Cooperative control between intelligent distributed FA and main station centralized FA can achieve the optimal fault handling. In the case of cooperative control, the feeder topology is derived from the automatic identification of distribution terminals. The main station topology is derived from the incremental import of geographic information system or production management system, which is chaotic and inconsistent with the actual topology operation mode. In order to realize the power supply technology of fault isolation and non fault area restoration based on intelligent distributed FA and main station reserve, and unify the feeder topology model, this paper presents a method that once the static topology or topology operation mode is changed, the main smart terminal unit initiates the function of topology query and generates the feeder topology file, the model file is uploaded to the distribution main station, the static topology model and dynamic topology model of the main station are checked, which can achieve the correction of main station topology. The feasibility of the verification scheme is verified by experiments, which fully meets the requirements of the distribution network.
