  3. 3. 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.
