Research on Time Delay System Based on Time-free Crossover

The network-based IEEE 1588 precision clock synchronization protocol is an accurate time synchronization method that meets the requirements of key applications in smart substation in the future. In this paper, a dynamic delay curve, comprehensive curve fitting and bad data analysis are used to rationally plan the active curve delay between two substations, and finally determine the situation. The same profile improves the usability of the IEEE 1588 time synchronization system.
