Embodiment 1
[0065] Example one, as Figure 4 Shown is a schematic diagram of a distribution area connection of part of the distribution network of the present invention, wherein Z1 to Z3 respectively represent three distribution areas, A1 to A3 respectively represent three distribution nodes, and B(i, j) represent A power terminal, E1 represents the energy storage station. The lines within the same distribution area are represented by solid lines, and the connecting lines across areas are represented by dashed lines.
[0066] when Figure 4 When the power consumption terminal B(1,1) in the power distribution system fails, the power distribution node A1 is disconnected, and the power distribution area Z1 is isolated. At this time, the fault point is located. Due to the failure of the power terminal B(1,1), the sub-intelligent device W(1,1) at the power-consuming terminal detects the fault information, and the fault current flows, and sends the fault to other sub-intelligent devices and t...
Embodiment 2
[0068] Example two, as Figure 5 Shown is another schematic diagram of the connection of distribution areas of part of the distribution network of the present invention, wherein Z1 to Z5 respectively represent five distribution areas, A1 to A5 respectively represent five distribution nodes, and B(i, j) represent one Power terminals, E1 and E2 represent energy storage stations. The lines within the same distribution area are represented by solid lines, and the connecting lines across areas are represented by dashed lines. The energy storage station is directly connected to the power consumption terminal through which three or more lines pass.
[0069] when Figure 5 When the power distribution node A1 in the system fails, the power distribution node A1 is disconnected, and the power distribution area Z1 is isolated. At this time, the fault point is located. Due to the failure of the power distribution node A1, the total intelligent device W1 will detect the fault information...
