An efficient deep learning based scheme for adaptive auto-reclosing in power transmission lines

Alexandria Engineering Journal
As 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.

Estimation of Current Distribution in the Electric Railway System in the EMTP-RV

, 2017
Current distribution is important for the electromagnetic compatibility and electromagnetic fields calculations. The current value directly determines the magnetic field and consequently coupling of the systems. The return current has an opposite direction of supply current and decreases coupling and interferences.

Investigation of the Centrifugal Force Effect to a Revolving Vane (RV) Machine

, 2012
The Revolving Vane (RV) machine is unique because the cylinder rotates together with the rotor at their respective axis. This causes various unique behaviors that are not previously observed in the conventional rotary machines. In this paper, the effects

Primary Frequency Reserve Providing Strategy of Doubly-Fed Induction Generator Wind Generation Using Rotor Inertia Characteristics

IEEE Access
For power grids with a high penetration level of wind power generation, stochastic wind speed variation adversely affects the frequency stability. A variable-speed wind turbine generator would deloads its output by shifting the power operating point to ...
