摘　　要：电网图自动布局对改进电力系统分析方法和提高工作效率具有重要意义。文中提出了以5种作用力为基础的拓扑图动力学模型,构建了运动方程与稳态方程;并提出一种拓扑图进化策略,能够克服单纯动力学模型局部寻优的缺陷,增强了拓扑图自动布局和优化的能力。所提模型及优化策略不仅考虑到不依赖于任何位置信息进行电网图自动全新布局,还支持对已有的电网图进行自动适应并补充布局,因此能够适应各种规模和电压等级的电网,自动布局效果良好且速度快。将该模型应用于PSD-Clique软件,取得了理想效果。An efficient automatic layout method for power grid diagram will significantly contribute to improvementof power system analysismethod and increasing the working efficiency.Based on five kinds of force,a dynamics model of topological graph is presented,andthe motion equation and steady state equation are established.An evolutionary strategy of topological graph,which can overcome the local optimization defect of simple dynamics model as well as improve the automatic layoutand optimization ability of topological graph,is proposed.The dynamics model and evolutionary strategy can not only achieve the fully automatic layout of a new diagram without depending on any position information,but also automatically adapt and add the existing layout,thereforecan be applied to power grid of any scale,any voltage class,with high-quality result and less time-consuming.The model proposed in this paper has been embedded in PSD-Clique,and obtains idealeffect.
