Abstract [sv]

Hårdare krav ställs på leveranssäkerheten i de svenska elnätet. Kraven har ställts som följd av att flertal stormar och oväder har orsakat väldigt långa avbrott historiskt sett i Sverige. Det är nu olagligt att ha ett avbrott längre än 24 timmar. För att nå upp till kraven som ställs på leveranssäkerhet behöver nätföretag investera i sina befintliga nät. Generellt sett sker investering i att byta ut luftledning mot jordkabel.

Fortum äger en 12 kV-linje i ett område lokaliserat nordöst om Charlottenberg som är drabbad av avbrott och har hög genomsnittlig ålder. Ett mer tillförlitligt elnät måste upprättas.

I den här rapporten ges ett nätförslag som skulle leda till en förbättrad leveranssäkerhet och ökad tillförlitlighet.

Abstract [en]

Swedish legislation regarding network reliability has changed after the historic storm named Gudrun. It is now a violation to have interruptions in the distribution of electricity lasting longer than 24 hours. To reach needed reliability in the network, companies that distribute electricity need to invest in their existing grids. The general investment performed is exchanging overhead-lines to underground cables.

Fortum is the owner of a 12 kV rural power-line, located northeast of Charlottenberg, Sweden. This power-line has interruptions and an overall high age. A more reliable network has to be planned.

In this report, an alternative network is proposed, that would lead to improved reliability in the network.
