In this paper, a protection scheme for six-phase transmission line for series faults or open conductor fault has been presented, which initiates with the estimation of fundamental current component from the measured time-domain current signals at bus located at sending end.Abstract:
In recent times the power demand has increased considerably Power demand can be achieved by multi-phase transmission line In the present work, a protection scheme for six-phase transmission line for series faults or open conductor fault has been presented The scheme initiates with the estimation of fundamental current component from the measured time-domain current signals at bus located at sending end These signals are fed to fuzzy logic-based protection approach The proposed protection scheme has been analyzed for different types of series faults at different locations with various fault inception angles From simulation results, it is evident that the proposed fuzzy logic-based relay scheme perfectly detects and classifies all types of series faults accuratelyread more
