    Author : Mattias Harrysson; [2014]
    Keywords : electric power system; transmission lines; Smart Grid; fault detection; fault location techniques; disruptions caused by storms; transmission fault; calculation of distance to fault; Statnett; one-side algorithms; two-side algorithms; fault types; fault location methods; one-ended fault location algorithm; reactance based algorithm; takagi method; fault location algorithms by saha; Harrysson; two-ended fault location estimation; fault resistance; Avstånd till fel; ABB; Statnett; Matlab; Simulink; Transmissions nätet; Avstånds till fel algorithmer; Fel lokalisering;

    Abstract : The rapid growth of the electric power system has in recent decades resulted in an increase of the number of transmission lines and total power outage in Norway. The challenge of a fast growing electrical grid has also resulted in huge increases of overhead lines and their total length. READ MORE

  3. 23. Adaptation of Legacy Codes to Context-Aware Composition using Aspect-Oriented Programming for Data Representation Conversion

    University essay from Institutionen för datavetenskap (DV)

    Author : Alisa Sotsenko; [2013]
    Keywords : aspect-oriented programing; context-aware composition; matrix multiplication; graph algorithm; data representation;

    Abstract :     Different computation problem domains such as sorting, matrix multiplication, etc. usually require different data representations and algorithms variants implementations in order to be adapted and re-designed to context-aware composition (CAC). READ MORE

  4. 24. 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

  5. 25. 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.
