变电站为中心配电网单线图(一)基于广义开闭所的图数模型

变电站为中心配电网(SCDN)是解决大规模复杂中压配电网(MVDN)态势感知可视化的一个核心概念，但作为态势底图的SCDN单线图自动生成并没有得到很好解决。重点解决支撑“数据驱动”单线图自动生成的数据-图形模型，续文提出两阶段单线图自动生成算法。首先提出广义开闭所(GS)概念，给出了GS元模型及基于GS馈线图形分裂和聚合原理，并依据配电网技术导则讨论了GS元模型的适应性；通过提出的分解方法，将MVDN分解成以高压变电站10 kV母线为主供电源、GS为互联枢纽、接入大量广义负荷的SCDN子网。其次，SCDN单馈线分裂图形通过GS节点聚合，形成可自动组装的SCDN递级图形构成模型。最后，提出适应自动布局布线、基于干线-支线拓扑模型的SCDN图形及数据模型，并进行了案例分析。为后续2篇论文的SCDN单线图自动生成提供了模型支撑。

Single-line Diagram of Substation Centralized Distribution Network Part one Diagram-Data Model Based on Generic Switching Station

Substation centralized distribution network(SCDN)is a core concept to provide a novel solution of situation awareness visualization for large-scale and complicated medium voltage distribution network(MVDN), however, the automatic generation of single-line diagram of SCDN as the background picture of situation awareness picture is not well solved. This paper focuses on the diagram-data model which supports the auto-generation of data-driven single-line diagram, and the other papers in this series will present a generation algorithm for two-stage single-line diagram. Firstly, the concept of generic switching station(GS)is put forward together with its meta model and its functions in diagram splitting, extension and bonding for SCDN feeders, which are well demonstrated with its adaptability according to technical guidelines of distribution network. By using the decomposition methods, the large-scale MVDN can be decomposed into a SCDN sub-network in which 10 kV main buses of high-voltage substation are taken as the main sources, and GSs play roles as interconnection hubs integrated with large amounts of generic loads. Secondly, with the GS node bonding of single-line splitting diagram for SCDN, hierachical diagram model of SCDN which can be assembly automated is formed. Finally, a diagram-data model suitable for automatic layout and wiring is provided based on trunk-branch topographic model, and the case analysis is made. The concepts and methods above will provide a modeling support for the automatic generation of single-line diagram, which will be presented in the followed two papers.
