摘要:

电力系统中的输电线路故障非局部传播,使得对由此产生的停电的控制极其困难。在这项工作中,我们建立了一个数学理论,其特征在于网络图结构的线路故障传播和本地化的模式。它提供了一个新的角度分布因素,准确地捕捉基尔霍夫定律的拓扑结构。我们的研究结果表明,传输网络的子树的特定集合的分布起着至关重要的作用,功率再分配的模式,并激励块分解的传输网络作为一种结构,以了解长距离传播的干扰。在本文的第一部分中,我们提出的情况下,当后应急网络保持连接后,初始的一组线路同时断开。在第二部分中,我们介绍了一个中断将网络分成多个孤岛的情况。

英文摘要:

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.
