Study of Branching of Ultra Long Distance HVDC Transmission Lines with Line – Commutated Converters
(0) The purpose of this paper is to show a possibility of branching of ultra long distance HVDC power transmission to Japan. The authors have examined a power flow and a transient response caused by the ground faults to reveal characteristics of the system with line-commutated converters, where three kinds of the HVDC transmission lines are TACSR 810 mm2, TACSR 1160 mm2 and TACSR 1520 mm2. The following results have been obtained. (1) The calculations have shown that the overall efficiency becomes 96 to 98 ％ under the condition of DC voltage of 800 kV. (2) The converters can stably supply the output active power after the ground fault. The results indicate the possibility of branching of ultra long distance HVDC transmission. The authors also have examined the optimum rating of inverters.
