Capacitor commutated converters for HVDC systems

Abstract

HVDC 2000 is the name given by ABB to a new generation of high-voltage DC power transmission systems based on the capacitor commutated converter, or CCC. The concept, which has been mainly of academic interest for many years, has now become reality on account of numerous special features offered by the CCC. Capacitor commutated converters perform better than conventional converters and are less sensitive to AC system disturbances.
