In the article the expert management systems on the base of synthesis of heuristic and causal knowledge are offered that allows choosing the energy-saving modes and minimizing the power flow-overs and energy losses in electric-traction networks.

The paper carries out analysis of the influence of traction power supply system for double-track railway section with different kinds of traction on the work of rail circuits on the basis of developed mathematical model. The model takes into account induc... see more

The method of system approach for increasing the reliability of controlling equipment on traction electric supply system for electric transport is proposed. This approach is based on expert information that takes into account the importance of indices. Th... see more

The wide application and usage of electrical traction system presents utilities with planning andoperation challenges. Electric railways impose several power quality problems to the utility grid. Such as generatedlarge negative sequence components (NSCs),... see more

The research results specifying to the consumption of inactive (reactive by Fryze) power in a DC system of electric propulsion are stated in the article. It is shown that this consumption brings to considerable additional losses of electric energy in the ... see more

The existing methods of calculation of electromagnetic processes in the systems of traction AC power supply have been analyzed. The modern simulation methods for studying the electromagnetic processes have been proposed. The expression for calculation of ... see more

The object of research is the power regimes in traction power systems for both centralized and distributed power when introducing high-speed traffic. The introduction of high-speed traffic on electrified railways of Ukraine has begun a number of restricti... see more

A high-power reversible converter can achieve a variety of functions, such as recovering regenerative braking energy, expanding traction power capacity, and improving an alternating current (AC) grid power factor. A new hybrid traction power supply scheme... see more

Complete and accurate spatial magnetic field description is the premise of effectively assessing the power supply capability of a high-speed railway (HSR). Its evaluation indicators are the current distributions and the integrated impedance of traction ne... see more
