复杂配电网的供电可靠性定量评估

为了快速而有效地分析配电网中可能出现的各种故障所产生的后果，提出了一种能较准确进行复杂配电网供电可靠性定量评估的故障遍历算法．该算法引入了数据结构中的深度优先搜索、广度优先搜索以及邻接表的概念．其中：将深度优先搜索方法用于搜寻故障失电区域以及可操作和不可操作恢复供电区域；用广度优先搜索方法寻找对非故障区恢复供电后潮流可能发生变化的线路；用基于邻接表的“前推后代”潮流算法校验供电恢复路径是否可行．算例分析表明，本文的方法能适用于对复杂配电网供电可靠性进行定量评估．

The Quantitative Evaluation of Complex Distribution System Reliability

A new reliability der to quickly and effective distribution system. This evaluation algorithm for complex radial distribution system was proposed in orly analyze the sequent caused by different accidents that maybe happen in the algorithm introduces the conceptions of Depth_First Search, Breadth_First Search and Adjacency List in data structure. The conception of Depth_First Search is used to search the power cut area and the restoration through operation, unstorable area. The conception of Breadth_First Search is used to search the lines that power flow maybe changes when the restoration is powered. The back/forward sweep distribution power flow algorithm based on adjacency list is used to checkout the feasibility of the restore path. The example verifies that the algorithm is applicable to evaluate the complex radial distribution system .
