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 analysis of power indices of process of compensation of magnetic and mechanical losses in the charts of mutual loading of hauling electric motors with the use of electric power source is resulted.

The conditions of compensation of magnetic and mechanical losses during the test of hauling electric machines according to the Potier’s chart are considered.

In this work the generalized mathematical model of an electrical network of the electrified railway junction is proposed. An estimation of influence of static var compensators installation on electric power losses in a network is executed on the basis of ... see more

An indirect method of electric power losses determination in catenary has been examined. An example of solving such task with the help of specialized imitation model has been given and results of statistic analysis have been presented. Possible ways of us... see more

It is proposed to determine losses of electric power in transformers of a.c. tractive substations by statistical methods.

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 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
