摘　　要：由于电网结构的不断复杂化,传统由发至用的结构已经发生了根本性的改变,各种信息流和能量流的交互使得配网GIS单线图的自动生成变得日益困难。针对传统人工绘图方式存在的工作量大、效率低以及准确度不受控等弊端,同时由于人为绘图习惯的影响,绘制成品的可读性较低,无法满足日益更新的电网对自身维护和管理的要求。文中结合ST-number算法,进行原图的平面性判定,实现正交成图,将复杂的电气接线信息扁平化处理。基于IEEE118节点作为算例进行实验验证,结果显示该算法可实现复杂接线图的解耦,显著提升了成图效率和绘图的准确性。Due to the increasing complexity of power grid structure,the traditional structure from generation to use has undergone fundamental changes.The interaction of various information flows and energy flows makes the automatic generation of GIS single line diagram of distribution network increasingly difficult.The traditional manual drawing method has the disadvantages of heavy workload,low efficiency and uncontrolled accuracy.At the same time,due to the influence of human drawing habits,the readability of the finished drawing product is low,which can not meet the requirements of self maintenance and management of the increasingly updated power grid.In this paper,ST-number algorithm is used to determine the planarity of the original graph,realize the orthogonal mapping,and flatten the complex electrical wiring information.The experimental results based on IEEE118 bus show that the algorithm can decouple the complex wiring diagram and significantly improve the efficiency and accuracy of drawing.
