In order to realize effects of complement each other’s advantages and optimization on simulation of combination of real-time simulation and physical simulation of power system,a method of ideal transformer model decoupling was used to realize power connection technology for all-digital real-time simulation device and physical simulation device and develop power exchange typed digital-analog connector. Meanwhile,a digital-analog hybrid simulation model of large power grid system was built for experiment by using this power connection technology. Comparison analysis on results of digital-physical hybrid simulation test and all-digital simulation test indicated that this technology was of higher simulation precision,stability and good practical value.
