摘要
以云广±800kV特高压直流输电系统为研究对象,根据云广特高压直流输电工程的实际工程参数,采用PSCAD/EMTDC仿真软件,建立了交流系统、换流变压器、交直流滤波器、换流阀、平波电抗器、输电线路的准确模型.参照CIGRE HVDC标准测试系统的控制系统并进行修改,建立云广特高压直流输电系统控制系统的仿真模型.根据云广特高压直流输电系统一次系统模型和控制保护系统模型,搭建出云广±800kV特高压直流输电系统单极双12脉动接线方式下的精确仿真模型并进行仿真.仿真结果表明本模型可较准确地模拟云广特高压直流输电系统,可以作为研究云广特高压直流输电系统的有效工具.
In this paper,the Yunnan-Guangdong UHVDC transmission system is the research object,and the simulation tool is PSCAD/EMTDC.According to the parameters of Yunnan-Guangdong UHVDC transmission system,the accurate models of AC system,converter transformer,AC/DC filter,converter,smoothing reactor and transmission line are built up.Referring to the standard testing system CIGRE HVDC,the simulation model of the control system is established,too.Based on the primary system model and the control system model,the accurate model of Yunnan-Guangdong UHVDC transmission system is built up and simulated.The simulation result shows that the model can simulate the Yunnan-Guangdong UHVDC transmission system accurately,so it can be used as the research tool for Yunnan-Guangdong UHVDC transmission system.
