Problems solved by technology

[0004] Since maintenance plan optimization is a multi-objective, multi-constraint nonlinear combinatorial optimization problem, existing related algorithm research mainly focuses on Benders decomposition method and intelligent optimization algorithm. In recent years, intelligent optimization algorithm has been more and more widely applied to maintenance In the plan, typical heuristic search algorithms include genetic algorithm, particle swarm optimization algorithm, etc., but in the application scenarios with discrete variables, the results of calculation and maintenance plan obtained by genetic algorithm and particle swarm optimization algorithm are inaccurate

Abstract

The invention discloses an overhaul plan making method and system for power transmission equipment. The method comprises the following steps: obtaining the construction period of each power transmission equipment and a power failure window period capable of arranging overhaul; substituting the construction period of each power transmission device and the power failure window period capable of arranging overhaul into a pre-constructed overhaul plan optimization model, and performing calculation by utilizing an improved universal gravitation search algorithm to obtain overhaul time of each device; making an overhaul plan based on the overhaul time of each device, wherein the overhaul plan optimization model is constructed by taking minimum renewable energy power generation and minimum overhaul quantity distribution variance as targets and taking overhaul time requirements, power grid safety operation requirements and daily overhaul quantity requirements of the power grid for each deviceas constraints. The improved universal gravitation search algorithm based on the simulated annealing thought provided by the invention is suitable for solving the overhaul plan problem containing discrete variables, and the equipment overhaul time can be reasonably arranged.

Description

technical field [0001] The invention relates to automation technology, in particular to a method and system for formulating maintenance plans for power transmission equipment. Background technique [0002] According to the characteristics of the energy structure of each country, the distribution of energy supply and energy demand is reversed. The abundant clean energy such as wind power, photovoltaic and hydropower is mainly concentrated in areas far away from the load center. In order to achieve its effective consumption. For the preparation of power outage maintenance plans for high-voltage power transmission and transformation equipment (including 500kV and above voltage levels and some 220 / 330kV voltage levels of AC and DC lines and related busbars, main transformers and converters, etc.), guarantee The transmission and full consumption of renewable energy are the main factors that must be considered. [0003] Therefore, the main goal of transmission line maintenance p...
