网络分裂对连锁故障过程的影响

The impact of a network split on cascading failure processes

Fiona Sloothaak, Sem C. Borst, Bert Zwart

摘要:

级联故障模型通常用于捕获故障可能连续触发进一步故障的现象,从而导致连锁效应。在许多网络中,这最终会导致一个分裂的网络,其中故障传播在各个组件之间独立地继续。为了深入了解网络分裂对级联故障过程的影响,我们扩展了一个行之有效的级联故障模型,故障的数量服从幂律分布。我们假设单个线路故障立即将网络分成两个部分,并检查其对幂律指数的影响。结果提供了有价值的定性见解,这是了解更复杂的网络拆分场景的关键第一步。

英文摘要:

Cascading failure models are typically used to capture the phenomenon where failures possibly trigger further failures in succession, causing knock-on effects. In many networks this ultimately leads to a disintegrated network where the failure propagation continues independently across the various components. In order to gain insight in the impact of network splitting on cascading failure processes, we extend a well-established cascading failure model for which the number of failures obeys a power-law distribution. We assume that a single line failure immediately splits the network in two components, and examine its effect on the power-law exponent. The results provide valuable qualitative insights that are crucial first steps towards understanding more complex network splitting scenarios.
