  - ENERGIES - Rok 2022

  The development of electromobility involves the development of electric cars charging infrastructure. The increase of the number of chargers poses new demands for the AC power grid, especially in regard to its capacity of delivering high peak power. As an alternative for the public AC power grid, urban electrified transportation systems (trams, trolleybuses, and metro) can be used for supplying electric cars chargers. The article...

• Analytical modeling of electric drives for vehicle traction control systems

  Publikacja

  • A. Opaliński
  • L. Jarzębowicz

  - Rok 2016

  Wheel-torque control bandwidth in vehicle dynamics model is crucial in evaluating optimal tracking ability of tire slip and in analysis of control system stability. Electric drives’ control dynamics are influenced by timing of digital control events, e.g. by sampling instant of motor currents. Reflecting this timing in drive analytical models is therefore important for analysis of vehicle traction systems. The paper considers five...

• Water hammer analysis in water supply systems

  Publikacja

  • R. Wichowski

  - Rok 2008

  Przedstawiono metodę analizy zjawiska uderzenia hydraulicznego w sieci pierścieniowej. Model matematyczny opisano za pomocą układu równań różniczkowych cząstkowych I stopnia, które przekształcono do układu równań zwyczajnych. Dla rozwiązania układu równań zastosowano metodę predykator-korektor. Podano odpowiednie równania różnicowe dla węzłów złożonych. Przedstawiono przykład obliczeniowy sieci wodociągowej pierścieniowej, składającej...

• Use of numerical methods in the analysis of traction energy systems—an overview of the practical examples

  Publikacja

  • M. Bartłomiejczyk

  - Advances in Intelligent Systems and Computing - Rok 2016

  A characteristic feature of trolleybus transport is the random nature of traffic caused by congestion. It predestinates statistical and numerical methods for the analysis of trolleybus energy system. There are presented 3 methods of trolleybus traction system analysis: simulation of supply system based on Monte Carlo method, analysis of energy recovery potential based on statistical data analysis and benchmark of trolleybus supply...

  Publikacja

  • M. Bartłomiejczyk

  - Transport - Rok 2018

  Nowadays the issue of electric energy saving in public transport is becoming a key area of interest which is connected both with a growth in environmental awareness of the society and an increase in the prices of fuel and electricity. It can be achieved by improving the usage of regenerative breaking. In 2016 the Przedsiębiorstwo Komunikacji Trolejbusowej (PKT, Trolleybus Transport Company) in Gdynia began practical implementation...
