摘　　要：特高压直流输电系统含有大规模的电力电子器件,传统数字仿真无法真实模拟实际工程的多类型工况,必须使用物理实验的方式对相关拓扑、算法进行验证。此处提出了一种特高压直流输电数字物理混合实验平台的构建方案,在数字系统构建如风电场的交流系统仿真模型,在物理侧搭建特高压直流输电系统物理样机平台,并提出了新型功率接口算法以连接数字侧及物理侧。该平台可以有效模拟实际工程的动态特性,能够为相关设备及理论提供良好的工程适用性验证环境。The ultra-high voltage direct current transmission system contains largescale power electronic devices.The traditional digital simulation can not simulate the actual engineering of many types of conditions,so the physical experiment must be used to verify the relevant topology and algorithm.A scheme of ultrahigh voltage direct current transmission digital physical hybrid experimental platform is proposed.Alternating current system simulation model such as wind farm is built in digital system,and ultra-high voltage direct current transmission system physical prototype platform is built in physical side.A new power interface algorithm is proposed to connect digital side and physical side.The platform can effectively simulate the dynamic characteristics of actual engineering,and provide a good engineering applicability verification environment for related equipment and theory.
