摘　　要：采用PSCAD/EMTDC仿真软件建立了交流滤波器、换流变压器、直流滤波器、直流平波电抗器、直流输电线路的初步模型,参照CIGRE HVDC标准模型的控制系统并进行修改,初步建成模型中的直流控制系统;以福建规划中的特高压直流输电系统为研究对象,利用特高压直流输电工程的典型模拟参数,搭建了直流输电系统,并与运用ATP/EMTP建立的直流输电模型的仿真结果进行对比分析,验证了所建模型能较精确地模拟特高压直流系统,可作为建设和研究特高压直流输电系统的模型和工具。This paper discusses preliminary model of AC filter,converter transformer,DC filter,filter DC reactor and DC power transmission line by using PSCAD /EMTDC. The simulation model of control system is built based on the standard testing system of CIGRE HVDC,taking the plan of Fujian UHVDC transmission system as study object,according to the classic simulate parameter of UHVDC transmission system to model the UHVDC system and compare with ATP /EMTP,the result shows that the established model is able to correctly simulate UHVDC transmission system which can be conducted as the model and tool for studying and building UHVDC transmission system.
