  1. 1. The Paradigm Shift for Substations Technology within Wind Power Applications from Onshore to Floating

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

    Författare :Ahmad Talaat Hifzy; [2023]
    Nyckelord :Floating; offshore; substation; transformer; GIS; equipment; high-voltage; fatigue; Flytande; havsbaserad; station; transformator; GIS; utrustning; högspänning; utmattning;

    Sammanfattning : Floating wind turbines are attracting more attention as more than three-quarters of the total offshore technical potential is located in deep water, leading to a growing trend in floating wind farm projects. Consequently, it becomes necessary to develop Floating Offshore Substation (FOSS) to step up voltage and efficiently transmit power to the shore with minimal losses. LÄS MER

  3. 2. Ray Tracing Algorithm for Dielectric Domes

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

    Författare :Maria Pubill; [2023]
    Nyckelord :Array antenna; dielectric dome; Ray-Tracing; reflection; absorption losses; matching layers; Arrayantenn; dielektrisk kupol; strålföljning; reflektion; absorptionsförluster; anpassningsskikt;

    Sammanfattning : Almost hemispherical scanning capabilities are required for modern wireless communication systems to produce broad coverage without performance degradation. Phased array antennas are commonly used as a fully-electronic beam-steering solution for its rapidity in beam switching. LÄS MER

  4. 3. Dielectric properties of ion-exchanged electrotechnical insulation papers : A study on the properties of novel papers

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

    Författare :Dan Selsmark; [2023]
    Nyckelord :Paper insulation; Frequency Domain Spectroscopy; Dielectric response; Karl Fischer titration; Dielectrics; Pappersisolering; Frekvensdomänsspektroskopi; Dielektrisk respons; Karl Fischer titrering; Dielektrika;

    Sammanfattning : Electrical insulation papers are a widely used group of papers in insulation applications and has been used for more than 100 years. Common applications include use as the dielectric medium in capacitors and insulation material in cables, bushings and transformers. LÄS MER

  5. 4. Birefringence: Effects and Implications on In-Ice Radio Detection of High-Energy Neutrinos

    Master-uppsats, Uppsala universitet/Högenergifysik

    Författare :Nils Heyer; [2022]
    Nyckelord :Birefringence; Cosmic Neutrinos; In-ice radio propagation;

    Sammanfattning : The detection of high-energy neutrinos in the EeV range requires new detection techniques to cope with the small expected flux. The radio detection method, utilizing Askaryan emission, can be used to detect these neutrinos in polar ice. LÄS MER

  7. 5. Scanning range extension by combining arrays with lenses

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

    Författare :Hairu Wang; [2022]
    Nyckelord :Dome Antenna; Dielectric Lens; Array Antenna; Kupolantenn; Dielektrisk lins; Array antenn;

    Sammanfattning : Array antennas, and more specifically phased array antennas, are widely used in radar detection and communication systems because of their excellent beam scanning ability and simple control. Generally speaking, the scanning function can be realized in two ways: mechanically or electronically. LÄS MER
