Description

technical field [0001] The present invention relates to the technical field of simulation systems, in particular to a simulation system clock synchronization method, device, equipment and storage medium. Background technique [0002] Most of the current real-time simulation systems and control and protection systems are connected through analog quantities. But in recent years, digitization is a trend, and digitization makes wiring simple and convenient, so more and more simulation systems and control and protection systems are connected by digital quantities. If the digital interface is used, since both the real-time simulation system and the control system are discretely operated, and the two systems use different clock sources, it is easy to have clock synchronization problems, resulting in system instability. Contents of the invention [0003] The embodiment of the present invention provides a simulation system clock synchronization method, device, equipment and storag...
