Analysis of the influence of power frequency electromagnetic field in substation on 5G base station deployment

China's power grid is progressively advancing towards smart technology. With increasing substation voltage levels, more 5G base stations are being integrated into substations. The presence of external antennas poses challenges for electromagnetic protection in these 5G base stations. This study focuses on deploying 5G base stations within substations, selecting a specific substation for physical modeling. It simulates the complex power-frequency electromagnetic field environment within the station and compares these simulations with actual measurements to validate their accuracy. Ultimately, by comparing and analyzing the simulation results with relevant standards for substation electromagnetic environments, the study determines the optimal deployment scope for 5G communication equipment in substations. This research provides theoretical insights for designing effective 5G deployment strategies in substations.
