Fault-Tolerant Control of PMSM With Inter-Turn Short-Circuit Fault [PDF]

open access: yesIEEE Transactions on Energy Conversion, 2019
Fault diagnosis and fault tolerant (FT) control of electric drive systems have been extensively studied by many researchers. Naturally, one would like to use fault diagnosis information to improve FT control to achieve good post-fault performance while it is safe to do so.

Analysis and Detection of Inter-Turn Short-Circuit Fault Through Extended Self-Commissioning

open access: yesIEEE Transactions on Industry Applications, 2017
This paper presents a comprehensive analysis of permanent magnet synchronous machine stator winding impedance variation in inter-turn short-circuit and eccentricity faults. The phase impedances are monitored through an extended self-commissioning procedure at the standstill mode before or after operation, and hence are agnostic to well-known issues ...

Inter-Turn Short-Circuit Fault Ride-Through for DFIG Wind Turbines

open access: yesIFAC-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

Active power optimisation for wind farms under generator inter‐turn short‐circuit fault [PDF]

open access: yesIET Renewable Power Generation, 2020
Inter‐turn short‐circuit fault of the stator winding is one of the most common faults of asynchronous generators and often found in doubly‐fed wind turbines. The improper treatment methods will lead to unnecessary power loss or further damage to the insulation layer.
