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

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Linus Dahlgren; [2020]
    Keywords : ;

    Abstract : 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. READ MORE

  2. 2. Study of The Effect of Convective Heat Transfer on Cooling of Overhead Line Conductors Based on Wind Tunnel Experimental Results

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Wadih Naim; [2018]
    Keywords : heat balance; overhead conductor; convective cooling; dynamic line rating DLR ; värmebalans; luftledare; konvektiv kylning; dynamisk linjestorlek DLR ;

    Abstract : It is important to keep an overhead power line within rated operating conditions. Thus,an accurate prediction of the conductor's thermal and electrical behavior leads to an increasein reliability and eciency. Under DLR operation, the current rating is adjustedbased on ambient weather and solar conditions to allow for dynamic line loading. READ MORE

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

    University essay from Uppsala universitet/Industriell teknik

    Author : Marcelo Francisco Amaral; [2017]
    Keywords : ;

    Abstract : 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. READ MORE

  4. 4. Application of dynamic rating to improve transportation capability of the power systems connected to wind power plants

    University essay from KTH/Skolan för elektro- och systemteknik (EES)

    Author : Marco Merante; [2016]
    Keywords : dynamic line rating; overhead lines; conductor temperature model; wind energy;

    Abstract : Current flow in the electrical grid is changing due to the introduction of new generators and loads.Specifically, weak Overhead lines, are a constraint for the introduction of wind farms located farfrom the central network. The current situation requires smart solutions to improve the transportationcapabilities of these grid’s components. READ MORE

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

    University essay from KTH/Skolan för elektro- och systemteknik (EES)

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

    Abstract : 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. READ MORE
