The problem of substantiation of developing complex distribution systems of electric power supply was considered as a hierarchy of problems at the first stage of which the problem of choosing a rational configuration of the power system was solved. A math... see more

A mathematical model of a local autonomous power supply source based on a diesel generator set is presented. The source of primary mechanical energy is a diesel internal combustion engine with an automatic speed controller, operating on the Polzunov–Watt’... 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 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 analysis of the basic components of electric power losses in elements of the power supply system is carried out and their classification is proposed.

The author proposed the examination method for estimating the reliability of functioning a system of automated control of traction electric supply systems for electric transport in order to organize the work with specialists-experts and to treat with expe... see more

The object of research is the power supply system of railway transport, which is part of a unified system and belongs to the class of geographically distributed electrical facilities. The main component of the system are electric networks, which represent... see more
