摘要
低压配电网是电力物联网(EPIoT)最核心应用场合,智能低压配电网应实现向电力物联网的自然延伸。为此,现有低压配电网数据采集与自动化系统要发展成云-边缘节点-边缘设备的体系架构,而作为核心边缘节点的配变终端(TTU)必须具备快速迭代能力,以实现新旧多种业务的边缘融合和云边协同。为此,首先对支撑边缘节点的容器技术等关键技术进行了分析;然后提出配变终端边缘节点化和容器化的关键实现技术,包括硬件平台、软件架构、容器部署及交互、容器管理和云边协同等。最后,新增一种提出的低压回路监测终端(CTU),对配变终端新型应用场景进行了设计,从而论证了配变终端边缘节点化和容器化的必要性。
The low-voltage distribution network is the most core area of the application of electric power Internet of Things(EPIoT).It is necessary to extend the smart low-voltage distribution network to EPIoT in nature.Present data acquisition and automation system for low-voltage distribution network needs to be developed into the cloud-edge node-edge device system architecture.As a core edge node,distribution transformer terminal unit(TTU)should have a quick iteration capability to realize the edged fusion and cloud-edge coordination of various old/new businesses.To meet such technique requirements,the key technologies such as container technology to support edge node are analyzed firstly.Secondly,the key implementation technologies to make TTU becoming a containerized edge node are proposed including hardware platform,software architecture,container deployment and interaction,container management,coordination between cloud and edge.Finally,by adding a new low-voltage circuit terminal unit(CTU),the application scenario for TTU is designed and its necessity to become a containerized edge node is demonstrated.
