2022 IEEE International Conference on High Voltage Engineering and Application (ICHVE 2022)

Carrying out power tower sharing cooperation with the power grid is an effective way to solve the problem of base station site resources. However, the current sharing pilot and technical demonstration do not involve the high-voltage dangerous impact and protection under the condition of short- circuit fault, which undoubtedly lays a great potential safety hazard for the subsequent large-scale promotion and Application. Aiming at the power frequency ground potential rise when the high-voltage line is short circuited to the ground, this paper establishes the corresponding simulation model of the shared tower, completes the simulation calculation of the ground potential rise distribution of the ground network under different short-circuit currents and different earth resistivity, obtains the impact of the power frequency ground potential rise on the 5g base station through analysis and summary, and puts forward the overall safety protection construction scheme of the high-voltage power tower shared by
