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 ...

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.
