摘　　要：该文提出了一种自适应蚁群算法,对蚂蚁的状态转移策略进行改进,采用新的信息素更新规则并将路径上的信息素浓度限制在一个动态区间内,自适应地调整信息素强度Q和挥发因子ρ,有效地提高了蚁群算法全局寻优能力和收敛到最优解的速度。通过对Garver-6节点和IEEE-18节点系统的测试,结果表明了该方法的有效性。另外,为解决电网建设问题中高压输电铁塔塔上作业困难的问题,在深入调研了±800 k V特高压云广直流线路输电铁塔相关带电作业现状的基础上,设计了耐张塔专用多功能伸缩硬梯结构并进行了伸缩硬梯样品试制、实验测试以及现场试用。A self-adaption ant colony algorithm is proposed to solve the problems. In the self- adaption algorithm,state transition strategy combining deterministic selection with random selection is put forward,and a new rule is raised to update pheromone,the intensity of pheromone Q and volatile factor ρare adjusted adaptively which can improve the global searching ability and convergence of the ant colony algorithm effectively. The result of testing on Garver 6-bus and IEEE 18-bus system proved the feasibility and validity of the method. Moreover,in order to solve the problem of the operation difficulty on high voltage transmission tower,on the basic of present situation of related on-line operation of ± 800 k V HVDC transmission line,this paper designed a structure of special multi-function flexible ladder,and the related pilot test,experiment and the field trial had been carried out.
