Coordination Control Strategy for Compound Fault of MMC-HVDC [PDF]
MATEC Web of Conferences, 2016 Single-line to ground fault of DC side and sub-module fault are typical faults of MMC-HVDC. When each of the above faults occurs, the system will give a signal for circuit-breaker releasing, this will result in interruption of power delivery, the stability of the system is greatly reduced. When these two faults occur simultaneously, research on control

Start Control for the MMC-HVDC
IOP Conference Series: Materials Science and Engineering, 2019 Abstract This paper designs the control strategies and start procedure of MMC-HVDC. The start procedure consists of three stages, uncontrollable charging stage, controllable charging stage and power-raising stage. The current circuit is analysed and the equivalent circuit is obtained in uncontrolled charging stage.
