Abstract :
The capacitor commutated HVDC converter (CCC) is evaluated using steady-state as well as transient analysis. The steady-state analysis indicates that the CCC device is superior to the conventional converter when operating into very weak AC-networks. This is also confirmed by electromagnetic transient simulation. However, transient simulation shows that the CCC´s performance is poorer than its conventional counterpart when recovering from unbalanced disturbances such as single-phase faults.
