A Rotor Voltage Compensation Method for Transient Voltage Dip in Grid‐Connected Power Systems With A High Proportion of Renewable Energy Under Ramp‐Type Gradual Disturbance

Engineering Reports, Volume 8, Issue 3, March 2026.
This paper proposes a doubly fed induction generator rotor voltage compensation control to address transient voltage dips in renewable‐rich grids. By compensating for rotor electromotive forces, it suppresses current fluctuations and surges during asymmetrical faults.

Time‐Domain Geoelectrical Modeling and Experimental Validation of Ground Potential Rise in Multilayer Soil Structures during Fault Events

Energy Science &Engineering, Volume 14, Issue 3, Page 1492-1504, March 2026.
This study develops a time‐domain geoelectrical model of ground potential rise (GPR) in multilayer soil that couples electromagnetic field theory with nonlinear fault arc resistance. Finite‐element simulations calibrated against scaled fault‐injection experiments reproduce measured GPR and step/touch voltages within 4.7% error, revealing that steady ...

Experimental verification of an angle-sensorless control scheme for bearingless permanent magnet machines

Mechanical Engineering Journal, 2017
Bearingless machines are used for a variety of applications with demand for low mechanical loss, low wear and low contamination. These machines use contact-free magnetic suspension to levitate the rotor. The control of the machine requires precise radial

Accretion Disks and Dynamos: Toward a Unified Mean Field Theory

, 2012
Conversion of gravitational energy into radiation in accretion discs and the origin of large scale magnetic fields in astrophysical rotators have often been distinct topics of research. In semi-analytic work on both problems it has been useful to presume
