| Abstract: |
| The main circuit design and operation characteristics of the Zhalute-Qingzhou ±800 kV UHVDC power transmission project are simulated and analyzed. Based on the existing design methods of UHVDC projects and the characteristics of this project, the main parameters of the primary devices of the converter stations at both ends are given. The overall PSCAD simulation model of the project is established, and the operation characteristics of this system under both bipolar full voltage and bipolar 70% reduced voltage operating modes are simulated, and the results verify the correctness of the main circuit parameter design. The three-phase short circuit fault at rectifier side, two-phase short circuit fault at inverter side and converter valve short circuit fault are simulated and analyzed, and the operation characteristics of the system under faults are analyzed. The study results provide reference for the follow-up study of Zhalute-Qingzhou ±800 kV UHVDC power transmission project. |
