摘要(Abstract)：

柔性直流输电系统接入电力系统主网络,使得电网交直流耦合更加紧密,同时精确地仿真柔性直流输电系统和大规模交流电网成为一个全新的挑战。文章从系统仿真研究的角度,提出一种基于HYPERSIM的柔性直流输电系统数模混合仿真建模方法,该方法以超级并行计算机SGI为核心,接入了实际柔性直流输电工程的控制保护装置。文中从仿真模型构架、一次系统建模、控制保护系统的简化原则、实现以及数模接口技术等方面对所提模型展开深入研究。选择渝鄂±420kV背靠背柔性直流输电工程施州换流站的典型试验,将所提模型的仿真结果与现场试验波形进行了详细的对比,结果表明所提模型的动态响应特性与实际工程的响应特性吻合,可以为研究柔性直流与大规模交直流混联电网间的相互影响提供准确的仿真工具。
