Published by Adam SZELĄG, Tadeusz MACIOŁEK, Politechnika Warszawska, Instytut Maszyn Elektrycznych Abstract. A 3 kV DC supply system, used on railways in Poland, since 1936, has power delivery capacity that allows reaching by trains a maximum speed of 250 km/h. Currently, the maximum trains service speed on Polish railway is 160 km/h, although speed recordContinue reading “A 3 kV DC Electric Traction System Modernisation for Increased Speed and Trains Power Demand – Problems of Analysis and Synthesis”

Electromagnetic Disturbances Propagation Along a Grounding Grid Subjected to Lightning Currents
Published by Rafael ALIPIO, Renan SEGANTINI, Federal Centre of Technological Education of Minas Gerais Abstract. This paper assesses the transient distribution of potentials along a grounding grid subjected to currents representative of first and subsequent strokes. It is shown that the transient non-uniform distribution of potential along the grounding system may lead to the flowContinue reading “Electromagnetic Disturbances Propagation Along a Grounding Grid Subjected to Lightning Currents”
Influence of Distributed Generation on Sectionalizing Switches Placement in MV Distribution Networks
Published by Wojciech BĄCHOREK1, Mariusz BENESZ1, AGH University of Science and Technology (1) Abstract. This paper presents the influence of distributed generation DG and reclosers placement on the reliability of distribution network. The brute force method and evolutionary algorithm were used to solve the optimization task. The placement of the switches was determined independently usingContinue reading “Influence of Distributed Generation on Sectionalizing Switches Placement in MV Distribution Networks”
The Influence of Power Supply Network Inductance on the HTS Transformer Inrush Current
Published by Grzegorz KOMARZYNIEC1, The Lublin University of Technology, Institute of Electrical Engineering and Electrotechnologies (1) Abstract. The HTS transformer inrush current may lead to thermal damage its windings made of HTS 2G tapes. The parameters affecting the value and duration of the inrush current are: the impedance of the transformer windings and the impedanceContinue reading “The Influence of Power Supply Network Inductance on the HTS Transformer Inrush Current”
