摘　　要：针对传统特高压输电线选线设计模式优化方法存在优化时间较长,优化成本较高等问题,提出基于蚁群算法的特高压输电线选线设计模式优化方法。在特高压输电线选线设计模式中,利用成本型电线选线的定量指标特征值隶属度和效益型选线的定量指标特征值隶属度,建立特高压输电线选线模型,给出特高压输电线选线评价指标权重向量目标函数。将选线设计方案生成随机种群,通过遗传算法的交叉对特高压输电线目标函数进行优化,得到选线设计方案适应度函数;利用Max-Min蚁群算法对各选线设计方案进行信息素更新,并获取选线设计方案适应度函数与信息素浓度之间的关系,进一步选取选线设计方案,得到目标函数最优解,实现对特高压输电线选线设计模式的优化。实验结果证明,所提方法优化前时间相比优化后降低了0. 63min,且优化成本少于其他方法,说明所提方法优化结果较为理想。Aiming at the problems of traditional UHV transmission line selection design optimization method,such as long optimization time and high optimization cost, an optimization method based on ant colony algorithm for UHV transmission line selection design is proposed. In the line selection design mode of UHV transmission lines, the selection model of UHV transmission lines was established and the UHV transmission line selection model was established by using the quantitative index characteristic value of cost-type line selection and the membership index of quantitative index characteristics of benefit line selection. Power transmission line selection evaluation index weight vector target function Generate a random population for the line selection design program, optimize the objective function of the UHV transmission line through the intersection of genetic algorithms, and obtain the fitness function of the line selection design program;use the Max-Min ant colony algorithm to perform pheromone update for each line selection plan The relationship between the fitness function and the pheromone concentration of the line selection design program is obtained, and the line selection design scheme is further selected to obtain the optimal solution of the objective function, and the line selection design mode of the UHV transmission line is optimized. The experimental results show that the proposed method reduces the time before optimization by 0. 63 rain compared with that after optimization, and the optimization cost is less than other methods, indicating that the optimization results of the proposed method are relatively satisfactory.
