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.

The structure and composition of exhumed faults, and their implications for seismic processes [PDF]
, 2000 Field studies of faults exhumed from seismogenic depths provide useful data to constrain seismologic models of fault zone processes and properties. Data collected on the San Andreas Fault in the San Gabriel Mountains has shown that large-displacement ...

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 ...

Localising imbalance faults in rotating machinery [PDF]
, 2013 This thesis presents a novel method of locating imbalance faults in rotating machinery through the study of bearing nonlinearities. Localisation in this work is presented as determining which discs/segments of a complex machine are affected with an ...

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.

Identification and location method of asymmetric faults in coal mine power network
Gong-kuang zidonghua, 2018 Three asymmetrical faults of singe-phase grounding, singe-phase line breakage and ferroresonance in coal mine power network are easily misjudged, and existing methods hardly identify the three faults correctly.

Memory Fault Simulator for Static-Linked Faults [PDF]
, 2006 Static linked faults are considered an interesting class of memory faults. Their capability of influencing the behavior of other faults causes the hiding of the fault effect and makes test algorithm design and validation a very complex task.

Fault coordination control for converter-interfaced sources compatible with differential protection during asymmetrical faults [PDF]
Energy Reports, 2022 Converter-interfaced renewable energy sources (CIRESs) may have a different fault current angle with synchronous generators (SGs), so the large angle difference on both sides will cause low sensitivity or failure for traditional proportional braking differential protection. So as to cope with this issue, a new fault control strategy is put forward.
