Simulaciones de transitorios electromagnéticos en redes eléctricas con múltiples pasos de integración a través del modelo de línea dependiente de la frecuencia (FD-Line)

Abstract

This paper develops a new extension of the frequency-dependent line model (FD-Line) for simulating power networks in parallel with multiple time steps. The main goal of this model is to achieve more efficient simulations of electromagnetic transients, produced mainly by switching operations and faults, without sacrificing its accuracy. To achieve this, the FD-Line model serves as interface between two subnetworks running at different sampling rates. Additionally, the decoupling-in-time of the FD-Line model allows splitting power networks and then, its execution in parallel.
