Embodiment Construction
[0070] In the following description, specific details such as specific system structures and technologies are presented for the purpose of illustration rather than limitation, so as to thoroughly understand the embodiments of the present invention. It will be apparent, however, to one skilled in the art that the invention may be practiced in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.
[0071] In order to illustrate the technical solutions of the present invention, specific examples are used below to illustrate.
[0072] In order to reduce the impact of power failure as much as possible, two distribution lines can be connected through a switch to realize the transfer between loads. The switch used to connect the two distribution lines is called a "connection switch". In the proc...

The invention is suitable for the technical field of electric power systems, and provides a power distribution network fault recovery method and device and a terminal device. The power distribution network fault recovery method comprises the steps of under the condition that a fault occurrence position is not adjacent to an interconnection switch of a power distribution network, according to the historical electricity load capacity of a plurality of transformer areas needing to be transferred corresponding to the fault occurrence position, obtaining a first transfer load total amount of the plurality of transformer areas needing transfer at a transfer moment; when the redundant electric quantity corresponding to the interconnection switch is smaller than the first transfer load total quantity, determining a to-be-removed transformer area in the plurality of transformer areas needing transfer according to a pre-acquired power utilization difference dynamic evaluation score of the transformer areas needing transfer at the transfer moment; and cutting off the to-be-cut-off transformer area, and closing the interconnection switch, so that the transfer recovery is carried out on the transfer-required transformer areas except the to-be-cut-off transformer area in the plurality of transfer-required transformer areas. According to the invention, the transfer resource utilization rate can be improved.
Description
technical field [0001] The invention belongs to the technical field of power systems, and in particular relates to a distribution network fault recovery method, device and terminal equipment. Background technique [0002] When the distribution network fails, the rapid isolation and self-healing technology can be used to restore the distribution network fault, so as to reduce the fault outage time and improve the power supply reliability of the distribution network. Distribution network fault recovery means that after a distribution network fault occurs, by determining the optimal switch combination scheme, the goals of restoring the most out-of-power load, the least number of switching operations, the smallest network loss, and the fewest complaints are achieved, and at the same time satisfy the distribution network after restoration. Grid connectivity, radial, non-overloading of feeders, etc. [0003] However, in the process of formulating the existing fault transfer recov...
