  • Method and system for traveling wave-based fault location of AC and DC transmission lines based on 5G communication
    Patent number: 12061223
    Abstract: A method and system for traveling wave-based fault location of AC and DC transmission lines based on 5G communication. The method includes: calibrating time based on time information sent by a 5G base station; generating synchronous sampling pulses by using the calibrated time and a crystal oscillator, collecting a current signal, and on this basis, detecting a fault instant and an arrival instant of traveling wave head of a local end; sending the arrival instant of traveling wave head of the local end to an opposite end through a 5G network; and calculating a distance from a fault to either end according to the arrival instant of traveling wave head of the local end, an arrival instant of traveling wave head of the opposite end, and a full length of a line.
