基于主干线/分支线模型的配网单线图自动生成方法

Automatic Generation Method of One-Line Diagram for Distribution Network Based on Trunk-Branch Line Model

配网单线图是一种电气接线图,其利用规定的图形符号和设备连线对配电网进行可视化,能显著提高配网管理的效率.针对配网单线图自动生成实际需要,本文提供了一种基于主干线/分支线模型的配网单线图自动生成方法.方法首先进行了主干线分支线的创建和分支布局方向的计算;然后进行了分支初始布局和局部拉伸;最后进行了分支局部收缩和自动布线.经过验证,基于主干线分支线模型的配网单线图自动生成方法,能自动生成满足准确性、美观性等要求的单线图.

The one-line diagram for a distribution network,as an electrical wiring diagram,uses the specified graphic symbols and equipment connections to visualize the distribution network,significantly improving the efficiency of distribution network management.Aiming at the actual needs for automatic generation of one-line diagrams for a distribution network,this paper provides an automatic generation method based on the trunk-branch line model.The method first creates the trunk line and branch lines and calculates the branch layout direction;then plans the initial branch layout and performs partial stretching;and finally enables branch partial contraction and automatic routing.It has been verified that this automatic generation method can automatically generate the one-line diagrams that meet the requirements of accuracy and aesthetics.
