  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. Innovative active control strategies for pantograph catenary interaction

    University essay from KTH/Fordonsdynamik

    Author : Roberto Tieri; [2012]
    Keywords : Active control; pantograph catenary interaction; actuator;

    Abstract : The pantograph - catenary interaction is one of the most important features in high speed trains, and to guarantee a reliable current collection is the target that every railway system must take into consideration in order to speed up trains. The problem that goes against this direction is mainly the variation of the overhead equipment's stiness. READ MORE
