摘　　要：高压直流输电及特高压直流输电的大力发展,交直流相互作用问题日益突出。该文基于电磁暂态仿真软件PSCAD/EM TDC,给出了直流输电系统电磁暂态模型的一般建模方法、控制系统参数选择分析方法、控制系统静态特性校验方法及系统动态性能分析方法,以此验证交直流一次系统建模及控制与保护系统建模的有效性,为准确分析交直流相互作用提供有力基础。As the development of EHVDC and UHVDC in China, AC/DC interaction becomes more and more prominent. Setting up adaptive and valid AC/DC system models including the AC/DC primary system, the DC control and protection system is of vital importance. This paper proposes the methods of the primary system modeling, the control system parameters selection and optimization, the HVDC steady UI characteristic verification and HVDC system dynamic performance analysis based on the electromagnetic transient software PSCAD/EMTDC. These methods can make the trusted analysis for point to point AC/DC interaction as well as the multi-infeed AC/DC interaction.
