Abstract

This paper describes a capacitor commutated converter (CCC) model suitable for power flow and transient stability studies. The CCC control structure and important operational details are described. The practical advantages of the CCC as compared to the conventional HVDC converter are discussed. Results are presented for power flow, power system stability, small signal analysis and control design studies. These results clearly demonstrate the superior performance of a CCC link, when connected to a very weak AC system
