Fault Detecting and Isolating Schemes in a Low-Voltage DC Microgrid Network from a Remote Village

Energies, 2022
Fault detection and isolation are important tasks to improve the protection system of low voltage direct current (LVDC) networks. Nowadays, there are challenges related to the protection strategies in the LVDC systems. In this paper, two proposed methods

Numerical Investigation on the Dynamic Response of Fault-Crossing Tunnels under Strike-Slip Fault Creep-Slip and Subsequent Seismic Shaking

Buildings, 2023
Tunnels built in geologically active areas are prone to severe damage due to fault dislocation and subsequent earthquakes. Using the Ngong tunnel in the East African Rift Valley as an example, the dynamic response of a fault-crossing tunnel and the ...

Fault Isolation and Event Correlation for Integrated Fault Management [PDF]

, 1997
An algorithm for fault isolation and event correlation in integrated networks is presented. It reconstructs fault propagation during run-time by exploring relationships between managed objects and provides improved focus and efficiency compared to similar algorithms.
