Abstract [en]

This paper investigates the replacement of Rotary Frequency Converters(RFCs) with Static Frequency Converters (SFCs) in the Swedish synchronous-synchronous Railway Power Supply System (RPSS) operating at1623Hz. Thereis a need to investigate how such a system behaves when RFCs are partly replacedwith SFCs, as the SFCs do not have any physical inertia.Most of the transient stability studies published for synchronous-synchronousRPSS address the behaviour of a single RFC or SFC against an infinite bus.However, there are very few studies investigating a system with several RFCs,SFCs or a mix of both in the same converter station. This paper presents the resultsof a transient stability study with both RFCs and SFCs. The investigated casesconsist of faults at different locations, and present the results when an RFC isreplaced with an SFC in a converter station.
