一种配电网络拓扑快速增量建模方法

将配电网中的开关和T接点看作节点、将馈线段当作边,采用邻接表描述节点和边的连接关系,用从属关系反映配电变压器与边的连接关系。提出一个14列的拓扑编辑表记录编辑操作,每行反映一次编辑操作。详细描述了节点添加、节点删除、节点类型变更、边的添加和删除等基本编辑操作的处理方法,论述了拓扑变更后边与配电变压器从属关系调整方法,论述了根据拓扑编辑表进行配电网络拓扑的快速增量建模的方法,结合实例对提出的方法进行了分析和说明,结果表明提出的方法是可行的。

A fast incremental approach to distribution network modeling

Switches and taping nodes are regarded as nodes. Feeder lines are regarded as edges. The connection of nodes and edges is described by adjacent table. Distribution transformers are subordinate to the corresponding edges. A topology editing table with fourteen columns is put forward to record the editing steps. Each line of the table is a record of one editing step. The ways to add a node, eliminate a node, change the type of a node, add an edge and eliminate an edge are detailed. The method of adjusting the subordinate relationship between distribution transformers and edges is also discussed. The fast incremental modeling of distribution networks based on the topology editing table is described. A practical example is given to demonstrate the proposed method, which shows its feasibility.
