| 摘要: |
| 馈线拓扑分析是实现馈线自动化的基础，智能分布式馈线自动化(Distributed Intelligent Feeder Automation, DIFA)的馈线拓扑分析由配电终端自主实现面临着巨大的挑战。首先研究了FA应用的馈线拓扑模型，把电源、线路、母线和负荷等电气元件抽象为节点，以开关为边-电气元件为节点的多叉树表示的馈线拓扑作为DIFA馈线拓扑模型。提出了基于拓扑片的馈线拓扑分散配置方法，把每个配电终端覆盖的区域定义为拓扑片，每个配电终端配置存储拓扑片信息。把拓扑片的邻接关系用配电终端的邻接关系来定义，并映射成开关邻接关系。在拓扑片的配置中显性配置开关邻接关系，隐性包含线路节点、母线节点和负荷节点。最后提出了拓扑片拼接的馈线拓扑静态分析方法。所提出的基于拓扑片的馈线拓扑分析方法适用于DIFA，由配电终端自主实现，具有分析速度快和配置简单的优势。 |

| Abstract: |
| Feeder topology analysis is the basis of feeder automation. The feeder topology identification of Intelligent Distributed Feeder Automation (DIFA) is faced with great challenges by the distribution terminal. This paper firstly studies the feeder topology model of FA application, abstracts the electrical components such as power supply, line, bus and load into nodes, and takes feeder topology represented by multi-way tree whose edge is switch and node is electrical element as DIFA feeder topology model. A topology decentralized configuration method based on topological slices is proposed. The area covered by each distribution terminal is defined as a topology slice, and each distribution terminal is configured to store topology information. The adjacency of the topological slices is defined by the adjacency of the distribution terminal and mapped into the switch adjacency. In the configuration of the topology, it dominantly configures the switch adjacency and invisibly contains line nodes, bus nodes and load nodes. Finally, a topology analysis method of feeder topology is proposed. The feeder topology analysis method based on topological slices stitching is applied to DIFA, which is realized by the distribution terminal. It has the advantages of fast analysis and simple configuration. This work is supported by Science and Technology of State Grid Jiangsu Electric Power Company (No. J2016041). |
