Research on Fault Ride‐Through Characteristics of Inverter‐Side Hybrid HVDC in Offshore Wind Farms
This paper addresses issues in wind power DC transmission systems, such as difficulty in maintaining power delivery during rectifier‐side faults and frequent overvoltage occurrences during inverter‐side faults. A hybrid topology comprising a rectifier‐side MMC and an inverter‐side LCC‐MMC configuration is proposed, along with corresponding enhanced ...
