Based on the ratio of the sum of the fault component voltage phasors across the two terminals in the transmission line to the sum of the current phasors through the same line, which is defined as fault component integrated impedance in this paper, a new transmission-line pilot protection principle is proposed. When an external fault occurs, the amplitude of the fault component integrated impedance...
Considering that the single-phase to earth fault is the main fault type on overhead transmission lines, the single-phase reclosure (SPR) scheme is applied widely to improve the stability of power system in China. Utilizing one-terminal post-fault measurements before the faulty phase is tripped and the measurements of the sound phases when the tripped faulty phase is waiting for SPR, the fault resistance...
