  2. 6. 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. 7. The Effect of Crosslinking on Morphology and Electrical Properties in LDPE Intended for Power Cables

    Author : Susanne Nilsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LDPE; morphology; electrical treeing; peroxide; crosslinking; XLPE; water treeing;

    Abstract : Crosslinked polyethylene (XLPE) is used as underground cable insulation due to its outstanding electrical properties and high temperature dimension stability. XLPE is often made by peroxide initiated crosslinking of low density polyethylene (LDPE). The introduction of unsaturations, i.e. READ MORE

  5. 8. Reliability analysis and maintenance scheduling considering operating conditions

    Author : Dhananjay Kumar; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mining and Rock Engineering; Gruv- och Berganläggningsteknik;

    Abstract : In reliability analysis failure times are often considered as the only factor that can explain the reliability characteristics of a system. This may be insufficient. Operating conditions and other factors (e.g. READ MORE

  6. 9. The Effect of Crosslinking on Morphology and Water Treeing in LDPE

    Author : Susanne Nilsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; water treeing; peroxide; network structure; crosslinking; morphology; LDPE;

    Abstract : Crosslinked polyethylene (XLPE) is used as underground cable insulation due to its outstanding electrical properties and high temperature dimension stability. XLPE is made by peroxide initiated crosslinking of low density polyethylene. In recent years, polyethylene with unsaturations, i.e. READ MORE
