  1. 1. Modeling of temperature variations and response in a mining road bridge in Kiruna

    University essay from Lunds universitet/Avdelningen för Konstruktionsteknik

    Author : Mikael Fabricius; Henrik Ekman; [2016]
    Keywords : TEMPERATURE; CLIMATE; FINITE ELEMENT; DEFORMATIONS; KIRUNA; SMHI; BRIDGE; STRAINS; Technology and Engineering;

    Abstract : Den här studien har utförts på en bro i Kiruna, i norra Sverige, som användes till gruvindustrin. En modell av bron skapades med finita elementmetoden i programvaran Abaqus 6.14 för att ta reda på huruvida temperatur- och töjningsvariationerna på bron på grund av klimatets påverkan kan beskrivas.

  2. 2. Correction of Inhomogeneous Data in the Precipitation Time Series of Sweden Due to the Wind Shield Introduction

    University essay from Uppsala universitet/Luft-, vatten och landskapslära

    Author : Ioannis Sofokleous; [2016]
    Keywords : Precipitation data correction; precipitation time series; homogenization of precipitation data; wind shield; wind screen; aerodynamic wind error; Nederbördsdatakorrektion; nederbörds tidsserier; inhomogena nederbördsdata; vindskydd; vindskärm; aerodynamiska vindfel;

    Abstract : The work of this master thesis is based on analyses of monthly precipitation data from 70 stations of the SMHI (Swedish Meteorological and Hydrological Institute) in Sweden, in the period 1860-2014, using the information for the year of introduction of the wind shield at each station. The primary goal is the calculation of correction factors which will be applied on the precipitation data in the period of measurements before the introduction of the wind shield. READ MORE

  3. 3. The potential for centralized photovoltaicsystems in Sweden

    University essay from KTH/Hållbarhet och industriell dynamik; KTH/Hållbarhet och industriell dynamik

    Author : REBECCA KARLSSON; EVA NILSENG; [2016]
    Keywords : Grid-connected centralized PV systems; profitability PV farms; PV industry; large scale production; PV in Sweden; key factors; main challenges.;

    Abstract : Considering the long term target set by the Swedish government of having an energy system basedexclusively on renewable sources, the potential for different renewable sources need to beinvestigated. When analyzing the sources used for electricity production in Sweden today, solarPV represents a very small share. READ MORE

  4. 4. Application of dynamic rating to improve transportation capability of the power systems connected to wind power plants

    University essay from KTH/Skolan för elektro- och systemteknik (EES)

    Author : Marco Merante; [2016]
    Keywords : dynamic line rating; overhead lines; conductor temperature model; wind energy;

    Abstract : Current flow in the electrical grid is changing due to the introduction of new generators and loads.Specifically, weak Overhead lines, are a constraint for the introduction of wind farms located farfrom the central network. The current situation requires smart solutions to improve the transportationcapabilities of these grid’s components. READ MORE

  5. 5. Calculation of Environmental Profits with Weight Reduced Core Material in Rotor Blades

    University essay from Lunds universitet/Mekanik

    Author : Anita Tran; [2016]
    Keywords : Earth and Environmental Sciences; Mathematics and Statistics;

    Abstract : Construction of wind turbines has increased these recent years and is expected to escalate more in the nearest future. The expansion of wind power as an energy source requires specific and comprehensive transport, when production is far away from the installation site. READ MORE
