  1. 6. Tribological characterization of a ball bearing subjected to an electric field : Electric drivetrain tribology

    Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Muhammad Umar Farooq; [2023]
    Nyckelord :Ball bearing; electric drivetrain; tribology; electric field; characterization; bearing currents; discharge;

    Sammanfattning : Electric machines are widely used in for instance the automotive industry in electric vehicles and in wind turbines. The electrical machines have mechanical bearings as an integral part used to transmit power and load. In addition, the main function includes reducing friction between interacting surfaces. LÄS MER

  3. 7. Colliding interests: Examining Sami rights amidst the green transition - A comparative study of the Norwegian and Swedish Sami communities’ power in wind turbine licensing

    Kandidat-uppsats, Lunds universitet/Statsvetenskapliga institutionen

    Författare :Linn Lyckdal; Karin Ehn Magnusson; [2023]
    Nyckelord :Green transition; Indigenous rights; Norway; Power; Robert Dahl; Sami community; Sweden; Wind power.; Law and Political Science;

    Sammanfattning : This thesis is a comparative case study of the Norwegian and Swedish Sami communities' power in the licensing process for wind turbines on their land. The study aims to identify the Norwegian and Swedish Sami communities' power and whether it differs between the two countries. LÄS MER

  4. 8. Vindkraft i relation till andra intressen om mark : Elbehov i Norrbottens län

    Kandidat-uppsats, Umeå universitet/Institutionen för geografi

    Författare :Henrik Näsholm; [2023]
    Nyckelord :Electricity shortage; Norrbotten län; conflicting interests; human interests and economic interests.;

    Sammanfattning : The electricity demand in Norrbotten County is expected to increase from 8 TWh in 2019 to 107 TWh in 2050. A contributing role to the large electricity demand in Norrbotten County is that LKAB will make large investments within the company. LKAB's electricity needs will increase from 2 TWh in 2020 to 50 TWh in 2040. LÄS MER

  5. 9. Facilitating locations of green energy on land. What can make it successful? - A case study of the Energy Park Veddum Kær

    Master-uppsats, Lunds universitet/Institutionen för kulturgeografi och ekonomisk geografi

    Författare :Karl Felix Flyvbjerg Poulsen; [2023]
    Nyckelord :green energy transformation; Wind turbines; solar panels; case study; path-dependance; successful location; Social Sciences;

    Sammanfattning : This paper investigates what can promote green energy projects on land which consist of solar and wind power. The research is done with an economic geographic framework of path-development. A paradigmatic case study is conducted with scientific semi-structured interviews and short “pop-up interviews” which validated the in-depth interviews. LÄS MER

  7. 10. Framtagning av testrigg för att testa regnerosion på vindturbinblad

    Kandidat-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Nils Arvidsson Lindbäck; David Johansson; [2023]
    Nyckelord :leading edge erosion; test rig; wind turbine blades; wind power; kanterosion; testrigg; turbinblad; vindkraftverk;

    Sammanfattning : Bakgrunden till projektet är problem med kanterosion av turbinblad inom vindkraftverks- industrin. Det är ett fenomen som uppstår när turbinblad roterar i höga hastigheter och träffar partiklar, främst vattendroppar i regn. LÄS MER
