The rated voltage of Yindong HVDC system is ±660 kV. It is the first ±660 kV HVDC project in the world. A modeling method for analyzing the dynamic characteristics of the Yindong HVDC system is presented based on PSCAD electromagnetic transient simulation software. This method directly uses the designed data of the HVDC project
and the models of the control system and the main circuit are established in detail. Its accuracy is verified with the actual fault data through the recorded fault waveform and data on site. It is showed that this method has a certain reference to the stable operation and the fault analysis of the HVDC transmission system.
