5G电力专网架构及关键技术

Architecture and Key Technologies of 5G Power Private Network

随着5G网络的建设和关键技术的发展,5G专网和电力应用开始大规模融合,催生出能适应电力需求的5G电力专网。首先,梳理电力“发”、“输”、“变”、“配”、“用”多个环节各类业务对通信网络时延、带宽、覆盖范围等指标的初步要求,并通过变电站智能巡检、配网差动保护、计量自动化三大典型电力业务场景分析电力业务对通信网络时延、带宽、可靠性、连接数等性能的详细需求;其次,重点阐述适合电力业务场景需求的5G软、硬切片专网方案和公网专用、专网专用的5G核心网组网架构,同时分析5G核心网5G LAN、端边协同等关键技术;最后,通过实际落地的5G电力专网案例和成果验证说明5G电力专网已基本能满足电力业务对带宽、时延、安全等需求,同时提出5G电力专网规模化商业应用还需解决5G切片颗粒度偏大、业务开通不够智能化、产业链升级缓慢、关键技术还需迭代等问题。

With the construction of 5G networks and the development of its key technologies,5G private networks and power applications have been widely integrated,thus giving birth to the 5G power private network that can meet the electricity demand.First of all,the preliminary requirements of power“generation”,“transmission”,“transformation”,“distribution”and“utilization”on communication network delay,bandwidth,and coverage are sorted out.Then,through the three typical power business scenarios of substation intelligent patrol inspection,distribution network differential protection,and measurement automation,the detailed requirements of power business on communication network delay,bandwidth,reliability,and the number of connections are analyzed.Secondly,this paper focuses on the 5G soft and hard slice private network schemes that meet the requirements of power business scenarios,as well as the 5G core networking architecture dedicated to public and private networks.In addition,key technologies such as 5G core network,5G LAN,and end-to-end collaboration are analyzed.Finally,the actual cases and results demonstrate that the 5G power private network can basically meet the requirements of power business for bandwidth,delay,and security.Moreover,we pointed out some issues that still need to be addressed in the commercial application of 5G power private networks,such as large 5G slice granularity,unintelligent business opening,slow industrial chain upgrading,and iteration of key technologies.
