摘　　要：针对送端分址级联的特高压直流输电(UHVDC)系统特殊拓扑结构,设计了包含直流控制保护系统的硬件在环实时数字仿真系统与自主研发的可控控制保护平台。开发设计了基于数字化I/O接口装置和光电转换装置的二次接口方式,分别用于D/A、A/D数据交互和传输换流阀控制脉冲,极大优化了实时仿真平台与直流控制保护系统之间的通信接口设计。搭建了用于工程联调用的送端分址级联特高压直流输电实时数字仿真系统,系统测试证明该仿真系统设计方案适用于特高压直流联调试验研究。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 designed 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 sendingend multi-terminal substation cascade UHVDC transmission was established.System tests have proven that this simulation system design is suitable for UHVDC coordination tests.
