摘　　要：当前,电力物联网作为电力行业向能源互联网发展革新的过渡形态,在监控、管理等方向面临着新时代数字化变革。现有数据传输方案应对变革乏力,急需引入先进的数据传输方案作为数字化先导,引领并完善电力物联网的建设。第五代移动通信技术(5G)因具有带宽、时延、传输速率等性能指标上的优势,受到了各行各业青睐,在未来也被期望能够与电力物联网深度融合,应对发展挑战。为此,该文以电力物联网数据传输方案为研究对象,首先阐述了电力物联网建设完善过程中数据传输的重要性,通过梳理电力物联网构架,分析了其中的数据传输网络,将数据传输方案应用场景划分为采集、控制和电力业务信息传递三大类;然后,以此为据,梳理、讨论了现有数据传输方案在电网中的应用现状,并结合当下数字化变革分析了电力物联网对数据传输方案的新需求;随后,从5G技术特征出发,分析了5G技术在电力物联网中的适用性,并对其在电力物联网中的研究现状进行了概述;最后,指出5G技术在电力物联网中应用将会面临的挑战,并展望了电力物联网数据传输方案将承载多元化的海量信息和以一体化通信架构发展的趋势,以期为电力物联网的深入研究和实践提供参考。At present,power internet of things(PIoT)is a transitional form which represents development and innovation of the power industry towards the Energy Internet.It is facing a new era of digital transformation in the directions such as monitoring and management.Existing data transmission schemes are too weak to cope with the change.It is urgent to introduce advanced data transmission schemes as a digital forerunner to lead and improve the construction of PIoT.The 5th generation mobile networks(5G)is favored by all walks of life due to its advantages in performance indicators such as bandwidth,time delay,and transmission.In the future,5G is also expected to be deeply integrated with the PIoT,in order to meet development challenges.Therefore,the article focused on the data transmission technologies in PIoT,firstly expounded the importance of data transmission in the process of building PIoT,analyzed the data transmission network among PIoT through combing the PIoT architecture,and divided the data transmission schemes’application scenarios into three categories:collection,control,and power business information transmission.Then used the three categories as a basis to sort out and discuss the application status of the existing data transmission schemes in PIoT,and combining with the current digital transformation,analyzed the new demands of PIoT for data transmission schemes.Next,starting from the technical features of 5G technology itself,the authors analyzed its applicability in PIoT,and summarized 5G’s research status in PIoT.Finally,the authors pointed out challenges that 5G technology may meet when is applied into PIoT at future.What’s more,the trend that data transmission schemes will carry in PIoT was pointed out,which not only will carry extremely large amounts of diversified data information,but also will develop with an integrated communication architecture.The authors hope provide reference for the research and practice of PIoT.
