Suppression of continuous commutation failure in LCC-HVDC transmission based on improved virtual synchronous generator control for energy storage system

open access: yesInternational Journal of Electrical Power & Energy Systems
Aiming at the poor voltage response characteristics of the line-committed converter-based high voltage direct current (LCC-HVDC) transmission system after the fault of the AC system at the inverter side, this paper analyzes the relationship between the ...

4种多馈入高压直流输电子系统的仿真分析

open access: yesGaoya dianqi, 2018
以多馈入高压直流输电为例,分析了4种多馈入高压直流输电子系统的拓扑结构,基于PSCAD/EMTDC仿真软件建立了4种不同拓扑结构的多馈入高压直流输电子系统,通过接入受端弱交流系统,研究了4种多馈入子系统的暂态运行特性,仿真结果表明:整流侧为LCC、逆变侧为MMC的LCC-MMC HVDC系统的馈入有效地提高了LCC-HVDC的换相失败免疫力,缩短了故障恢复时间,改善了LCC-HVDC系统的暂态运行特性,提高了系统的供电可靠性。同时降低了VSC-HVDC、H-HVDC的工程造价和开关损耗 ...
