VSC- based HVDC System Capability to Ride Through Faults

Abstract

VSC-HVDC is becoming an increasingly attractive technology for power network development. In order to establish itself a viable alternative it still has to address some issues, e.g., its response under fault situations on both AC and DC side. This paper makes a state-of-the-art review on how different converter topologies affect the Fault Ride Through (FRT) ability of the system. By comparing the different converter topologies, it is possible to underline the features that will be able to guarantee a successful FRT, which can be very helpful in order to choose the most suitable converter topology for different applications.
