Fault-Tree Analysis for Power Gird Emergency Logistics System under Large-Scale Natural Disaster

Abstract:

Power grid, one of the critical infrastructures, is a vital component of the world’s energy supply. Once large-scale natural disaster occurs, it is inevitable to meet unexpected faults on emergency logistic. Fault-tree analysis (FTA) is a risk estimation tool to describe and model causal interactions and logical relationships between undesired events in a system Taking uncertain situation and response failure into consideration, this paper proposed a fault-tree analysis on PG-ELS with fuzzy probabilistic confidence. The most critical failure mode is identified using the ranking method based on interval number.
