  • System Energy Optimisation Strategies for DC Railway Traction Power Networks By
    System Energy Optimisation Strategies for DC Railway Traction Power Networks by Zhongbei Tian A thesis submitted to the University of Birmingham for the degree of DOCTOR OF PHILOSOPHY Department of Electronic, Electrical and Systems Engineering College of Engineering and Physical Sciences University of Birmingham, UK June 2017 University of Birmingham Research Archive e-theses repository This unpublished thesis/dissertation is copyright of the author and/or third parties.

Abstract Abstract As a result of rapid global urbanisation, energy and environmental sustainability are becoming increasingly significant. According to the Rail Transport and Environment Report published by International Union of Railways in 2015, energy used in the transportation sector accounts for approximately 32% of final energy consumption in the EU. Railway, representing over 8.5% of the total traffic in volume, shares less than 2% of the transport energy consumption. Railway plays an important role in reducing energy usage and CO2 emissions, compared with other transport modes such as road transport. However, despite the inherent efficiency, the energy used by the rail industry is still high, making the study of railway energy efficiency of global importance. Previous studies have investigated train driving strategies for traction energy saving.

  • An Influence of a Complex Modernization of the DC Traction Power Supply on the Parameters of an Electric Power System
    MATEC Web of Conferences 180, 02001 (2018) https://doi.org/10.1051/matecconf/201818002001 MET’2017 An influence of a complex modernization of the DC traction power supply on the parameters of an electric power system Jerzy Wojciechowski1,*, Krzysztof Lorek2, and Waldemar Nowakowski1 1Kazimierz Pulaski University of Technology and Humanities in Radom, ul. Malczewskiego 29, 26-600, Radom, Poland 2Sonel S.A., ul. Wokulskiego 11, 58-100, Świdnica, Poland Abstract. 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. 1 Introduction and electrical energy given back to the units are basic technical problems of DC traction power supply systems The issue of energy efficiency in the traction power [6-14, 18-22].
