    • Effect of placement of PMUs on state estimation in a power system 

      Mironov, Iurii (Master thesis; Mastergradsoppgave, 2016-11-07)
      State estimation is one of the most important processes in modelling and monitoring of a power system. Iterative and less accurate conventional means of estimation are now being replaced by fast and direct state vector measurements provided by PMUs. However, the high cost of PMUs forces engineers to choose wisely where the measurement units should be placed. The given project observes different ...

    • Thyristor based short circuit current injection in isolated grids 

      Hoff, Bjarte; Sharma, Pawan; Østrem, Trond (Peer reviewed; Bokkapittel; Chapter, 2017-02-16)
      This paper proposes a thyristor based short circuit current injector for providing short circuit current in isolated and weak grids, where sufficient fault current to trigger circuit breakers may not be available. This will allow the use of conventional miniature circuit breakers, which requires high fault current for instantaneous tripping. The method has been validated through experiments.
