Abstract [en]

Karlstads Elnät is a company that manages their operation within the municipality of Karlstad. The company’s main objective is to deliver power requirements to the consumer in a reliable way. Due to a variety of past economic factors the grid has become unnecessarily over-dimensioned. The study therefore discusses strategies on how power distribution grid companies can optimize their grid projection plans.

The project is based on studies that have been implemented in the simulation program Facilplus Spatial. This study resulted in thorough investigations of four alternative grid projection plans. The authors have selected transformer station T344, Karlagatan 13 as the limitation for the task. A number of models of distribution grids have been compared with the company’s grid design through computing the programs performance. The computing proved, for example, the importance of correct location of the transformer station as well as the importance of appropriate cable dimensions in an economic perspective. These findings reveal the significance of continuous computation of the power distribution grids.

Throughout the project the authors have found some problems with the existing distribution grid area. Among other things the use of the transformer today is 96 % of the works output. This indicates that future increases of the power load or extended constructions are not possible without adjustments. The authors have therefore offered recommendation to the company to solve these problems.

This report is written in Swedish.
