  1. 1. Single- or Three-Phase Supply to Homes : Advantages and Disadvantages compared between Single-phase and Three-phase domestic electricity

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

    Author : Alexander Grönblad; [2022]
    Keywords : Elecricity Tariff; Single-phase Supply; Three-phase Supply; Load Curve; Homes; Eltariff; Enfasmatning; Trefasmatning; Lastprofil; Bostäder;

    Abstract : A three-phase power supply is a de facto standard when selecting a power supply to homes in Sweden, regardless of whether it is flat with low energy consumption or a house with electric heating. This project aims to determine the advantages and disadvantages of using a three-phase supply compared to a single-phase supply to homes. READ MORE

  3. 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

  4. 3. 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. 4. Feeder Dynamic Rating Application for Active Distribution Networks using Synchrophasors

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

    Author : Narender Singh; [2016]
    Keywords : Ampacity; Dynamic line rating; IEEE 738-2006; Kalman filter; LabVIEW; Line loading; Opal-RT; PMU; State change equation;

    Abstract : There is an ever increasing demand of electricity and to meet this demand, installation of new transmission and distribution lines is required. This task requires a significant investment and consent from the respective authorities. An alternative is to utilize maximum capability of the existing lines. READ MORE

  6. 5. Dynamic Line Rating - Thermal Line Model and Control

    University essay from Lunds universitet/Industriell elektroteknik och automation

    Author : Martin Andersson Ljus; [2013]
    Keywords : Technology and Engineering;

    Abstract : In times of increased environmental awareness, there exists a desire to not only build new environmentally friendly and renewable power generating units, but also to increase the efficiency of all existing technology. Wind power is such a renewable and environmentally friendly technology. READ MORE
