  1. 6. 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

  3. 7. Dynamic Line Rating - Thermal Line Model and Control

    University essay from Lunds universitet/Industriell elektroteknik och automation

    Author : Martin Andersson Ljus; [2013]
    Keywords : Dynamic Line Rating; Overhead Line; Offshore Wind Farm; Thermal Line Model; PID regulator; Temperature Control; Heat Balance in an Overhead Line; Öland; Kårehamn; Conductor Surface Temperature; Wind Farm Output Reference Value; 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

  4. 8. Dynamic line rating implementation as an approach to handle wind power integration : A feasibility analysis in a sub-transmission system owned by Fortum Distribution AB

    University essay from KTH/Elektroteknisk teori och konstruktion

    Author : Saifal Talpur; [2013]
    Keywords : Regional grid; overhead conductor; wind power; real-time weather; dynamic line rating; static line rating; line current; conductor temperature; ampacity upgrading; economics;

    Abstract : Based on conventional static line rating method, the actual current carrying capability of overheadconductors cannot be judged. Due to continuous increment in electricity demand and the difficultiesassociated with new line constructions, the overhead lines are therefore required to be rated based on amethod that should establish their real-time capability in terms of electricity transmission.

  5. 9. The overhead line sag dependence on weather parameters and line current

    University essay from Institutionen för geovetenskaper

    Author : Elisabeth Lindberg; [2011]
    Keywords : Overhead lines; dynamic rating; real-time monitoring; conductor;

    Abstract : As the demand for energy increases, as well as the demand for renewable energy, Vattenfall, as network owner, receives many requests to connect new wind power to the grid. The limiting factor for how much wind power that can be connected to the grid is in this case the maximum current capacity of the overhead lines that is based on a line temperature limit. READ MORE

  6. 10. Simulation of line fault locator on HVDC Light electrode line

    University essay from Högskolan Väst/Avdelningen för data-, elektro- och lantmäteriteknik

    Author : Andreas Hermansson; [2010]
    Keywords : Line fault locator; TDR; Arc reflection; simulation; electrode line; HVDC;

    Abstract : In this bachelor thesis, cable fault locators are studied for use on the overhead electrode lines in the HVDC (High Voltage Direct Current) Light project Caprivi Link. The cable fault locators studied operates with the principle of travelling waves, where a pulse is sent in the tested conductor. READ MORE
