 3 of the Sofia Metro. The experimentally obtained data on energy consumption are analytically processed and presented in tabular form. Based on the obtained results, an analysis of the main energy indicators of Siemens Inspiro SF metro trains, realized in various road tests, was carried out, and specific conclusions were formulated.
