  2. 1. Modelling and control of a line-commutated HVDC transmission system interacting with a VSC STATCOM

    Author : Paulo Fischer de Toledo; Hans-Peter Nee; Gustaf Ohlsson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Keywords : HVDC transmission; LCC – Line-commutated Current-source Converter; STATCOM; VSC – Voltage Source Converter; Space-Vector complex vector ; transfer-function; frequency-domain analysis; Electrical engineering; electronics and photonics; Elektroteknik; elektronik och fotonik;

    Abstract : The interaction of an HVDC converter with the connected power system is of complex nature. An accurate model of the converter is required to study these interactions. The use of analytical small-signal converter models provides useful insight and understanding of the interaction of the HVDC system and the connected system components. READ MORE

  4. 2. Simulation of vertical dynamic interaction between railway vehicle and slab track

    Author : Emil Aggestam; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; transition zones; genetic algorithm; dynamic vehicle–track interaction; Slab track; modelling; ballasteless track;

    Abstract : The usage of slab track for high-speed railway lines has increased in recent decades. In Sweden, the building of new railway lines for higher speed and the selection of track design for such lines are currently being debated. READ MORE

  5. 3. Train---Track Interaction. Coupling of Moving and Stationary Dynamic Systems: Theoretical and Experimental Analysis of Railway Structures Considering Wheel and Track Imperfections

    Author : Jens Nielsen; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : A general and well-structured method is advanced for analysis of the vertical dynamic interaction between a train and its track. The trains studied are modelled as linear or non-linear discrete mass-spring-damper systems. READ MORE
