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.

Synchronous Power Control of Grid-Connected Power Converters under Asymmetrical Grid Fault [PDF]
Energies, 2017 Control of grid-connected power converters is continuously developing to meet the grid codes, according to which the generation units should keep connected to the grid and further provide ancillary services, such as voltage and frequency support ...

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 ...

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.
