摘要：Feeder topology representation method has an important impact on the research of distribution network. According to the structure of the feeder, this paper proposes a new representation method for feeder topology based on multiway tree. In the method, we take power, load, bus, and line in the feeder as nodes and take the switches as lines to connect the nodes to compose a multiway tree, which can represent feeder topology information. Switch state is important auxiliary information for multiway tree structure, and we use the two-dimensional array whose row number and column number both match the nodes number to store switches information between the nodes. The two-dimensional array establishes the one-to-one relationship between the line in the multiway tree and the actual switch. By the topology information and the control information, which is independent of each other, the method can not only describe the feeder structure completely, but also has the advantages of clear physical meaning, independent control elements and high access efficiency. It provides a new idea for the research on distribution network.
