IRACHETA-CORTEZ, Reynaldo. Simulation of Electromagnetic Transients in Power Networks with Multiple Time Steps with the Frequency-Dependent Line Model (FD-Line). Ing. invest. y tecnol. [online]. 2015, vol.16, n.1, pp.13-24. ISSN 2594-0732.

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 sub-networks 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.

Keywords : multi-rate simulations; FD-Line model; digital signal processing; low-pass filters; time domain; power systems.
