A control device for a voltage source converter connected to a wind farm is provided. The control device includes: a power source monitor unit sensing a direct current (DC) voltage of a whole grid connected to the voltage source converter; and a control unit 20 comparing the DC voltage of the whole grid sensed with a reference voltage, wherein the control unit 20 adjusts an alternating current (AC) supplying to the wind farm to a setting when as a result of comparison, the DC voltage of the whole grid sensed is out of a preset range of reference voltages. |
