| 摘 要： | 提出了一种采用图论的故障影响遍历的配电网可靠性评估方法。算法根据故障枚举的思想，通过搜索故障影响的开关状态，将配电网的可靠性评估问题转化为一个图论中的连通性问题，并利用遍历技术将结果保存到故障影响矩阵中，由故障影响矩阵计算得到最终的可靠性评估结果。应用该算法对IEEERBTS—BUS2系统进行可靠性评估，验证了该算法的正确性和有效性。该算法能有效地考虑配电系统的各种网络拓扑结构，是一种较为实用的可靠性评估算法。 |

| Abstract: | A fault traversing algorithm for reliability evaluation of radial distribution system was given by using the graph theory. The algorithm, based on fault enumeration thoughts, transforms the reliability evaluation of distri- bution system into a graph theory connectedness problem through the reverse search of fault influence, and saves the traverse results were to a fault influence matrix. The reliability evaluation results were calculated by the fault influ- ence matrix. The example shows that this algorithm can effectively consider the various kinds of network topology and is a more practical reliability evaluation algorithm. |
