Planning of a rural network (English)
Abstract [en]

In this thesis a rural network in Norrbotten, Sweden, has been to designed and planned with the purpose of improving distribution reliability by exchanging existing overhead lines with underground cables. General network design considerations are discussed as well as the ones for the specific low voltage grid. During the design phase the maximum power of domestic consumers has been estimated using Velander’s method. Currents, voltage drop and impedance of the network have been calculated and fuse operation and selectivity has been considered. The network has been planned, parts lists have been compiled and an economical estimation of the project costs has been made. The project comprises of a local low voltage grid and high voltage cables and overhead lines. It has been concluded that with the suggested dimensioning and material, the network design criteria are met.
