Breath stream real-time exchange with interact transmission, so as to realize two different principle systems it is real-time as an integrated system,
Synchronously mixed running.
At present, domestic and international researcher achieves certain achievement, big portion in terms of digital physical mixed Application Research on Simulation
Fractional module hybrid real-time simulation technology belongs to signal type, and mostly electrical secondary system is emulated in the numeral and physical mixed of ring, existed
Systematic analysiss are widely used with equipment real-time testing field, are mainly used in relay protection, comprehensive automation, excitation, power electronics
The test of the devices such as control system, but signal type Hybrid Real Time Simulation system voltage grade is low, application is limited to, no
Electric system simulation analysis demand can be met.
