  2. 1. Multi-terminal HVDC protections based on transient line modeling

    Author : Niclas Johannesson; Staffan Norrga; Hans-Peter Nee; Jef Berteen; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HVDC transmission; HVDC protection; traveling wave protection; MTDC protection; Electrical Engineering; Elektro- och systemteknik;

    Abstract : High voltage direct current (HVDC) is considered one of the critical technologies required for the power system to enable the transition toward renewables. With an increasing geographical density of HVDC converters, there is a potential for optimization by connecting more than two converters into a shared DC transmission system, thus forming a multi-terminal HVDC (MTDC) system.

  4. 2. Physical effects of nonlinearity in discrete onedimensional systems with spatial variations

    Author : Erik Lennholm; Luis Mario Floria; Linköpings universitet; []
    Keywords : ;

    Abstract : Physical properties of a solid are affected, to a very high degree, by the spatial structure of the material at hand. This thesis is concerned with such effects in nonlinear systems. In itself, nonlinearity is a subject on the move, and more and more areas of physics tend to take nonlinear effects into account. READ MORE
