摘　　要：介绍了特高压交直流输电系统换流站的多种接线方式,分析了换流站运行可靠性、分期建设及换流变压器的制造、运输等因素对交流侧的影响。并结合福建省特殊的地理气候环境,通过采用PSCAD电磁仿真软件进行分析验证。结果表明:双12脉动串联接线在目前情况下是一种较为适合的接线方式,其为规划中的由浙西接入福建电网的±800 k V、6 400 MW特高压直流输电系统的接线方式提供了参考。Introduction was made to the multiple-line connection method of ultra-high voltage（UHV） alternating current（AC）/ direct current（DC） transmission convertor station. Analysis was made to the operation reliability of convertor station, impacts of construction in stages, manufacturing of converting transformer; transport etc factors at AC side. This paper combined with Fujian province special geographic climate environment to carry out analysis verifi cation via adoption of PSCAD electromagnetic simulation software. The result shows that double 12 pulse series connection is a more suitable way of line connection method, it has provided a reference for line connection way from the west Zhejiang to Fujian grid of positive and negative 800 kV, 6 400 MW UHVDC transmission system.
