Three-Phase Frequency-Dependent Network Equivalents in the ATP for Lumped Parameter Systems Using Descriptor Formulation, Rational Models, and Symmetrical Component Data

The use of frequency-dependent network equivalents (FDNEs) is of fundamental importance to carry out electromagnetic transient studies in large-scale power systems, regarding high precision and acceptable computation time. Therefore, this paper proposes a methodology to build three-phase equivalents...

Description
Summary:The use of frequency-dependent network equivalents (FDNEs) is of fundamental importance to carry out electromagnetic transient studies in large-scale power systems, regarding high precision and acceptable computation time. Therefore, this paper proposes a methodology to build three-phase equivalents using descriptor system formulation, rational models, and symmetric component data in the ATP (Alternative Transients Program). The proposal is a generalization of the method presented in Campello et al. (Electr Power Syst Res 178:106029, 2020) to build multiport FDNEs only for positive sequence.
