630 kV, 60 Hz of AC voltage is fed to the HVDC converter from the secondary transmission transformer. Due to safety reasons, the converter is permitted to adopt delayed firing angles in the range of 5 to 70 degrees only. The active power and current at the DC link must maintain at 541 MW and 0.83 kA, respectively. Thus, what firing angle should be fired to the converter's switching so that the DC link can maintain that power transfer? Justify your answer. Then, determine the power factor of the converter.
