    摘要:

    基于前文提出的支撑变电站为中心配电网(SCDN)单线图自动生成的数据—图形模型,阐述了第一阶段的接线图初始布局策略,重点解决SCDN馈线群以本变电站10 kV母线为中心的辐射布局问题。首先提出包含模块设计的整体流程,以及成图数据预处理;根据馈线拓扑分析,获取馈线群布局规划,并提出基于干线—支线拓扑模型的支线—干线布局模型。在对环路特性研究基础上,提出了环路和非环路的支线—干线布局模型及计算策略。继而提出了SCDN单馈线分裂图形的水平初始布局计算方法、SCDN单馈线分裂图形目标扇面角和旋转角计算方法、SCDN扇面拼接计算方法及广义开闭所虚拟联络开关节点简易聚合方法,从而形成SCDN初始图形。以5个实际110 kV变电站对提出的模型及算法进行了验证。

    Abstract:

    The previous paper in this series has proposed a data-diagram model for substation centralized distribution network(SCDN)to support automatic generation of single-line diagram. This paper introduces the initial layout strategy in the first stage, which focuses on a radial layout with the 10 kV bus as the center for the feeder group of SCDN for this substation. Firstly, the whole process including module design as well as graph data preprocessing are proposed. Through feeder topologic analysis, a layout planning of feeder group is worked out, and a branch-trunk layout model is proposed based on trunk-branch topographic model. On the basis of loop property study, models and calculation strategies for the loop and non-loop branch-trunk layout are put forward. Then, this paper proposes calculation methods of horizontal initial layout, target sector angle and rotation angle of single-feeder splitting diagram for SCDN, calculation method of sector jointing, and simple bonding method for virtual interconnection switch of generic switching station, which form the initial diagram of SCDN. The proposed model and methods are verified by five actual 110 kV substations.
