Abstract

The limited space of the substation contains a lot of electrical equipment and voltages ranging from hundreds to several thousand volts, resulting in a complex electromagnetic environment in the substation. As the deployment of 5G base stations increases in substations in China, the power-frequency magnetic field in substations will cause problems, resulting in a location problem. This paper develops a circuit model for converter stations, and presents a calculation method that considers the geomagnetic permeability, 3-phase transmission mode, and erection direction influences. The correctness of the calculation method in this paper is verified by comparing the simulation results and calculation results of the substation model. The deployment conditions of 5G base stations in the substation are analyzed according to the national standard of the requirement and measurement methods of electromagnetic compatibility for mobile telecommunications equipment Part 17: 5G base station and ancillary equipment.
