基于RTDS的数字化仿真接口装置研制与应用OA

To meet the urgent demand for simulation test platforms with high efficiency and cost performance in high-voltage direct current(HVDC)transmission engineering,this paper develops a digital simulation interface device compatible with the Real-Time Digital Simulator(RTDS).The device aims to replace various specialized boards in the RTDS system(such as GTAO,GTDO,GTDI,GTFPGA,etc.),as well as conventional AC/DC measurement devices and switch interface units.Through integrated design,it effectively reduces the complex physical wiring and hardware configurations inherent in traditional simulation systems.Practical applications demonstrate that the device significantly simplifies the closed-loop simulation testing architecture for HVDC transmission control and protection systems.While ensuring simulation accuracy and real-time performance,it substantially reduces system construction costs and complexity.This provides a more practical,reliable,and economical simulation solution for the system design,equipment testing,and operational strategy validation of HVDC transmission projects.
