摘要

为了解决变电构架设计中的优化问题，采用改进麻雀搜索算法对其进行优化设计。在基本麻雀搜索算法中引入Circle混沌映射，以提高种群的多样性和算法的全局搜索能力；引入萤火虫算法对麻雀搜索算法进行扰动更新，使其易于跳出局部最优。建立尺寸优化的数学模型，采用罚函数法处理约束条件。先将改进后的算法用于典型桁架算例分析，证明其稳定性与有效性，再将其用于变电构架的优化设计，结果表明，采用改进后的麻雀搜索算法能够有效提升变电构架的优化效果。

Abstract

In order to solve the optimization problem in the design of substation structures, the improved sparrow search algorithm was used for its optimization design. The Circle chaotic map was introduced into the basic sparrow search algorithm to improve the diversity of the population and the global search ability of the algorithm. The firefly algorithm was introduced to update the sparrow search algorithm to make it easy to jump out of the local optimum. A mathematical model of size optimization was established, and the penalty function method was utilized to deal with constraints. The improved algorithm was first used to analyze typical truss examples to prove its stability and effectiveness, and then applied to the optimization design of substation frames. The results show that the improved sparrow search algorithm can effectively improve the optimization effect of substation structures.
