Numerical modeling of HTS excited medium‐speed wind generators with diode rectifier stator feeding

open access: yesInternational Journal of Numerical Modelling: Electronic Networks, Devices and Fields, Volume 37, Issue 5, September/October 2024.
Abstract Medium‐speed wind generators in the MW‐range with high‐temperature superconducting excitation winding are analyzed by means of non‐linear 2D and 3D FEM models. Besides an inverter‐based sinusoidal stator current feeding, a grid connection via a diode rectifier is analyzed by using coupled FEM and circuit simulations.

Design of 20 MW direct‐drive permanent magnet synchronous generators for wind turbines based on constrained many‐objective optimization

open access: yesWind Energy, Volume 27, Issue 9, Page 847-872, September 2024.
Abstract This study introduces a constrained many‐objective optimization approach for the optimal design of 20 MW direct drive (DD) permanent magnet synchronous generators (PMSGs). Designing a high‐performance, competitive DD‐PMSG requires considering the generator's performance as well as its weight and material cost.

Analysis of hybrid AC/DC transmission system: A Turkey case study

open access: yesIET Generation, Transmission &Distribution, Volume 18, Issue 18, Page 3017-3028, September 2024.
This study aims to increase the transmission capacity without experiencing right‐of‐way problems by converting Turkey's existing high voltage AC systems to hybrid AC/DC systems. With such a design, the variation of the electric and magnetic fields that will occur has also been analysed by 2D modelling in FEMM4.2.
