【摘要】 基于FIU馈线自动化方式,提出了适合不同网络结构、不同分段开关类型的可靠性费用计算模型。针对分段开关优化配置是一种以可靠性费用最小为目标函数的组合优化问题,提出用禁忌搜索(TS)法优化开关位置和数量,TS法采取对搜索历史的灵活记忆方法,指导搜索过程避开局部最优解,并通过优选初始解使其有较快的收敛速度。实例证明该算法全局搜索能力强、收敛快。更多还原

【Abstract】 Distribution automation systems must be decided upon d isconnection switch. The reliability is improved and custom interrupt loss is re duced by disconnect switch properly positioned in distribution networks. Reliabi lity cost consists of switch cost and custom interrupt loss. The custom interrup t loss is calculation by analyzing power supply reliability in relation to the t ype of switches and the construction of distribution networks on the basis of FT U feeder automation. Optimal switch device placement is a combinatorial optimiza tion problem with nonlinear and non-differentiable reliability cost objective f unction. Disconnect switch optimal is implemented by Tabu Search(TS) algorithm, which avoids the local optimal solution by remembering the history of search and has a rapid search speed by adaptive initial solution. Test results show that t he proposed method is suitable for switch placement optimization. The numerical results prove that the algorithm has the advantages of rapid search and good con vergent.更多还原
