Abstract Commercial Electomagnetic Transient Programs show accurate transient results by solving differential equations with respect to the circuit, but are not suitable for fast, data-based analysis. The open source distribution simulator is an open program developed for planning and analysis of the distribution system, and provides a strong linkage function with external programs and fast processing speed. In this paper, a process of modeling through an open source distribution simulator was proposed by considering the double-track parallel feeding system applied to the domestic high-speed railway system as a representative. The proposed modeling method was verified by simulating the target system under the equal conditions with a transients program and comparing the results.
Modeling and utilizing the railway system through flexible and simple text-based open software can contribute to future artificial intelligent-based analysis, or energy efficiency in terms of operational aspects.
