Embodiment 1
[0030] In the first embodiment, a centralized feeder automation fault handling method for a distribution network is provided, please refer to Figure 1-Figure 3 , the method includes:
[0031] Step 1: Carry out fault location, according to the fault information detected by each power distribution terminal or fault indicator, combined with the fault information of the substation, start the fault processing program, determine the fault type (short circuit fault / ground fault) and the location of occurrence; the fault type The identification is based on the different starting signals, the short-circuit fault is identified based on the substation switch tripping and protection action signals, and the ground fault is identified based on the voltage loss of the busbar. Fault location is based on the current flow direction, according to the principle that there is a fault signal upstream of the fault point, and there is no fault signal downstream of the fault point.
[0032] Step 2: ...
