The large shunt capacitances on both sides of VSC-HVDC transmission line will block and reflect the travelling waves when a fault occurs on DC cable lines. When a forward fault occurs, the protection will detect the arrival of forward and backward tr

Due to the labyrinthine topology of the MMC-MVDC system, identification of the faulty feeder especially for a single-pole-to-ground (SPTG) fault is a challenging task. Based on the characteristics analysis of capacitance charge–discharge, this arti

Nowadays, the efficient and reliable protection and location schemes for MMC-MVDC (Modular Multilevel Converter-Medium Voltage Direct Current) grid are few. This paper is the first to propose a scheme to not only protect the feeders and the busbar, b

This paper presents a novel pilot protection scheme of DC cable line in voltage-source-converter (VSC) based multi-terminal DC (MTDC) grids, which utilizes a novel phase-mode transformation to decouple the bipolar DC cable current into six mode and i

As a modular multilevel converter-based medium-voltage direct current (MMC-MVDC) distribution grid mostly utilises small current grounding modes, the weak fault current for single-pole-to-ground (SPTG) fault is very difficult to detect especially in

This paper proposes a novel directional pilot protection for VSC-MTDC frequency-varying cable lines. Based on a new phase-mode transformation to decouple the bipolar DC cable, this paper utilizes the propagation time difference between 6-th mode forw
