Utilizing Active Rotor-Current References for Smooth Grid Connection of a DFIG-Based Wind-Power System

open access: yesAdvances in Electrical and Computer Engineering, 2020
Large inrush currents emerge abruptly whenever a doubly fed induction generator (DFIG) attempts to connect with the grid. Moreover, a DFIG is highly vulnerable to grid disturbances owing to its direct stator-grid contact, which induces a sizable ...

Magnetic monitoring of power generators in EPS [PDF]

open access: yesZbornik Radova: Elektrotehnički Institut "Nikola Tesla", 2011
Shorted turns are the result of failed insulation between individual windings in generator rotors. The use of air-gap magnetic flux probes has proven effective in the detection of generator rotor winding shorted turns. Analysis of air-gap flux probe data

Recovery of transversely-isotropic elastic material parameters in induction motor rotors

open access: yesJournal of Mathematics in Industry
We propose numerical algorithms for recovering parameters in eigenvalue problems for linear elasticity of transversely isotropic materials. Specifically, the algorithms are used to recover the elastic constants of a rotor core.
