5G与WiFi6在水电站智慧运维中的应用研究

Research on application of 5G and WiFi6 in smart operation and maintenance of Hydropower Station

科技进步使智慧水电站的建设越来越成熟,除传统有线网络接入之外,稳定、高速、安全的全厂无线网络覆盖是水电站智慧运维工作中的重要基础设施之一。通过对5G与WiFi6在水电站无线组网方式中的对比研究,分析了5G,WiFi6及主要LPWAN技术的差异性与互补性,根据水电站智慧运维各主要业务的无线网络接入与网络安全需求,提出了现阶段以工作在非授权频段的WiFi6+LoRa技术作为水电站主要组网方式,并为长期演进至以工作在授权频段的5G+NB-IoT技术为主要组网方式预留条件。

With the gradual maturity of the objective conditions for scientific and technological progress,in addition to traditional wired network access,stable,high-speed,and safe plant-wide wireless network coverage is one of the important foundation facilities for smart operation and maintenance of hydropower stations.Through the comparative study of 5G and WiFi6 in the wireless networking of hydropower stations,the differences and complementarities of 5G and WiFi6 are analyzed.According to the wireless network access and network security requirements of the main businesses of smart operation and maintenance of hydropower stations,the solution is proposed:in the current stage,WiFi6+Lora technology working in an unlicensed frequency band is used as the main networking method for hydropower stations,and long-term evolution to using 5G+NB-IoT technology working in a licensed frequency band is reserved as the main networking method.
