Fault-ride Through Control Strategy of Multi-terminal High Voltage DC Systems

IFAC-PapersOnLine, 2018
Abstract A coordinate control strategy is proposed to secure fault-ride through (FRT) for voltage source converter (VSC) based multi-terminal high voltage dc transmissions (MTDC) integrating the offshore wind farms (OWFs). The short circuit fault in the ac grid obviously reduces the voltage at the connection point which, in turn, block the power ...
