This paper introduces the use of an RTDS for the verification of HVDC control and protection.For high accuracy firing and high frequency simulation requirements,a new approach for an Advanced Hybrid HVDC Real- Time Sim ulator using classical physical m odels for the converter section in combination with a complex fully digital AC and DC power system simulator im plem ented on RTDS is developed.The realization and performance verification of its technology are described. This hybrid sim ulator has been chosen for Chinese Tian- Guang HVDC project tests.Based on the testing of HVDC control and protection,new m odels for this hybrid simulator set- up are implemented and verified by tests.Compared with EMTDC com puter simulations,the control and protection performance is verified and the results are also given.
