摘　　要：提出了一种应用人工智能算法实现地区电网运行单线图自动布局的新方法。通过图模一体化技术生成标准变电站接线图,根据变电站个数和形状等因素确定布局区,在布局区依次进行变电站定位和线路走线形成一种布局方案,并建立了以线路总长度最短为优化目标的数学模型。提出了分类随机扰动失活粒子和相似粒子以保持粒子活性和搜索前期种群多样性的改进粒子群优化算法,应用该算法求解按固定布线顺序走线的最优布局,最后优化布线顺序以进一步减少线路交叉。应用实例表明智能自动布局的结果美观且能有效支持调度决策。A novel approach to intelligent automatic layout of single-line diagrams for the regional network is presented. The standard substation wiring diagrams are generated by the integration of graph and model technique. The layout area is defined according to the number and configuration of the substations. The layout scheme is formed after completing substation placement and line routing orderly in the layout area. A mathematical model with minimal total line length as the optimization objective is developed. A modified particle swarm optimization algorithm for disturbing inactivated particles and similar particles respectively and randomly is proposed to search for the best layout of single-line diagrams in the fixed routing sequence. Finally,the routing sequence is optimized to further reduce the crossing of lines. The application examples show that the result of intelligent automatic layout is aesthetic and effective for dispatching decision-making.
