  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. Nätnyttoersättningens utformning : En fallstudie på elnätsbolaget E.ON Energidistribution

    Master-uppsats,

    Författare :Moa Laredius; Petra Wennberg; [2019]
    Nyckelord :Business Model; Business Model Canvas; Stakeholder Theory; Triple Bottom Line; Legitimacy Theory; Affärsmodell; Business Model Canvas; Intressentmodellen; Triple Bottom Line; Legitimitetsteorin;

    Sammanfattning : In today’s society it is more common for industries to automate their businesses and more people are in need of electricity. Therefore, a stable and reliable supply of electricity is needed. When more people need electricity, it affects the liability of the powerlines which leads to more losses. LÄS MER

    Sammanfattning : The purpose of this study is to investigate and analyze stops that occur in the painting process of trucks; specifically related to the buffer system after the top coat process. Based on this investigation, improvements are presented in order to eliminate stops and improve overall assembly time. LÄS MER

  5. 4. Ergonomic Evaluation of Power Tool Use at Different Task and Tool Related Conditions Using a Mechanical Test Rig, Electromyography and Subjective Evaluations

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Ava Mazaheri; [2018]
    Nyckelord :Power Tools; Tightening Tools; Ergonomics; Subjective Ratings; Torque Tools;

    Sammanfattning : Workers within production and assembly lines are often exposed to ergonomically unfavorable tasksand conditions. Reaction forces and reaction torques generated by industrial power tools may causenot only discomfort but also health issues and injury. LÄS MER

  7. 5. Power Electronic Stages for a TFPMSM in Wave Power Applications

    Master-uppsats, KTH/Skolan för elektro- och systemteknik (EES)

    Författare :Gustaf Falk Olson; [2016]
    Nyckelord :transverse flux permanent magnet synchronous machine TFPMSM ; active rectifier; direct drive wave energy converter; feedback linearization; cascaded PID controller.;

    Sammanfattning : Direct drive wave energy conversion systems have been identified as a potentially major contributor to the world’s energy demands, forecasting shares of up to 25 % of the energy mix. Anders Hagnestål conducts research at the Royal Institute of Technology where a novel linear transverse flux permanent magnet generator is developed. LÄS MER
