Abstract
A power converter control apparatus includes an automatic power controller for controlling a rectifier and an automatic reactive power controller for controlling an inverter. The inverter is coupled via DC power transmission lines to the rectifier. An output from the automatic power controller is utilized to change a control angle (or margin angle) of the inverter if a DC current flowing through the DC power transmission lines increases to exceed a rated current value of the apparatus, thereby allowing a stable power transmission.
