Sensitivity analysis of a single phase to ground fault system in connection with high impedance faults: A case study

open access: yesCogent Engineering, 2020
Most of High-impedance faults (HIFs) occur due to broken conductors falling on high-resistivity desert soil in United Arab Emirates remain undetected due to incredibly low fault currents and endanger lives. A reliable detection method is needed.

Optimal power flow considering fault current level constraints and fault current limiters

open access: yesInternational Journal of Electrical Power & Energy Systems, 2014
Abstract The aim of this paper is to present a novel method to dispatch the active generation power properly in the power system while incorporating fault current levels as constraints for the optimization problem. Due to the limited capacity of protective devices such as circuit breakers, allocating active power without considering fault current ...
