An efficient deep learning based scheme for adaptive auto-reclosing in power transmission lines
Alexandria Engineering JournalAs a large percentage of faults in transmission lines are single-line-to-ground (SLG) and transient in nature, the use of adaptive single-phase auto-reclosing (ASPAR) schemes is essential.

IET Renewable Power Generation, Volume 19, Issue 1, January/December 2025.This paper proposes an optimised power dispatching method for a wind farm (WF) during a de‐loading operation. The WF control centre collects wind speed information of each wind turbine and creates several groups, including wind turbines with similar wind speeds.

Engineering and Technology JournalNatural Lightning strikes are the main cause of over voltages in the power system. Such lightning over voltages can damage the system insulation if sufficient protections are not provided to the system. In the power system ground wire or shield wires are placed on top of the transmission line tower for the protection of transmission lines against ...
