Independent control of active and reactive power without any needs for extra

compensating equipment.

With PWM, VSC-HVDC o® ers the possibility to control both active and reactive

power independently . While the transmitted active power is kept constant the

reactive power controller can automatically control the voltage in the ac-network.

Reactive power generation and consumption of a VSC-HVDC converter can be

used for compensating the needs of the connected network within the rating of a

converter.
