Capacitor Commutated Converters for High Power Hvdc Transmission
نویسندگان
چکیده
Two concepts for the transmission with a high power capacity using HVDC technology are analysed in this paper. The technology of Capacitor Commutated Converters (CCC) is presented and the design of two system models is described. Their steady-state as well as transient performance is presented and the CCC is compared to the conventional HVDC transmission. The advantages of the CCC for high power transmission are shown.

Experience and theoretical analysis show that the voltage and power stability becomes an important issue when high-voltage direct current (HVDC) systems using line-commutated converters (LCC) are connected to AC systems with low short-circuit capacity and that these problems become more pronounced the lower the short-circuit capacity of the connected AC system is, as compared with the rating of...

Since the implementation of the first HVDC thyristor valve at Eel River (Canada) in the early 1970’s, HVDC transmission has experienced tremendous growth. As power systems grow and become more integrated, interconnections to neighboring ac systems are becoming increasingly necessary to enhance stability, security of supply, flexibility and for other economic benefits. Primarily for stability re...
