In order to meet the development need of modern power systems, this paper proposes a architecture of the universal high power digital-analog hybrid simulation system. And it adopts the improved interface algorithm based on ideal transformer model （ITM）, the high power interface on the physical side based on power electronic converter and the anti-interference signal interface system, and achieves the 400 V/ 50 kVA high power digital-analog hybrid real-time simulation system. Digital analog hybrid simulation experiments have been carried out on the digital-analog hybrid simulation platform, by comparing the results of real-time digital simulation, which verifies the stability and accuracy of the system.
