In view of the special topology of UHVDC transmission system,a hardware in the loop real-time digital simulation system including DC control protection system and a controllable control protection platform by self-developing are designed.A secondary interface design based on digital I/O interface devices and optoelectronic conversion devices was developed and de-signed respectively for D/A and A/D data exchange,and transmission of converter valve control pulses,which greatly optimizes the communication interface design between the real-time simulation platform and the UHVDC control and protection system.Based on the RTDS real-time digital simulation platform,a simulation system for engineering coordination tests of the sending-end multi-terminal substation cascade UHVDC transmission was established.System tests have proven that this simulation sys-tem design is suitable for UHVDC coordination tests.
