基于物联网和边缘节点计算的配网分布式自愈技术研究

Distributed self-healing technology of distribution network based on Internet of Things and edge node computing

电力物联网飞速发展,使得大量物联终端接入配电网,增加了安装维护的工作量。另外,目前配电网系统单相接地故障自愈能力差,高阻接地故障和断线故障的自愈能力不足,缺乏分布式能源高渗透率系统接地故障研究。为此,本研究融合了物联网技术和边缘节点计算,在中压配网故障自愈支撑技术方面取得突破,并在此基础上,结合现场配网终端进行试运行。结果表明,现场运行效果良好,可快速实现中压配电网一体化故障处理。

With the rapid development of power Internet of Things,a large number of iot terminals are connected to the distribution network,which increases a lot of installation and maintenance work.In addition,the self-healing ability of single-phase grounding fault in distribution system is poor,the self-healing ability of high-resistance grounding fault and disconnection fault is lacking,and the research on grounding fault of distributed energy system with high permeability is lacking.Therefore,this study integrates the Internet of Things technology and edge node computing,and makes a breakthrough in the support technology of fault self-healing of medium voltage distribution network.On the basis of this research,the trial operation is carried out in combination with the on-site distribution network terminal,and the on-site operation effect is good,which can quickly realize the integrated fault handling of medium voltage distribution network.
