  1. 16. Distribution Grid Fault Location : An Analysis of Methods for Fault Location in LV and MV Power Distribution Grids

    University essay from Uppsala universitet/Institutionen för teknikvetenskaper

    Author : Jonas von Euler-Chelpin; [2018]
    Keywords : Fault Location; Power Grid; Electricity; Cable fault; Power Distribution; Distribution Grid;

    Abstract : Outages and power interruptions are a common and unenviable part of power distribution system operations. Growing demands on reliability in distribution systems has opened up for new technological solutions for fault location at MV and LV level in distribution systems, previously reserved for transmission systems.

  3. 17. The impacts of series compensated EHV lines on distance protection, and a proposed new mitigation solution

    University essay from KTH/Elektroteknisk teori och konstruktion

    Author : Syed Arif Ullah Shah; [2017]
    Keywords : Series compensation; metal oxide varistor; voltage inversion; current inversion; sub-synchronous oscillation; quadrilateral characteristic distance relay; digital high-pass filter; Seriekompensation; metalloxidvaristor; spänningsinversion; ströminversion; subsynkron oscillation; fyrsidig karakteristiskt distansrelä; digitalt högpassfilter;

    Abstract : Series compensation is extensively applied to the transmission lines to increase the power transfer capability of transmission lines, reduce transmission losses, improve voltage profiles, and improve power oscillation damping and transient stability of power systems. But it modifies the apparent impedance of the transmission lines during fault conditions and might cause the distance protection of transmission lines to encounter directional discrimination issues and reach problems.

  4. 18. Implementation of a Distributed Fault-Tolerant NoC-based Architecture for the Single-Event Upset Detector

    University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Author : Eleftherios Kyriakakis; [2017]
    Keywords : ;

    Abstract : Today, with the rise of the private sector in space exploration, space missions are becoming more frequent than before. This in relation to the fact that modern electronics scale both faster and denser, the effects of radiation become a critical design requirement for fault-tolerance in on-board space computer systems.

  5. 19. The Impacts of UHV AC Transmission Lines on Traditional Line Differential Protection Functions

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

    Author : MD Zakaria Habib; [2016]
    Keywords : UHV lines phenomenon; Line differential protection; Capacitive charging current compensation;

    Abstract : UHV transmission lines have several advantages when it comes to transferring of bulk amount ofpower in long distances. Although the technology is available from 1980’s, the number of UHVtransmission lines around the world has been increased in the beginning of this century in orderto supply the high demand of electricity.

  6. 20. Fault Location and Classification for Transmission Line Based on Wavelet Transform

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

    Author : Qiuhong Wang; [2016]
    Keywords : Traveling wave; fault location; fault classification; wavelet transform; ATP EMTP.; Vågrörelse; fellokalisering; felklassificering; wavelet transformation; ATP EMTP;

    Abstract : With the rapid development of power systems, locating and classifying faults is critical to the continuity and reliability of the transmission system. In this thesis, a traveling-wave based technique for fault location and classification on high voltage and extremely high-voltage transmission lines is proposed. READ MORE
