论文摘要
电力系统中的传输线失败非局部传播，这使得对产生的中断的控制极为困难。在这项工作中，我们建立了一种数学理论，该理论表征了线路图结构的线路故障传播和本地化的模式。它为分布因子提供了一种新颖的看法，这些分布因素准确地捕获了基希霍夫定律的拓扑结构。我们的结果表明，传输网络子树的特定集合的分布在功率重新分布的模式上起着至关重要的作用，并激发了传输网络的块分解，作为一种结构，以了解扰动的长距离传播。在本文的第一部分中，我们介绍了宿舍后网络同时断开一组线路后保持连接的情况。在第二部分中，我们介绍了断电将网络分为多个岛屿的情况。
Transmission line failures in power systems propagate non-locally, making the control of the resulting outages extremely difficult. In this work, we establish a mathematical theory that characterizes the patterns of line failure propagation and localization in terms of network graph structure. It provides a novel perspective on distribution factors that precisely captures Kirchhoff's Law in terms of topological structures. Our results show that the distribution of specific collections of subtrees of the transmission network plays a critical role on the patterns of power redistribution, and motivates the block decomposition of the transmission network as a structure to understand long-distance propagation of disturbances. In Part I of this paper, we present the case when the post-contingency network remains connected after an initial set of lines are disconnected simultaneously. In Part II, we present the case when an outage separates the network into multiple islands.
