  1. 1. Stability of power systems with large amounts of distributed generation

    University dissertation from Stockholm : Elektrotekniska system

    Author : Valerijs Knazkins; KTH.; [2004]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical engineering; engineering; electronics and electrical engineering; system science; Elektroteknik; TECHNOLOGY Electrical engineering; electronics and photonics Electrical engineering; TEKNIKVETENSKAP Elektroteknik; elektronik och fotonik Elektroteknik;

    Abstract : This four-part dissertation is essentially concerned with some theoretical aspects of the stability studies of power systems with large penetration levels of distributed generation. In particular, in Parts I and II the main emphasis is placed upon the transient rotor angle and voltage stability. READ MORE

  5. 5. A new Auxiliary Converter Topology with SiC Components for Railway Applications

    University dissertation from Stockholm : KTH

    Author : LUYU WANG; Lund University.; Lunds universitet.; [2016-06-08]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Auxiliary converter; Multilevel converter; ; Silicon Carbide transistors;

    Abstract : Smaller size and lower weight are always the targets of the power electronic product development. This work introduces two new topologies of auxiliary converters which have the feature of fewer components and fewer number of energy conversion stages comparing with the conventional auxiliary converter used in railway applications.
