Research on Check Method of Feeder Topology Model for Distribution Main Station

摘要

Cooperative control between intelligent distributed Feeder Automation and main station centralized Feeder Automation can improve the performance of fault handling. At present, feeder side topology is derived from the automatic identification of distribution terminals. The main station side topology is imported by the incremental import of geographic information system or production management system, but there are some problems, such as the topology confusion. In order to realize the power supply technology of fault isolation and non-fault area restoration based on intelligent distributed Feeder Automation and main station reserve, unify topology model, this paper present a method that once the static topology or topology operation mode is changed, the agent terminal initiates the function of topology query and generates the feeder topology file which will be uploaded to the main station for checking. Finally, the main station side topology can be corrected. The feasibility of the check scheme is verified by experiments, which meets the requirements of the distribution network.
