Unidirectional HVdc Topology With DC Fault Ride-Through Capability

open access: yesCanadian Journal of Electrical and Computer Engineering, 2017
HVdc transmission using modular multilevel converters (MMCs) is becoming increasingly prevalent. However, line-commutated converter (LCC) HVdc transmission remains advantageous in its ability to clear dc faults and restart power transmission without operation of the ac system protection. This paper presents an HVdc system topology that employs both MMC
