摘要：As the increasing requirement of power supply reliability, multi-contact distribution network is more and more widely used. However, the application of distributed intelligent feeder automation (DIFA) in multi-contact distribution network will face the problem of topology identification. To solve the problem, this paper proposes a topology distributed configuration method based on topology unit. In the method, we take each smart terminal unit (STU) as the basic unit to store topology information, which is represented by the adjacency of switches. And the nodes information in topology structure is generated by the configuration information automatically. Each STU only stores the topology information of its managing area, called topology unit information, and obtains the topology unit information in other STU by peer-to-peer network. Finally, we can get the topology structure of desired region by the connection of topology units. The method has the advantages of high maintenance efficiency and fast generation speed, which can lay the foundation for the application of DIFA in multi-contact distribution network.
