  1. 1. Competitor analysis of the synchronous machines market : A study of how manufacturers differentiate themselves from each other with unique value propositions

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Fredrick Fager; Jiyan Kösanlioglu; [2023]
    Nyckelord :Synchronous machines; synchronous motors; synchronous generators; competitor analysis; value proposition; Synkronmaskiner; synkrona motorer; synkrona generatorer; konkurrentanalys; värdeerbjudande;

    Sammanfattning : This report highlights the market for synchronous machines and examines the current situation. Today, the world demands higher volumes of electrical power that is cleaner, more efficient and generated from fossil-free sources. This increases the importance of using efficient and modern that minimise energy losses. LÄS MER

  5. 4. 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

  7. 5. Analys och minskning av effektförlusterna i en borstlös likströmsmotor med vektorstyrning

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Industriell elektroteknik och automation

    Författare :Lider Xavier Garcia Parrales; [2023]
    Nyckelord :Effektförluster Borstlös likströmsmotor BLDC Vectorstyrning Field-oriented Control FOC Blockkommutering Block commutation MTPA; Technology and Engineering;

    Sammanfattning : This report addresses power losses in an electric motor arising from various sources. The choice of motor control strategy can decrease efficiency if not implemented correctly or if the motor model in the control loop is overly simplified. LÄS MER
