Compound Line-Commutated Converter with Commutation Voltage Compensation and Power Consumption Capability for Commutation Failure Suppression

CSEE Journal of Power and Energy Systems
To mitigate commutation failures (CFs) of a line-commutated converter based-high voltage direct current transmission system (LCC-HVDC), an evolved thyristor based full bridge sub-module (ET-FBSM) and a compound LCC (CLCC) topology are proposed with the ...

4种多馈入高压直流输电子系统的仿真分析

Gaoya 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 ...
