  1. 1. Transmission line protection performance in presence of power electronic-interfaced devices : Impact and needed countermeasures in the Swedish transmission system

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Elektricitetslära

    Författare :Hanna Olofsson; [2021]
    Nyckelord :;

    Sammanfattning : The penetration level of power electronic-interfaced devices (PEID:s) in power systems isincreasing, including wind- and solar power, HVDC and FACTS devices. Fault current injectedby PEID:s is lower in magnitude, may lack or contain a reduced negative sequence componentand can have a wide range of phase angles, as opposed to fault current supplied bysynchronous generators (SG:s).

    Sammanfattning : Museums have long had an important role as institutions for learning and education. In recent years, the pedagogical role of museums has become more important. Museums can offer a different kind of learning compared to the formal education system, and museums can be important resources for schools. LÄS MER

  4. 4. Utvärdering av ett byte till ACCC-högtemperaturlina på en 130 kV-ledning

    Master-uppsats,

    Författare :Sarah Kunz; [2021]
    Nyckelord :ACCC; HTLS; högtemperaturlina; PLS-CADD;

    Sammanfattning : This master thesis aims to investigate whether an installation of a High Temperature Low Sag-conductor (HTLS-conductor) could be beneficial for a 130 kV-transmission line owned by the Swedish company Vattenfall. The HTLS-conductors investigated in this thesis were ACCC-conductors and three different models were included: Warsaw, Dublin and Stockholm 3L ACCC-conductors. LÄS MER

  5. 5. Software development of visualizationsystem

    Kandidat-uppsats, Högskolan i Halmstad/Akademin för informationsteknologi; Högskolan i Halmstad/Akademin för informationsteknologi

    Författare :Fredrik Kortetjärvi; Rohullah Khorami; [2021]
    Nyckelord :;

    Sammanfattning : Today wireless technologies are increasing in the automation systems used in homes and buildings. More electrical devices are used in a house to save time, money, and energy because they are relatively inexpensive and easy to install; these devices even allow smart components such as mobile tablets and computer connectivity.
