| 摘 要： | 以云广±800kV特高压直流输电系统为研究对象，利用PSCAD／EMTDC仿真软件建立交流系统、换流器、换流变压器、交直流滤波器、直流平波电抗器、直流输电线路的仿真模型，研究直流控制分层控制原理及其在PSCAD／EMTDC中的等效实现方法，利用该仿真平台进行云广±800kV特高压直流输电系统的控制系统建模。将基于本平台搭建的电磁暂态模型与实际工程系统调试时的波形进行了对比，证明该平台与工程实际控制保护系统功能等效。基于该平台进行直流工程控制系统仿真的结果可信，有利于更深入的研究高压直流输电的控制与保护系统并对分析结果进行仿真验证，具有工程实际指导意义。

| Abstract: | This paper investigates the control strategies of YunGuang ~ 800 kV ultra-high voltage direct current power transmission system,where simulation models of ahemative current system, converters, converter transformers, AC / DC filters,smoothing reactors and DC power transmission lines are carefully studied, and a PSCAD/EMTDC YunGuang ＋ 800 kV UHVDC system and its related control system are constructed to simulate the hierarchical control strategies. Data collected from field operation and commissioning is used to verify the simulation model. Test results show that the con- structed YunGuang ＋ 800 kV UHVDC system is sufficient to perform protection impact studies. |
