  4. 3. Minimizing Transformer No-Load Losses at Hydropower Plants : A Study of Effects from Transformer Switch-Off During Stand-by Operation

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för elektroteknik

    Författare :Elin Luedtke; [2021]
    Nyckelord :step-up transformer; transformer switch-off; stand-by operation; idle operation; transformer winding; inrush current; fatigue stress; fatigue failure; S-N curve; transformer thermal cycling; thermal time constant; saving potential in hydropower; hydropower plant;

    Sammanfattning : Hydropower is the most important power balancing resource in the Swedish electrical power system, regulating the power supply to match the load. Consequently, several hydropower plants have periods of stand-by operation where the power production is absent but where several devices within a plant are still active. LÄS MER

  7. 5. Development of a Beam for a Vibration Motor

    Kandidat-uppsats, Högskolan i Skövde/Institutionen för ingenjörsvetenskap

    Författare :Kalle Nysell; Charlie Adam; [2021]
    Nyckelord :Finite element method; CAD; Inventor; mechanics; strength of materials; stress; development; design; Autodesk; Nastran; screen machine; material fatigue;

    Sammanfattning : This project is centered around the use of finite element analysis for developing a beam for a new type of motor used in a screening machine. Essentially the main purpose of the developed beam is to transfer vibrations to the screen machine that it will be attached to. LÄS MER
