Improved Extinction Angle Control for Subsequent Commutation Failure Mitigation in LCC-HVDC
2021 IEEE 11th Annual International Conference on CYBER Technology in Automation, Control, and Intelligent Systems (CYBER), 2021Extinction angle control is one of the main control strategies to mitigate the commutation failure in HVDC, but the problem of insufficient response speed and control precision still can't be solved effectively based on the current research on measured and predictive extinction angle control.

A Novel Control Strategy for Suppression of HVDC Subsequent Commutation Failure
2020 IEEE 3rd Student Conference on Electrical Machines and Systems (SCEMS), 2020In the case of AC failures at the receiving end of the HVDC system, commutation failures are likely to occur, which may cause the converter station to lock up and seriously threaten the safety of the power grid. In order to suppress the subsequent commutation failure of HVDC, this paper studies the response of the electrical quantity and the control ...

A Novel Phase-Locked Loop for Mitigating the Subsequent Commutation Failures of LCC-HVDC Systems
IEEE Transactions on Power Delivery, 2021The AC fault ride-through and support capability of line commutated converter based high voltage direct current (LCC-HVDC) have significant influence on the safe operation of power system. The ability of phase locked loop (PLL) to synchronize with the voltage phase under AC faults would affect the recovery performance of LCC-HVDC systems.
