摘要
根据天广直流输电系统工程的实际参数,使用PSCAD/EMTDC电磁暂态仿真软件建立了包括交流系统、换流变圧器、整流/逆变器、交/直流滤波器、平波电抗器及直流输电线路的模型,并在PSCAD的CIGRE HVDC标准高压直流输电系统控制系统的基础上加以修改,搭建出天广双极双12脉动高压直流输电系统模型。仿真结果表明:该模型能够较准确地模拟天广直流输电系统,为研究双极高压直流输电线路故障提供了有效的工具。
Based on the parameters of Tianshengqiao--Guangdung HVDC transmission system, the model of AC system, converter transformer, rectifier, inverter, AC/DC fiher, smoothing reactor and DC transmission line are built up by PSCAD/EMTDC electromagnetic transient simulation software. After modifying the control system of HVDC transmission line model on CIGRE HVDC of PSCAD, /he bipolar and double 12-pulse HVDC lransmission system of Tian--Guang model is buih up. The simulation result shows that the model can simulate the Tian--Guang HVDC transmission system aceurately and provide an effective tool for fault researches of bipolar HVDC lransmission line.
