摘要
为快速适应配电网重构导致的拓扑结构改变和潮流方向不确定性,提出了一种配电网结构划分方法。按图论中出度的定义,将配电网划分成支链结构,并建立支链邻接表。采用深度优先遍历法,确定邻接表前推回代顺序,得到初始潮流计算结果。利用支链结构特点,消除侧边影响,快速形成单环网。解环时,能够快速生成新的支链并确定其前推回代顺序。算例结果验证了该方法的快速性和有效性。
In this paper,a dividing method for the structure of distribution network has been proposed to rapidly adapt to the variation of the topology and the uncertainty of tide direction caused by network reconfiguration. Based on the definition of out-degree in graph theory,the network has been divided into several branch chains,and the branch chain adjacency list has been set up. The initial results of the power calculation and the back / forward sweep sequence are confirmed by the characteristics of the depth first search. The single-ring network has been set up by the feature of the branch chain structure as it eliminates the effects of the laterals. When the single-ring is dissolved,it helps to redistrict the new branch chain and ascertain its back/forward sweep sequence. The results of the calculation example indicate that the method being proposed is fast and effective.
