Combined control strategy of half-bridge MMC DC side fault current limiting

Combined control strategy of half-bridge MMC DC side fault current limiting

The flexible direct current (DC) grid based on modular multilevel converter (MMC) has a high current peak value and a very fast rising speed during a DC short-circuit fault. In order to limit the impact of fault current on the system in a short period of time, a fault current-limiting combined contr...
