Fault ride through of DC solid state transformer in medium voltage DC systems

open access: yesIET Conference Proceedings, 2023
Medium voltage direct current is emerging in distribution and collection networks and the network codes are under construction. This article introduces the MVDC network fault ride-through (FRT) requirement and the response of a DC solid state transformer is analyzed.

A DC Solid-State Transformer With DC Fault Ride-Through Capability

IEEE Journal of Emerging and Selected Topics in Power Electronics, 2022
This paper investigates a dc solid state transformer (DCSST) with dc fault ride-through (FRT) capability for medium voltage dc (MVDC) systems. The fault ride through requirement for DCSST in dc gird is investigated. Short circuit fault clearance on the medium voltage (MV) side is realized by introducing full bridge converters with cascaded dc converter

HVDC Network : DC fault ride-through improvement [PDF]

open access: yes, 2011
This paper compares the transient behaviour of two HVDC networks with similar structures but which use different converter topologies, namely two-level and H-bridge modular multilevel converters.

Fault Ride Through in DC Microgrid with Faster Recovery

IECON 2020 The 46th Annual Conference of the IEEE Industrial Electronics Society, 2020
Breaking of fault current in dc microgrid has been a challenge due to lack of dc current zero crossing. The fault current in case of pole to pole fault is high and even higher in the presence of multiple generators as all the generators feed current to the fault. This results in very high current in the faulted line. Clearing such high fault current is
