Research on Fault Ride‐Through Characteristics of Inverter‐Side Hybrid HVDC in Offshore Wind Farms
IET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.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 ...

IET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.This paper first identifies the common issue across multiple LCC‐HVDC control systems, namely, that uncertain and uncoordinated control strategies switching would lead to subsequent commutation failure. Then, since power reflects variations in electrical quantities such as voltage and current, the analysis is conducted from a transmitted‐power ...

Fault Detection Algorithm for Multi-terminal LCC HVDC Interconnected Grid
IOP Conference Series: Materials Science and Engineering, 2018 The protection of Multi-terminal DC (MTDC) system is not straightforward. This paper proposes a novel protection technique for the proposed configuration topology of interconnection project between Egypt and Saudi Arabia. The proposed scheme depends on the second derivative of dc line current with the time which represents the acceleration of dc ...
