Analysis of faulted power systems in three phase coordinates - a generic approach

Analysis of faulted power systems in 3-phase coordinates is desirable when dealing with unbalanced networks and complex faults. Thevenin's model in 3-phase domain is well-known for shunt faults. However, lack of generic circuit model for series and simultaneous faults is an impediment, as it sacrifices both simplicity and computational efficiency. In this paper, we extend this approach to arbitrarily complex faults. Case studies with complex faults on two example systems demonstrate the claims made in the paper
