Abstract
Power supply is a social necessity, and will so continue to be in the near future. Therefore, safe and steady deliverance of power supply is a fundamental duty of the societies and the preparedness of the vulnerability of the infrastructures is highly prioritized.

The power supply comprises every component needed for transmission of electrical power from generation to consumption, power transformers are key components of this network, transforming electrical power to customized levels.

Power supply is a social necessity, and will so continue to be in the near future. Therefore, safe and steady deliverance of power supply is a fundamental duty of the societies and the preparedness of the vulnerability of the infrastructures is highly prioritized.

The power supply comprises every component needed for transmission of electrical power from generation to consumption, power transformers are key components of this network, transforming electrical power to customized levels.

The aim of this master thesis was to present methods on how to improve the establishment of power transformers. More specifically, the scope of the aim was to improve the timeframe for the exchange of transformers by simplifying and improving the aspect of route planning, and thereby to generate improved transformer preparedness. This was done using Geographical Information Systems, involving the building of a multimodal network dataset and performing route calculations. The location of the study was set to southern Norway and the distance between the connector stations Sylling and Stølen. The analysis was based on information
about the sea ways, landfalls, electronic road network, height, road block, weight, speed and distance. A method for effective route planning was developed and the distance Sylling-Stølen was used in a case study, where modeled and actual transport routines were compared.

The results show a difference between the actual and the modeled routes, both on duration and path, mainly due to a low focus on bridges and to inaccurate data. The overall difference in time was minor, the modeled route diverging only one hour from the actual, the difference on specific stretches were however greater, either witnessing of potential of faster transport or data which has not been adapted close enough to the actual situation.

Abstract (Norwegian)
Strømforsyning er et nødvendig gode for dagens samfunn og vil være det i fremtiden. Å sikre en trygg og stabil leveranse av strøm er en grunnleggende oppgave for samfunnet, beredskapen av den kritiske infrastruktur må derfor være høyt prioritert.

Strømforsyningen omfatter alle komponenter som er nødvendige for overføring av elektrisitet fra produsent til forbruker. Transformatorer er sentrale komponenter i strømnettet og har som oppgave å transformere strømmen til et brukertilpasset nivå.

Målet for denne masteroppgaven har vært å utvikle metoder som forbedrer prosessen rundt transformator bytte. Nærmere bestemt så har oppgaven sett på om det er mulig å redusere tiden på et transformatorbytte, ved å forenkle og utvikle... (More)
Strømforsyning er et nødvendig gode for dagens samfunn og vil være det i fremtiden. Å sikre en trygg og stabil leveranse av strøm er en grunnleggende oppgave for samfunnet, beredskapen av den kritiske infrastruktur må derfor være høyt prioritert.

Strømforsyningen omfatter alle komponenter som er nødvendige for overføring av elektrisitet fra produsent til forbruker. Transformatorer er sentrale komponenter i strømnettet og har som oppgave å transformere strømmen til et brukertilpasset nivå.

Målet for denne masteroppgaven har vært å utvikle metoder som forbedrer prosessen rundt transformator bytte. Nærmere bestemt så har oppgaven sett på om det er mulig å redusere tiden på et transformatorbytte, ved å forenkle og utvikle ruteplanlegging. Det er et håp å generere bedre beredskap av transformatorer på denne måten. I oppgaven har det vært bygget multimodale nettverks datasett og utført rute beregninger i Geografiske informasjonssystemer.
Studieområdet har omfattet Sør-Norge, nærmere bestemt strekningen mellom Sylling og Stølen. Analysen har vært basert på data om farleder, landingsplasser, elektronisk vegnett, høyde-, vekt- og farts restriksjoner, veg sperringer og ikke minst avstander. Det ble i løpet av
prosjektet utviklet en metode for effektiv ruteplanlegging hvor strekningen Sylling - Stølen ble brukt som utgangspunkt. Resultatene fra den modellerte og den faktiske ruten ble til slutt sammenliknet.

Resultatene viser en differanse mellom den faktiske og den modellerte ruten, både i forhold til
tidsbruk og veivalg, først og fremst grunnet et for lavt fokus på bro-attributtene og unøyaktige data. Den overordnede forskjellen i tid var liten, faktisk bare en time, differansen mellom mer spesifikke strekninger derimot var større. Resultatet beskriver at det enten er mulig å redusere den virkelige tidsbruken, eller at dataene ikke har vært tilpasset virkeligheten godt nok. (Less)
