摘　　要：电力系统实时数字仿真器RTDS已经在电力系统仿真分析、控制保护设备的闭环测试、交直流系统的相互影响分析以及直流系统的控制研究等方面得到了广泛应用。介绍了根据向家坝—上海±800 kV特高压直流输电示范工程,在RTDS上进行的特高压直流输电系统的一次系统建模,并搭建了具有一定通用性的RTDS内部控制系统。经闭环测试,该模型在稳态和暂态情况下均有较好的运行特性,为进一步研究特高压直流输电系统的输电性能以及RTDS装置的仿真精度提供了相关的试验依据。Real-time digital simulator RTDS has been widely used in power system simulation,closed-loop testing of control and protection devices,analysis of interaction between AC and DC systems,and the control of DC system.This paper presents a case study of ＂Xiangjiaba—Shanghai ± 800 kV UHVDC transmission demonstration project＂.A modeling of the UHVDC transmission system was carried out,and an internal control system with a certain universality on RTDS was established.Through closed-loop testing,it is proved that the model works well in both steady and transient cases.It provides an experimental basis for further study of HVDC transmission system performance and accuracy of RTDS simulation device.
