Fault-current handling capability of the modular multilevel converters (MMCs) under dc-
cable short-circuit conditions is a major concern for the MMC applications on the high …

The change rate of the dc reactor voltage with predefined protection voltage thresholds is
proposed to provide fast and accurate dc fault detection in a meshed multiterminal HVDC …

With the capacity of new energy resources such as wind power and photovoltaic in
Zhangbei region increasing rapidly, the reliable transmission and consumption capabilities …

DC line faults are major issues for a multiterminal high-voltage direct current (HVDC) system
based on voltage-source converter (VSC). The fault current increases quickly along with a …

This paper proposes a generic pole-to-pole short-circuit fault current calculation method for
dc grids. The calculation procedure begins from the simplified RLC equivalent model of a …

The extensive application of power transfer through high-voltage direct current (HVDC)
transmission links in smart grid scenarios is due to many factors such as high-power transfer …

This paper provides a detailed analysis of the temporal development of fault currents in a
multiterminal high-voltage direct-current (MT-HVDC) grid composed of a bipolar converter …

The fast dc line protection is one of the key techniques for the multi-terminal flexible dc grid
whose main technical difficulty lies in quick and reliable fault identification. The traditional …

DC fault current limitation is important for the low-voltage dc distribution network, because
the existing dc selective protection cannot act fast enough. However, the typical dc fault …

To ensure the continuous operation of the voltage source converter based multi-terminal
HVDC system (VSC-MTDC), there has been much concern regarding how to isolate the …
