| 摘 要： | 复杂配电网进行可靠性评估时,通常采取对网络进行分区分块或等值法简化网络,但对不同配电网中的多种类型开关处理较为复杂.为快速准确地评估复杂配电网络的可靠性,提出一种基于索引搜索算法的配电网可靠性评估方法,无需网络化简.通过设计高效率的搜索方法实现了复杂的故障模式后果分析.算例结果表明,该法计算量小,可靠性指标准确度较高,且对多种配电网结构具有通用性.

| Abstract: | Network partition method or network equivalent method is usually used to simplify the network structure for evaluating reliability of complex distribution system. But these methods are complicated for analysis of various types of switches in different distribution system. Aiming at accurate and fast evaluation reliability of complex distribution system, a method based on index search algorithm is proposed, which does not need network simplification. A high efficiency search method is designed to realize consequence analysis of complex failure mode. Example results show that the proposed method can reduce computation cost and improve the accuracy of reliability indices; it has universality for multiple distribution system structure. |
