A Route of the Time Stamp Data Detection of Power System Based on Intelligent Substation Communication Physical Layer
The big difference between off line/online analysis on The deviation of phase angle measurement in the power grid is likely to occur, as well as the presence of the unbalance of load flow calculation in the substation domain and the large deviation of the fault analysis.This article researches the time synchronization of the power system and its time stamp data by discusing its sources, role and the application.Based on the time system principles of the theory of digital signal processing, this article analyzes the IED digital signal of the time response data and the physical layer signal of the time stamp data, and compares with the physical consistency of information and time stamp data detection signal.Finally, the paper gives the technical approach to detect the time stamp data of power system on physical layer.
