| 摘 要： | 为从根本上改善最小断点集（minimum break point set，MBPS）适应系统结构非预设性变化的水平，提出多区域复杂环网最小断点集求取及更新算法。在静态网络拓扑情况下，利用保护关联矩阵并行计算各子区域的最小断点集，在此基础上，优化计算主区域的最小断点集，并据此确定全州最小断点集。在网络变结构的情况下，基于广义断点集提出单区域最小断点集更新方案，并将其推广至多区域网络，存主区域、子区域及单线路联络节点发生变结构情况下，快速更新最小断点集。典型的5区域68节点系统计算结果表明：该方法在最小断点集求取方面，不但能够保证全网断点数目合理，还能提高最小断点集的计算速度；在最小断点集更新方面，该方法仅需处理变结构所关联区域的最小断点集，即可实现全网最小断点集更新，有效地降低了复杂环网最小断点集更新的复杂性，计算量小，适用于多种网络变结构情况。

| Abstract: | In order to basically improve the minimum break point set(MBPS) to adapt to the non-predictive change level of system structure,a novel scheme of calculating and updating the MBPS for multi-area complex loop network was proposed in this paper.According to static network topology,the MBPSs of sub-area are parallel calculated based on the relay-incidence matrix.Then,the optimization calculation for the MBPS of main-area is calculated and the final MBPS of the whole network is obtained.When the network topolog... |
