| 摘要: |
| 快速、准确和全面地辨识关键线路对预防连锁故障、保障电网安全稳定运行具有重要意义。提出一种基于源流路径链和输电介数的电网关键线路辨识方法，该方法首先建立电网有向加权拓扑模型，然后基于源流路径链生成算法，搜索源流节点对间的所有潮流传输路径。根据输电介数的定义，计算各线路的输电介数并排序，按照排序结果辨识电网关键线路。最后，通过对IEEE39节点的算例测试，验证了所提算法的有效性和准确性。 |

| Abstract: |
| Fast, accurate and comprehensive identification of the critical lines is important for preventing cascading failures and guaranteeing security and stability operation of grid. An identification method of the key lines in grid based on path chains and transmission betweenness is proposed, which firstly establishes an directed and weighted topological model, and then searches for power transmission path between sources and flows based on path chains generation. The transmission betweenness value of each line is calculated and sorted according to the definition of transmission betweenness and the critical lines are identified according to the sorting results. Finally, the analysis results of IEEE-39 verify the validity and accuracy of the proposed algorithm. |
