Gaoya dianqi, 2012 为抑制直流输电系统扰动引起的直流电流上升速度,避免轻载时发生直流电流断续,以及降低直流侧谐波,需要在换流器直流侧出口装设平波电抗器。笔者根据±800 kV云广直流输电系统主回路结构,详细计算了平波电抗器的电感参数;特高压直流输电系统由于采用特殊的换流器联络结构,其平波电抗器布置不同于±500 kV超高压直流输电系统。文中搭建了基于PSCAD/EMTDC的云广特高压直流输电模型,从谐波特性、直流操作过电压等方面对3种平波电抗器布置方案进行了仿真对比研究,其结果对实际工程具有一定的指导意义。

Gaoya dianqi, 2023 为了防止柔性直流输电系统在双极短路故障下过大的短路电流损坏输电系统，且考虑到过大的短路电流也会损坏断路器的避雷器，文中提出了一种可开断故障电流且有效减小避雷器吸能的直流断路器。利用PSCAD搭建了含卸能电阻的直流断路器模型和三端±350 k V柔性直流输电系统模型。在双极短路故障下，通过仿真对比分析了此模型与理想直流断路器模型和不含卸能电阻的直流断路器模型的区别。文中发现，含卸能电阻的直流断路器与理想直流断路器相比更容易切断故障电流，与不含卸能电阻的直流断路器相比有效减小了避雷器吸能。并且 ...
