Protection Principle of DC Line Based on Fault Component of Line Mode Voltage with Current-Limiting Reactor

High-resistance faults on the DC lines of multi-terminal VSC-HVDC grids lead to insufficient protection reliability, and the introduction of current-limiting strategies alters the system’s intrinsic fault characteristics, degrading protection performance. To address these issues, we propose a DC-lin...
