Because through expansion of the optical port of the interface card, transmission of all interactive data between the two real-time simulation systems can be completed within a simulation step size without increasing the number of interface cards, the step of real-time simulation conversion is omitted, the problem of poor consistency and compatibility of various interface cards is solved, and the real-time performance of a whole simulation system is improved. The data transmission method of the electric system hybrid real-time simulation platform is accurate, effective, convenient to implement and flexible.
