  1. 1. System Stability of the Overhead Power Supply System used in the Electric Road System

    University essay from

    Author : Md Asif Ferdoush; [2019]
    Keywords : Electric Road System; eHighway; eMachine; Power Electronics; Overhead Catenary Line; Pantograph; Harmonics; Resonance;

    Abstract : This thesis presents the stability analysis of an Electric Road System (ERS), which is often abbreviated as eHighway, used for the electrification of the hybrid vehicle. The overall system modelling of the ERS, starting from the sub-station to the critical part of the Scania hybrid truck is performed in the MATLAB Simulink environment. READ MORE

  3. 2. Integrated analysis and design using graphic statics

    University essay from Lunds universitet/Byggnadsmekanik; Lunds universitet/Institutionen för byggvetenskaper

    Author : Erik Larsen; [2017]
    Keywords : Graphic statics; integrated design; sustainability; computational design; gaussian vault; catenary line; structural exploration; Technology and Engineering;

    Abstract : Numerical methods are the norm in modern structural engineering practice Models based on elasticity theory offer powerful methods to analyse complex structural behaviours and accurately predict probable deformation behaviour. Numerical methods in general and particularly finite element methods offer great numerical accuracy. READ MORE

  4. 3. Optimal Power Flow for an HVDC Feeder Solution for AC Railways

    University essay from KTH/Elektrisk energiomvandling

    Author : John Laury; [2012]
    Keywords : ;

    Abstract : With today’s increasing railway traffic, the demand for electrical power has increased. However, several railway systems are weak and are not being controlled optimally. Thus, transmission losses are high and the voltage can be significantly lower than the nominal level. READ MORE

  5. 4. Load flow control and optimization of Banverket’s 132 kV 16 2/3 Hz high voltage grid

    University essay from Institutionen för systemteknik

    Author : Annica Lindén; Anna Ågren; [2005]
    Keywords : 132 kV; rotary converter; load flow; power flow; feeding line; catenary; tap changer; control system; railway; electrification;

    Abstract : The purpose of this thesis was to investigate the possibility of power flow control, on a section of a railway grid fed by rotary converters, using an extra feeding line. Two possible solutions for the power flow control were examined. READ MORE
