云雾协同的泛在电力物联网构架在变电站工程中的应用

Application of Cloud-Fog Coordinated Ubiquitous Power Internet of Things Design in Substation Engineering

目前的电网设计处于信息互动的高级阶段,感知水平较高,正走向网络智能阶段,梳理当下的变电站系统设计体系可以发现,以往的场站端系统设计已经渗透着边缘下沉的理念。根据雾计算更靠近终端的思路,提出在变电站端接入点配备边缘雾计算设备,把大量就地采集的信息直接在本地接入点进行存储和处理,成为雾层。雾层服务器作为核心云平台的边缘下沉,协同计算,大幅提高实时分析与优化能力。结合目前泛在电力物联网建设和变电站控制系统特点,提出云雾协同的泛在电力物联网系统构架,系统分为“智、云、网、雾、端”五个层级,分析各层级的现状及问题,提出变电站端的建设方案。

The current grid design is in the advanced stage of information interaction,which is of a high level of perception and gradually moves toward the network intelligence stage.It can be found that the previous substation design has displayed the concept of edge calculation.According to the idea that the edge calculation is closer to the terminal,this paper proposes that the substation be equipped with edge computing device,which stores and processes a large amount of locally collected information directly in the substation and serves as fog calculation.As the edge of cloud platform,fog server collaborative computing greatly improves real-time analysis and optimization capabilities.Combined with the current construction goals of ubiquitous power internet of things and characteristics of substation control system,this paper proposes a five-level(intelligence,cloud,network,fog and terminal)cloud-fog coordinated ubiquitous power internet of things to analyze the status quo and problems of each level and propose the construction plan of the substation.
