  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. Energy retrofit of an office building in Stockholm: energy performance analysis of the cooling system

    University essay from KTH/Installations- och energisystem

    Author : Pierpaolo Maggiore; [2016]
    Keywords : building retrofit; building performance; energy performance analysis; energy audit; ida ice; dynamic simulation;

    Abstract : The increasing attention towards energy efficiency issues has triggered an important process involving the renovation of existing buildings and, at the same time, the creation of recognized certifications assuring the quality of the projects. In line with this trend, the Sweco headquarters, an office building characterized by 24700 m2 of floor area and located in Stockholm, was totally retrofitted in 2012 and obtained the Gold rating after being assessed with the Miljöbyggnad certification procedure.
