Abstract

The invention discloses a fault line patrol troubleshooting planning method and system in a single / double cooperative mode, and the method comprises the steps: firstly designing an optimal line patrolmodel for single-mode fault troubleshooting, and analyzing the calculation complexity of the optimal line patrol model; and secondly, in order to accord with field operation characteristics, derivingand constructing an efficient cooperative line patrol investigation model in a double-cooperative mode on the basis of the single-mode model, wherein the model can simultaneously consider the minimumtotal investigation task amount and the more balanced inter-queue allocation task amount; then, on the basis of discussing the difference between the two models, designing a solution scheme of the two models by combining Dijkstra and a depth-first search algorithm; finally, by taking an IEEE 33-Bus system as an example, verifying the accuracy and high efficiency of the provided line patrol investigation model.

Description

technical field [0001] The invention relates to the technical field of electric power fault maintenance, in particular to a method and system for fault inspection and planning in a single / double cooperative mode. Background technique [0002] For a long time, the planning and construction of electric power has the problem of emphasizing power generation and neglecting distribution, which makes the development of urban distribution network relatively lag behind. Problems related to the distribution network are manifested in: ① long power supply radius and high line loss; ② unreasonable network structure and inflexible operation mode; and ③ rapid load growth and tight land for power grid construction. In view of this, the possibility of distribution network failure is difficult to avoid. Although it is possible to locate faults in combination with power distribution terminals, due to reasons such as investment costs, most lines in the distribution network have not yet undergo...
