Therefore, although the back electromotive force of the capacitor can limit the fault current, the peak value of the fault current is still very high. The MMC-based VSC-HVDC system has many IGBTs and cannot withstand high short circuit fault current. So, the VSC-HVDC system needs a DCCB that can quickly isolate the short circuit fault.current protection either by limiting the fault current (called current-limiting operation) or by breaking the fault circuit after an overload timeout (called circuit-breaker operation).
