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。Here,to solve the optimization problem in design of substation structure,an improved sparrow search algorithm(ISSA)was adopted for its optimization design.Introducing Circle chaotic mapping into the basic sparrow search algorithm to improve population diversity and the algorithm’s global search ability.Firefly algorithm was introduced to perturb and update the sparrow search algorithm,and make it easy to jump out of local optimum.A mathematical model was established for size optimization and the penalty function method was used to handle constraint conditions.Firstly,the improved sparrow search algorithm was applied in analysis of typical truss examples to demonstrate its stability and effectiveness.Then,it was applied in optimization design of substation structure.The results showed that the improved sparrow search algorithm can effectively improve the optimization effect of substation structure.
