One of the most challenging points in the simulation of power system transients is the modeling of frequency dependent impedances or admittances and their inclusion in the simulation environment. Highly accurate models can be identified via rational function approximations in the frequency domain, for instance by Vector Fitting. One way of including the(More)
After a severe disturbance due to an insulation failure in a transmission line, the precise fault location is a critical problem for the maintenance crew. In order to avoid further economical and social costs, fault diagnosis has to be performed as soon as possible. Fault diagnosis has been a major area of investigation among power system problems and(More)
