Research on location selection method of 5G base station in substation considering radiation disturbance and conduction disturbance

With the 5G communication network in the power grid construction and application of rapid development, especially the popularity of substation applications within 5G, a growing number of 5G base stations need to build within the substation, 5G Base Stations within the communication equipment within the substation under complicated environment by the electromagnetic disturbance intensity, the protection method and immunity limits has become an important problem need to cognitive and address. Substation electromagnetic protection areas for relay protection, stability control, electric power automation equipment to carry out a large amount of research, but 5G communications equipment as a new system, especially the base station in order to achieve better communication must possess two basic characteristics of the intensified the complexity of electromagnetic compatibility, first of all, the existence of antenna under complex electromagnetic environment, when receiving and receiving signals, it also becomes a sensitive port for induction of external electromagnetic interference. Second, for the omnidirectional communication capability expected by the 5G base station placed in the substation, it is necessary to find an appropriate installation position in the central area of the station, which is mostly an area with strong electromagnetic field. To cognitive substation in complex electromagnetic environment on the influence of 5G Base Stations, for selection of 5G Base Stations and electromagnetic disturbance protection for reference, this paper puts forward 5 g base stations within the substation siting electromagnetic disturbance factors to consider and analysis method, is an object with a 500 kV substation expounds the analysis process, and discusses the main influencing factors, the location of the suppression method and suggestion, it provides reference for improving electromagnetic compatibility of secondary equipment and 5G communication equipment in substation and deployment of 5G communication equipment in substation.
