Analysis and implementation of IEEE 1588 time synchronizing design of bay level in digital substation

Along with rapid developing of digital substation and smart power grid, it is more and more important to have an in-depth study on time synchronizing design of bay level in digital substation. The time synchronizing design should be easy to maintain, should be easy to apply, and should also achieve high accuracies. Two kinds of network time synchronization method, SNTP and IEEE 1588 PTP, were introduced here. Analysis of comparison between this two methods is proposed. Based on this analysis, IEEE 1588 time synchronizing design which had higher precision was applied of bay level. Finally, a detail implementation progress using physical layer chip DP83640 was discussed in detail.
