Problems solved by technology

[0003] Although various swarm intelligent optimization algorithms have made some progress in solving the problem of transmission line inspection route optimization, there are still many deficiencies: for example, although PSO has a fast convergence speed, when the scale of power system inspections increases Premature problems are prone to occur, and the optimization process of GA takes a long time, while ACO needs to adjust multiple control parameters, which shows that the problem is sensitive to parameters

Abstract

The invention discloses a transmission line inspection path optimization method based on a differential crisscross optimization algorithm. The algorithm is a hybrid optimization algorithm composed of a differential evolution algorithm and a crisscross optimization algorithm. The crisscross optimization algorithm (DE-CSO) fuses the strong global search ability of the crisscross optimization algorithm and the local search ability of the differential evolution algorithm. The transmission line inspection path optimization method disclosed by the invention has the beneficial effects that the DE-CSO method disclosed by the invention is used for solving the multi-target transmission line inspection path problem in which a tower risk probability and the shortest path are considered at the same time, meanwhile the DE-CSO method has good global approximation ability and fast convergence performance, and thus having important practical significance of improving the line inspection planning level and improving the inspection efficiency.

Description

technical field [0001] The invention relates to an optimization method for a power transmission line inspection path, in particular to a transmission line inspection path optimization method based on a differential crossover algorithm (DE-CSO). Background technique [0002] The transmission line inspection is of great significance to the safe and stable operation of the transmission line. The optimization of the inspection path of the transmission line refers to the shortest inspection path distance through the optimization of the path under the premise of meeting the inspection tasks of the power department. At the same time, take into account the risk level of the tower. In recent years, there have been related studies using swarm intelligence optimization algorithms to solve such problems, such as particle swarm optimization algorithm (PSO), genetic algorithm (GA), ant colony algorithm (ACO) and so on. [0003] Although various swarm intelligent optimization algorithms h...
