Development of scientific principles reduction in energy losses in the traction DC network by controlling traffic flows

摘要

Introduction: Ukraine belongs to the energy deficient country that meets the needs for fuel and energy resources by own production at a level less than 50%. Since the energy component of the cost of transportation is about 20%, energy efficiency is one of the main policy objectives of Ukrzaliznitsa. Reduction of energy losses in traction lines is one of the main energy savings methods on electrified lines. The purpose of this paper is to develop scientific principles of reducing power losses in traction lines by selecting the optimal deployment of trains between traction substations, the optimal sequence of trains and the intervals between trains. Methods: we used the method of deformed polyhedron, heuristic algorithms, statistical treatment of experimental data. Scientific novelty: it’s proposed the scientific principles for reduction of energy losses in traction lines by optimal deployment of trains in the area, due to the selection of the optimal interval at the site on the basis of the deformed polyhedron due to the choice of the optimal sequence of trains departure. Practical significance: The scientific principles of reducing energy losses in traction lines can be used for the planning of energy saving measures in power supply systems.
