“…One of the most basic issues of electrical transport is its energy consumption and energy safety [1][2][3][4][5]. The issue of real value of the power supply voltage of traction units and electrical energy given back to the units are basic technical problems of DC traction power supply systems [6][7][8][9][10][11][12][13][14][18][19][20][21][22].…”

Urban and suburban public transport constitute basics of functioning of modern, urbanized metropolises. It is a comfortable, economic and ecological means of transportation. Thus, a stable and fast growth of this solution. One of its components is the power supply system. It should allow functioning of the whole transportation system, maintaining the following criteria: energy efficiency and modernity. These criteria have contributed to creation and modernization of power supply systems. Where it comes to DC systems, such an investment includes: replacing 6-pulse rectifiers with 12-pulse rectifiers and raising rated supply voltage. In this article, the authors have presented research results, based on measurements of electrical energy parameters before and after a modernization of a suburban transportation traction system. These parameters have been divided into two groups. The first consists of parameters mentioned in the EN50160 norm. Another group consists of parameters not mentioned in the norm. What has been presented are waveforms and graphs showing these parameters. In the final part of the article a discussion on reasonability of introducing new, modernized traction power supply system for suburban transportation has been performed.

The article discusses issues related to the variability of traction load and its impact on power losses in DC traction substations. Presented is the method of determining the influence of current averaging, which often happens in traction calculations. It has been shown that the averaging of the current has a significant impact on the inaccuracy of calculations or measurements of power and energy in DC traction power systems. The issues of variability of traction load are presented.

“…It also gives the possibility of using modern solutions in the field of traction power engineering, and in particular in the field of energy efficiency. These solutions contain, first of all, the recuperation of electricity and the use of energy storage tanks [5,6,7]. These methods are currently the basis in the field of energy consumption of rail vehicle traffic.…”

The railway traction network line is one of the technical elements ensuring proper operation of railway traffic. Due to its technical function and specificity, it is an essential element of the railway infrastructure. That is, why diagnostics of traction networks is a very important issue. In the article, the authors presented issues related to the diagnostics of 3kVDC traction networks. An analysis of traction network faults for a group of power supply areas was also presented. Additionally, calculations of damage indicators in a selected, representative power supply area are presented. On the basis of made an analysis authors proposed solutions aimed at minimizing breakdowns in traction networks.
