This paper is aimed to present a model, implemented through the Simulink software of Matlab, designed to simulate the behavior of the high-speed circuit breaker during the process of extinguishing a short-circuit current in DC power supply systems. In addition, the representative models of an electrical substation, of the contact line and of the track are presented, to apply the circuit-breaker model for the extinction of short-circuit phenomena at certain points of the power supply system of a railway line or trolleybus.

Abstract
This paper is aimed to present a model, implemented through the Simulink software of Matlab, designed to simulate the behavior of the high-speed circuit breaker during the process of extinguishing a short-circuit current in DC power supply systems. In addition, the representative models of an electrical substation, of the contact line and of the track are presented, to apply the circuit-breaker model for the extinction of short-circuit phenomena at certain points of the power supply system of a railway line or trolleybus.File in questo prodotto:
