摘　　要：±800 k V特高压直流输电技术是实现全球能源联网及大范围资源优化配置的核心技术之一,针对特高压直流输电的电磁暂态仿真研究是保证工程成功的必要环节。基于ADPSS仿真装置中电磁暂态仿真程序ETSDAC建立换流器、换流变压器、交直流滤波器、直流输电线路等仿真模型,并在此仿真平台上对某实际系统在两种故障情况下进行单极全压仿真模拟,与PSCAD电磁暂态仿真计算模型进行比较分析。结果显示:两个程序的计算结果基本一致,所建模型可较准确地模拟特高压直流输电系统动态特性。ETSDAC可以作为研究特高压直流输电系统的有效工具。±800 k V ultra-high voltage direct current（UHVDC） power transmission technology is one of the core technologies in implementing the construction of global energy internet and optimizing the allocation of energy resources of our nation. The electromagnetic transient simulation analysis is the essential step in the successful construction of a UHVDC system. The simulation models of converter, converter transformer, AC/DC filter and DC power transmission line are established based on electromagnetic transient simulator for DC and AC power system（ETSDAC） in ADPSS simulation device（Advanced Digital Power System Simulation）. Depending on ETSDAC, this paper proceeds analysis on single-stage full voltage simulation of a real system under two fault conditions, which is compared with PSCAD electromagnetic transient simulation calculation model. The results show that the calculation results of the two programs are basically the same, and the established model could accurately simulate the dynamic characteristics of the UHVDC power transmission system. ETSDAC can be an effective tool for studying the UHVDC system.
