Electromagnetic transient/electromechanical transient hybrid real-time simulation is a focus in the area of power system simulation worldwide, and it is a very difficult issue. For this issue, and as the part one of the series papers named ＂The Research of Applied rTechnologies of Electromagnetic Transient/Electromechanical Transient Hybrid Real-Time Simulator and Their Implementa- tion＂, and aiming at the deficiency of SMRT （super mixed real-time simulation）, which is a system including parallel computers and RTDS, and adopting the current international advanced FPGA （field-programmable gate array） card for data exchanging, this paper de- velops a digital interface for electromagnetic tansient/electromechanical transient hybrid real-time simulation based on RTDS. Comparing to the results with RTDS electromagnetic transient simulation platform, the developed digital interface can decrease the simulation noise and increase the simulation precision effectively, and will promote the application of SMRT hybrid real-time simulation platform.
