电力CPS环境下电力4G无线专网向5G演进策略

构建高效连接、大容量带宽、低通信时延的电力无线专网，是电力信息物理系统（cyber physical system, CPS）业务可靠运行的重要保障，有必要对电力CPS环境下电力无线专网进行研究。首先分析了电力CPS环境下电力业务对通信网络的需求，结合电力业务特征研究了5G通信技术的通信组网架构。然后结合电力业务需求和5G通技术特点，提出了电力4G无线专网向5G演进目标，并构建了循序渐进的演进思路。分别提出电力4G无线专网终端、基站、回传网、核心网的演进策略。最后，对电力无线专网的演进策略进行了展望。

Evolution Strategy of 4G Wireless Private Network to 5G in Power CPS Environment

To build an electric power wireless private network with high-efficiency connection,large-capacity bandwidth and lowlatency communication is an important guarantee for the reliable operation of power cyber physical system(CPS).It is therefore necessary to study the electric power wireless private network in the environment of electric power CPS.Firstly,we analyze the demands of power business for communication network under the power CPS environment,and studies the communication network architecture of 5G communication technology combined with the characteristics of power business.Secondly,based on the demand of electric power business and the characteristics of 5G communication technology,the evolution goal of 4G wireless private network to 5G is proposed,and a step-by-step evolution path is constructed.Thirdly,the evolution strategy for 4G wireless private network terminal,base station,backhaul network and core network is proposed respectively.Finally,the evolution strategy of power wireless private network is forecasted.
