Dynamic reactive power characteristic analysis of inverters under the commutation failure faults in HVDC systems

In the traditional high voltage direct current (HVDC) systems, commutation failure (CF) fault is one major challenge, and the transient var characteristic of the inverter station is an essential factor in the counter measures against CF fault. Based on the detailed switching process of valves during...
