摘　　要：随着电力系统发展,纯机电暂态和电磁暂态仿真在分析大规模特高压交直流混合电网时已呈现明显不足。为了准确分析特高压交直流输电系统的动态特性,文中基于电力系统全数字实时仿真平台(ADPSS)搭建了特高压交直流输电系统的机电—电磁暂态混合仿真模型,并对整流侧和逆变侧交流母线故障进行了仿真分析。结果表明通过机电—电磁暂态混合模型仿真结果输出,能够有效体现直流系统整体以及局部的各个元器件的详细动态过程,为特高压交直流系统的稳定控制提供技术理论支撑。With the development of power systems, the electromechanical transient simulation and electromagnetic transient simulation have become insufficient for large-scale UHV AC/DC hybrid power grids. In order to accurately analyze the dynamic characteristics of UHV AC/DC transmission systems, this paper builds an electromechanical and electromagnetic transient hybrid simulation model for an UHV AC/DC transmission system based on the advanced digital power system simulator （ADPSS）, and simulates the AC-bus faults on rectifier side and inverter side. The results show that the output of the electromechanical and electromagnetic transient hybrid model can effectively reflect the detailed dynamic process of whole or partial DC system. This study may provide theoretical and technical support for the stability control of the UHV AC/DC system.
