After the occurrence of a DC-side feeder faults on HVDC transmission systems, protection
and fault detection systems are anticipated to minimize their onerous effects, by initiating …

Multi-terminal HVDC grids facilitate the integration of various renewable resources from
distant locations; in addition, they enhance the reliability and stability of the grid. Protection …

High-voltage direct-current (HVDC) power transmission is becoming increasingly important
due to steadily rising need for bulk power delivery and interconnected power transmission …

DC fault protection is a major issue in multiterminal high-voltage DC current transmission
systems. Most studies have focused on primary protection, which considers a different …

The primary protection speed requirement for the HVDC grid is much faster as compared to
the conventional HVAC grid. This research article proposes a travelling wave-based primary …

As the primary protection and control device in direct current (DC) power systems, DC circuit
breakers (DCBs) have complex structures and numerous components, making it prone to …

HVDC transmission system has been becoming an alternating approach to AC transmission
