| 摘 要： | 基于PSCAD/EMTDC仿真软件建立含H-HVDC的多馈入高压直流输电子系统,研究传统多馈入高压直流输电子系统、含VSC-HVDC的多馈入输电子系统和含H-HVDC的多馈入输电子系统的暂态运行特性.仿真结果表明:与传统多馈入高压直流输电子系统和含VSC-HVDC的多馈入高压直流输电子系统相比,含H-HVDC的多馈入高压直流输电子系统在抵御换相失败、抑制暂态过电压、减少故障恢复时间等方面具有明显优势.

| Abstract: | The subsystem with H-HVDC for the multi-infeed HVDC system was established based on the PSCAD/EMTDC simulation software in this paper.The transient operating characteristics of the multi-infeed subsystem for the traditional HVDC transmission system, the multi-infeed transmission subsystem with VSC-HVDC and the multi-infeed transmission subsystem with H-HVDC were studied.The simulation results showed that compared with the traditional multi-infeed HVDC transmission subsystem and the multi-infeed HVDC transmission subsystem with VSC-HVDC, the multi-infeed HVDC transmission subsystem containing H-HVDC had obvious advantages in suppressing commutation failure, restraining transient over voltage and shortening the time of the fault recovery. |
