  1. 1. Single- or Three-Phase Supply to Homes : Advantages and Disadvantages compared between Single-phase and Three-phase domestic electricity

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Alexander Grönblad; [2022]
    Nyckelord :Elecricity Tariff; Single-phase Supply; Three-phase Supply; Load Curve; Homes; Eltariff; Enfasmatning; Trefasmatning; Lastprofil; Bostäder;

    Sammanfattning : A three-phase power supply is a de facto standard when selecting a power supply to homes in Sweden, regardless of whether it is flat with low energy consumption or a house with electric heating. This project aims to determine the advantages and disadvantages of using a three-phase supply compared to a single-phase supply to homes. LÄS MER

  3. 2. Grid integrated PV systems in Germany

    M1-uppsats,

    Författare :Karin Schrewelius; Filloreta Rexhepi; [2015]
    Nyckelord :Single phase PV systems; Grid integrated PV systems; Battery storage technology;

    Sammanfattning : The environmental awareness has led to many political decisions and initiated laws that regulate the market towards responsible energy usage. The demand of sustainable power has led to an increasing integration of renewable energy sources to the electric grid. Solar power is the 3rd largest renewable power source after wind and bio-power.

  5. 4. Hur påverkar en ökad andel solceller Umeå Energis elnät? : – En utredning med fokus på spänningsvariationer och osymmetri inom landsbygds- och tätortsnät vid en- och trefasanslutning av solcellsanläggningar

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Författare :Linn Larsdotter; [2014]
    Nyckelord :Solceller; växelriktare; enfas; trefas; spänningsvariationer; osymmetri; elkvalitet;

    Sammanfattning : A good power quality can be an important prerequisite to achieve a sustainable society. Scandinavia's electrical system is in many respects superior, and Sweden has a fossil free electricity generation at 97 % and a reliability of electricity distribution at 99.98 %. LÄS MER

  7. 5. Single phase laminar convective heat transfer of nanofluids in a micro-tube

    Master-uppsats, KTH/Energiteknik

    Författare :Itziar Lumbreras Basagoiti; [2011]
    Nyckelord :Nanofluids; convective; micro-tube; laminar;

    Sammanfattning : Nanofluids are homogeneous mixture of dispersed solid particles in base fluids. These solid particles are usually smaller than 100nm. Suspended nanoparticles modify the properties of based fluids. It is claimed, in some literature, for nanofluids to have greater than expected heat transfer performance. LÄS MER
