面向配电物联网的中低压配电网拓扑建模

Topology Modeling of Medium-and Low-voltage Distribution Network for D-IoT

物联网技术与配电网深度融合形成的配电物联网提供了解决中低压配电网长期盲调盲控问题的新思路。针对目前现有的公共信息模型对配电物联网的描述和覆盖能力欠缺,本文首先扩展了公共信息模型中的低压设备模型和拓扑模型;然后分别在配电物联网云侧、边侧建立了考虑扩展分相的云侧低压配电网拓扑连接模型,以及边侧局部拓扑分析模型;最后给出了配电物联网云边协同的拓扑交互方法及采用的通信协议。本文提出的面向配电物联网中低压配电网拓扑模型与交互方法可以实现中低压配电网拓扑建模与交互。

The distribution internet of things(D-IoT)formed by the integration of internet of things(IoT)technology and distribution network provides a new idea to solve the problem of long-term blind operation and control of medium-and low-voltage distribution network.Considering that the existing common information model(CIM)lacks the capability to describe and cover D-IoT,the low-voltage equipment model and topology model in CIM are extended at first.Then,the cloud-side topology connection model of low-voltage distribution network that takes three-phase extension into consideration and the edge-side local topology analysis model for D-IoT are established,respectively.Finally,the topology interaction method and communication protocol for the cloud-edge collaboration in D-IoT are given.The topology model of medium-and low-voltage distribution network for D-IoT and the interaction method proposed in this paper can realize the topology modeling and interaction of medium-and low-voltage distribution network.
