VSC- based HVDC System Capability to Ride Through Faults

RE&PQJ
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 (
