摘要
配电网中过电压类故障因其对电力设备具有破坏性且需要快速响应和处理,不必进入泛在电力物联网云平台进行数据采集和集成,而是采用本地化控制、分布式处理的方式进行边缘计算。面向泛在电力物联网,将边缘计算技术应用于单相接地故障响应边缘信息处理。依据IEC 62939智能电网用户接口标准,设计了配电网故障边缘计算节点(Distribution Power Network Fault Edge Computing Node,DPNF-ECN)架构,提出关键技术的实现方法,构建了基于边缘计算分层协治的配电网故障识别与响应模型。最后以某石化企业电网为例,构建了配电网故障识别边缘节点构架。
Single-phase grounding fault in distribution network needs fast response and processing because of its destructive overvoltage.Instead of entering the ubiquitous cloud platform for data acquisition and integration,it uses localized control and distributed processing for edge calculation.Faced with the ubiquitous power internet of things,edge computing technology is applied to edge information processing of single-phase grounding fault response.According to IEC 62939 smart grid user interface standards,the architecture of Distribution Power Network Fault Edge Computing Node(DPNF-ECN)is designed,the implementation method of key technologies is proposed,and the distribution network fault identification and response model based on edge computing hierarchical co-treatment is constructed.Finally,taking a petrochemical enterprise power grid as an example,the structure of the distribution network fault identification edge node is constructed.
