The technical characteristics of control and protection platform based on Xuji′s new generation HCM5000 and the basic structure of hybrid cascaded UHVDC transmission system are introduced. Taking hybrid cascaded UHVDC transmission system as the object, the control and protection RTDS simulation platform based on HCM5000 device is built, and the improvement measures from two aspects of I/O interface and inner loop logic implementation for simulation platform of hybrid cascaded UHVDC transmission system based on HCM5000 are described, and the system architecture and configuration scheme of simulation platform are explained. Finally, it is verified that the simulation results have met the requirements of national standards by comparing the test results with the relevant standards, which shows that the simulation platform of hybrid cascaded UHVDC transmission control and protection system based on HCM5000 can provide a reference basis for the study of operation characteristics and control and protection strategies of hybrid cascaded UHVDC transmission system.
