  1. 1. Studie över klimatförändringars påverkan på dynamisk ledningskapacitet

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Elektricitetslära

    Författare :Linnea Hahne; [2021]
    Nyckelord :climate change; dynamic line rating; static line rating; line rating; ampacity; overhead line; distribution line; transmission line; conductor; thermal capacity; real-time monitoring; klimatförändringar; dynamisk ledningskapacitet; statisk ledningskapacitet; ledningskapacitet; ampacitet; luftledning; distributionsnät; transmissionsnät; ledare; termisk kapacitet; realtidsmätning;

    Sammanfattning : The thesis aims to examine the impact of climate change on line rating and to investigate the possibility of a potential increase of capacity of an overhead line. The line rating of an overhead line determines how much current can be transmitted in the line. LÄS MER

  3. 2. Case Study on Applications of Measurement Equipment for Dynamic Line Rating

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

    Författare :Linus Dahlgren; [2020]
    Nyckelord :;

    Sammanfattning : Dynamic Line Rating is the concept of rating the ampacity of power lines depending on the thermodynamicconditions of the lines. It is an alternative to Static Line Ratings, which are set to maintainnetwork safety requirements under unfavourable operating conditions. LÄS MER

  4. 3. Integration of Dynamic Line Rating within a Risk-Based Security Assessment Framework

    Master-uppsats, Uppsala universitet/Industriell teknik

    Författare :Marcelo Francisco Amaral; [2017]
    Nyckelord :;

    Sammanfattning : The following work applies Dynamic Line Rating (DLR) to a Risk-Based SecurityAssessment (RBSA) methodology with the ultimate goal to perform day-aheadforecastanalysis. DLR quantifies transmission capacities of overhead lines whilst beingdependent on ambient conditions. LÄS MER

  5. 4. Development of an automatic autonomous sensor carrier for sound profile measurement in deep sea

    Master-uppsats, KTH/Marina system

    Författare :Niklas Möller; [2016]
    Nyckelord :;

    Sammanfattning : This Master Thesis main purpose was to answer the question "Can you measure or calculate the velocity sound profile while performing a bathrymetric survey in an offshore environment like the North Sea, without any interaction nor modification of the existing equipment?".This, since today underwater surveys are a complex and expensive operation to perform where you either are mapping the sea floor or on a searching mission for a sunken wrecks.

  7. 5. Building predictive models for dynamic line rating using data science techniques

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

    Författare :Nicolae Doban; [2016]
    Nyckelord :Dynamic Line Rating; Data Science; Exploratory Data Analysis; Predictive Modeling; Energy Efficiency; Renewable Energy Sources; Power system planning and operations; Reproducible;

    Sammanfattning : The traditional power systems are statically rated and sometimes renewable energy sources (RES) are curtailed in order not to exceed this static rating. The RES are curtailed because of their intermittent character and therefore, it is difficult to predict their output at specific time periods throughout the day. LÄS MER
