摘　　要：调度大屏输电网潮流图的自动生成,可分解为单线图布局、单线图布线、实时数据接入3个步骤。文中研究布局问题,将其分解为供区布局求解和供区内变电站布局求解,以降低求解的维度,提高求解效率。提出了基于Java脚本控制的可缩放矢量图形(SVG)人工辅助布局工具以及自动求解算法。对供区内变电站布局求解,建立了考虑布线效果的目标函数,即线路交叉尽可能少,相连变电站之间距离尽可能短,避免布局—布线多次循环;并提出了一种基于模拟退火算法的自动布局算法,它在变电站地理坐标离散化或其他任意的初始解上进行计算,可获得全局优化解。布局后再进行优化走线,最后自动生成的电网调度单线图,布局清晰,效果良好。The automatic generation of the transmission network single-line power flow diagram for dispatching large screen display can be divided into three steps, namely, the single-line diagram layout, the single-line routing, and the real-time data access. The automatic layout of the single-line power flow diagram is studied, which can be decomposed into the supply area layout and substation layout within the supply area to reduce the dimensions of a problem and increase the efficiency for solution. A visual assistance layout tool based on scalable vector graphics （SVG） controlled by Java Script and an automatic layout algorithm are proposed. For the substation layout within the supply area, a compressive objective function is suggested, that is, the intersections should be as few as possible and the distance between substations as short as possible so as to avoid repeated cycles of layout-routing. An automatic layout algorithm based on simulated annealing is provided, by which global optimal solution can be obtained from an initial layout obtained by discretization of the substation geographical coordinates followed by optimization routing. The final dispatching single-line power flow diagram generated after the automatic layout is distinct and with very satisfied effect.
