Fault Current Characteristics of the DFIG under Asymmetrical Fault Conditions [PDF]
Energies, 2015 During non-severe fault conditions, crowbar protection is not activated and the rotor windings of a doubly-fed induction generator (DFIG) are excited by the AC/DC/AC converter.

Improved DFIG Capability during Asymmetrical Grid Faults [PDF]
IECON 2015 - 41st Annual Conference of the IEEE Industrial Electronics Society, 2015 In the wind power application, different asymmetrical types of the grid fault can be categorized after the Y/d transformer, and the positive and negative components of a single-phase fault, phase-to-phase fault, and two-phase fault can be summarized. Due

Active fault tolerant control for twin wind turbine subject to asymmetric fault [PDF]
2021 International Conference on Control, Automation and Diagnosis (ICCAD), 2021 This paper addresses the problem of control of a twin wind turbine which is subject to an electrical fault affecting only one stator phase of one turbine. An active fault tolerant control is proposed. The performance and robustness of the proposed control, comparing to a passive fault tolerant one developed in the literature, are shown through ...

Assessing Asymmetric Fault-Tolerant Software [PDF]
2010 IEEE 21st International Symposium on Software Reliability Engineering, 2010 The most popular forms of fault tolerance against design faults use "asymmetric" architectures in which a "primary" part performs the computation and a "secondary" part is in charge of detecting errors and performing some kind of error processing and recovery. In contrast, the most studied forms of software fault tolerance are "symmetric" ones, e.g.

Submodule fault-tolerant control based adaptive carrier-PDPWM for modular multilevel converters
Energy Reports, 2021 The modular multilevel converter (MMC) is considered a very promising candidate for medium-voltage and/or high-power grids. One of the major concerns in half-bridge MMCs, especially with large number of levels, is the fault occurs at the converter ...

Assessment of a Universal Reconfiguration-less Control Approach in Open-Phase Fault Operation for Multiphase Drives [PDF]
, 2019 Multiphase drives have been important in particular industry applications where reliability is a desired goal. The main reason for this is their inherent fault tolerance. Di erent nonlinear controllers that do not include modulation stages, like direct
