Jämförelse av traktionssystem på Ostlänken - 15 kV 16 2/3 Hz och 25 kV 50 Hz
(2014)Programmes in Helesingborg
- Abstract
- In 2012 the Swedish government decided that Sweden’s first high speed rail shall be constructed. The railway is titled Ostlänken and forms a part of a potential high speed rail network. It also sets the technical standard for the new network, and therefore the possibility to improve technical solutions should be evaluated. The Swedish power supply system currently in use differs from the internationally more common system. This study aims to give partial insight regarding whether construction of the international traction power supply system on the specific high speed rail Ostlänken is to prefer. The results contain a summary of direct costs for electric energy, construction and maintenance for both traction power supply systems. The... (More)

This study aims to give partial insight regarding whether construction of the international traction power supply system on the specific high speed rail Ostlänken is to prefer. The results contain a summary of direct costs for electric energy, construction and maintenance for both traction power supply systems. The comparison has a special focus towards energy efficiency which has been studied by setting up simulations in Microsoft Excel. The internationally common system is more efficient regarding transmission, although the Swedish system overall is more energy efficient since it utilizes energy regenerated from braking rolling stock to a greater extent. Even though the Swedish system is cheaper regarding energy efficiency, the international system is slightly more economically beneficial when considering construction and maintenance costs as well. In conclusion, the direct economic benefit of building the international traction power supply system rather than the Swedish on Ostlänken is 40 MSEK over the railways lifespan of 60 years. The difference is in context marginal which along with uncertainty in calculations and regard to administrative cost of implementing a new system in Sweden leads to the recommendation of not using the international traction power supply system on Ostlänken.
