Zero-Sequence Current Elimination Strategy Based on Frequency-Adaptive Repetitive Control of OW Machines During Leg-Sharing Post-Fault Operation

Abstract: Existing zero-sequence current (ZSC) elimination methods have unsatisfactory elimination performance during post-fault (PF) operation due to unequal dead time effects on the terminals of the ...
