Adaptive faulted phase selection for lines connecting converter-based sources [PDF]
IET Conference Proceedings, 2022 Renewable sources with numerous converter-control operations introduce dynamic fault signatures in the network. Such nonhomogeneous situations result in maloperation of available phase selection methods at times, which may further lead to incorrect protection decisions and affect system resilience.
