Successful deployment of High-Voltage Direct Current (HVDC) grids necessitates effective DC fault handling strategies, which can minimize the severe consequences caused by DC faults on the AC and DC side of the HVDC grids. Therefore, this paper inves

Speed and selectivity of DC fault protection are critical for High-Voltage DC (HVDC) grids and present significant technical and economic challenges. Therefore, this paper proposes a non-unit protection solution that detects and discriminates DC faul

This article presents a new method for locating faults along feeders in a direct current (dc) microgrid using a multiple capacitive earthing scheme. During fault conditions, capacitors within the earthing scheme are charging by transient currents tha

Owing to the fact that travelling wave propagation in an HVDC grid is a heavily frequency dependent phenomenon, frequency domain analysis has been identified as a useful means of assessing the capabilities and limitations of non-unit protection. This
