Abstract

There are many hybrid transmission lines consisting of power cables and overhead lines. When a fault occurs, it is difficult to determine the exact location of the fault. In order to prevent further damage caused by reclosing when the cable faults, this paper proposes to build a differential protection for the cable line to realize the judgment of the internal fault of the cable line based on 5G communication technology. If it is judged that the fault is inside the cable line, then send the blocking signal to the relevant protection devices in the substations on both sides to block the function of reclosing, thereby preventing reclosing from cable faults. The fault discrimination algorithm of the system in different types of hybrid transmission lines and the key technology of the system are introduced.
