| Abstract: |
| The main circuit parameters are designed based on the DC transmission theory and characteristics of UHVDC transmission system for Zhundong-Sichuan ±1 100 kV UHVDC transmission project. The basic parameters of key equipments are given and the wiring scheme of two twelve-pulse converters connecting in series is suggested. Research results show that，the maximum DC operating voltage is 1 112 kV，the maximum DC is 5.357 kA，the minimum DC is 0.44 kA. The short circuit impedance of converter transformer is taken as 24 % for both ends of transmission line；the rated capacity of converter transformer at rectifier station is 542.11 MV·A and that at inverter station is 521.59 MV ·A；the transformer tap position of rectifier and inviter stations is +28／4 and +20／5 respectively；the reactive power consumption of rectifier and inverter stations is 6916Mvar and 6693Mvar respectively under rated power operation. |
