Analytical expression has been evaluated and instantaneous reactive power as a sign of exchange electrical energetic processes in the system of electric traction of direct current have been calculated. 

Introduction: With the introduction of high-speed traffic there is an increased consumption of traction current by new types of rolling stock. This issue is important, as high levels of traction currents can have not only prevents, but also a dangerous im... see more

Two ways of determining the spectral structure of random functions of the traction current and voltage on electric rolling stock current collectors are considered in the article. As an example, interharmonics of consumed current and voltage on the current... see more

The article considers issues of electromagnetic compatibility of traction network with the rail circuits. A mathematic model is elaborated for evaluation of distribution of harmonics of traction current on the length of feeder zone and determination of th... see more

The methods for determination of spectral composition of random functions of voltage and current of traction substation feeder are proposed. The low frequency components of their spectra (interharmonics) are obtained.

The article is a continuation of analysis of the electric equivalent AC circuit «traction substation - device of transversal compensation  - electric-traction network  - electric locomotive DS 3» and the influence on a power  transformer in... see more

The theoretical determination procedure of an equivalent loading current in tests of traction electric motors on heating without ventilation is offered. The results of calculation of an equivalent current for traction engine ED-118A are presented, as well... see more

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

On the basis of literature data analysis, an updated mathematical model has been developed, which describes electromagnetic processes in rail circuits during movements of electrified rolling stock. The model takes into account inductive influence of curre... see more
