Detection and Localization of Rotor Winding Inter-Turn Short Circuit Fault in DFIG Using Zero-Sequence Current Component Under Variable Operating Conditions. [PDF]
Sensors (Basel)DFIG rotor windings face high stress and transients from back-to-back converters, causing inter-turn short circuit (ITSC) faults. Rapid rotor-side dynamics, combined with the unique capability of DFIG to operate in multiple modes, make the fault ...

Inter‐turn short‐circuit effect on induction machine iron losses [PDF]
COMPEL - The international journal for computation and mathematics in electrical and electronic engineering, 2010 PurposeThe aim of this paper is to estimate the iron losses for an induction machine in the healthy case taking the slotting effect into account and to study the effect of an inter‐turn short‐circuit on these losses. Theoretical results are then compared with experimental ones.Design/methodology/approachA simple analytical model of iron losses allows ...

Inter-Turn Short-Circuit Fault Ride-Through for DFIG Wind Turbines
IFAC-PapersOnLine, 2020 Inter-Turn Short-Circuit (ITSC) of the stator winding is one of the most common faults in asynchronous generators. A significant feature of ITSC is the increase of the current in the faulty phase. Improper treatment may lead to unnecessary power loss or further deterioration. Therefore, this paper proposes a fault ride-through strategy under the stator
