Dc fault current calculation method in MMC-HVDC grid considering current-limiting devices

This paper proposes a DC fault current calculation method to reveal the fault current evolution mechanism of the modular multilevel converter (MMC)-based HVDC grid. The new method includes the fast switching of the current-limiting devices and the transient characteristics of the metal oxide arreste...
