Problems solved by technology

If the previous physical interface technology is used, it is difficult to meet the requirements of such a large-scale test in terms of the number of interface channels and signal synchronization performance.
On the other hand, the interface speed requirements are getting faster and faster. For power electronic equipment with high frequency interruption such as STATCOM and light DC transmission, in order to ensure the simulation accuracy, it is necessary to use 20us or even smaller step size for real-time simulation and interface input and output. The step size of 50us~100us in the real-time simulation system cannot meet the requirements of the closed-loop test
