Ferromagnetically Shielded Fault Current Limiter (FS‐FCL) Evaluation in Power Line

IET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.
This study introduces a new ferromagnetically shielded FS‐FCL design and its control strategy for limiting and interrupting fault currents. The fully shielded core structure enhances inductance and prevents saturation, enabling an immediate fault response without causing voltage drop during normal conditions.

Stability and Synchronization of MMC‐HVDC Systems Using SRF and Inertia‐Based PLLs

IET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.
This study investigates the influence of synchronous reference frame PLL (SRF‐PLL) and the inertia PLL (IPLL) on the stability of grid‐connected modular multilevel converter high voltage direct current (MMC‐HVDC) systems. The findings highlight intrinsic stability limitations of PLL‐based systems, offering insights toward more stable, PLL‐less ...

Dead-time effect modeling for hybrid modular multilevel converter using twin mapping

International Journal of Electrical Power & Energy Systems
Dead-time control is essential for modular multilevel converters (MMCs), but it negatively impacts MMC performance. To support the development of control strategies to mitigate the adverse effects of dead-time, electromagnetic transient (EMT) simulations

Analysis of a Three Phase Induction Motor Directly from Maxwell's Equations

, 2011
The torque developed in a three phase AC squirrel cage motor is usually expressed in terms of resistances and reactances of the stator, the rotor, and the motor as a whole. We use Maxwell's equations to find the torque in terms of geometrical parameters.

Total Distortion—A New Power Quality Index on Current Harmonic Evaluation for Users With Internal Loads and DERs

IET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.
ABSTRACT The IEEE Std 519–2022 IEEE Standard for harmonic control in electric power systems is widely used for controlling the harmonics in the electric power system. It uses the total demand distortion (TDD) for current harmonic evaluation at the point of common coupling (PCC).
