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).
