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. Review and Design of DC Electrical Field Measurement Systems and Related Developments : For Measurements Around HVDC Cable Terminations

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

   Författare :Emil Bergvall; [2023]
   Nyckelord :DC Field Probe; Measurement Systems; Electric Fields; Cable Termination; Ion Drift; Conductivity; HVDC; Field Mill; Field Simulations; Positioning System; MEMS; Electro-Optics; DC Fält Prob; Mätsystem; Elektriska Fält; Kabelavslut; Jondrift; Ledningsförmåga; HVDC; Fältkvarn; Fält Simulationer; Positioneringsystem; MEMS; Elektro-Optik;

   Sammanfattning : With power generation and consumption placed further away from each other, with for example increased offshore power production, the need for HVDC transmission systems increases. As voltage levels in the HVDC transmission system are raised, the losses can be decreased, enabling efficient power transfer over longer distances. LÄS MER

4. 3. Energy harvesting för sensorer i tung industriell miljö

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

   Författare :Elias Tångås; [2023]
   Nyckelord :;

   Sammanfattning : Energy harvesting essentially involves extracting energy from processes that generate losses in theform of heat, vibrations, radiation, etc, and converting it into electrical energy that can be used topower sensors or other electrical systems. A customer of Knightec Örnsköldsvik wants to develop measurement equipment using sensors in a demanding industrial environment with rotating machines that does not allow wired energy or communication transfer.

5. 4. Förlustanalys av Elnätdistribution i Eskilstuna : En noggrann undersökning av elförluster och dess konsekvenser i ett område i Eskilstuna

   Uppsats för yrkesexamina på grundnivå, Mälardalens universitet/Akademin för ekonomi, samhälle och teknik

   Författare :Omid Hosseani; Touma George; [2023]
   Nyckelord :Transmission losses; Distribution losses; Line losses; Power losses; Energy losses; Joule losses; I2R losses; Electrical losses; Technical losses; Non-technical losses; T D losses Transmission and Distribution losses .; Effektförluster; Energiförluster; Jouleförluster; I2R förluster; Elektriska förluster; Tekniska förluster; Icke-tekniska förluster; T D förluster Transmission och distributionsförluster ;

   Sammanfattning : This thesis explores the losses occurring in a specific region located in the southern part of Eskilstuna, where ESEM serves as the network owner. The study places particular emphasis on power factor and load factor as key factors. Its objective is to analyze and comprehend the extent of losses in the network and their implications. LÄS MER

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