| Abstract: | The traditional clock synchronization method has been unable to satisfy the demands of new generation power system on clock synchronization, while IEEE1588v2 time synchronization technique can achieve sub microsecond synchronization accuracy. Based on synchronization technique analysis of OTN and PTN, a 1588v2 clock signal transmission method in the hybrid network is proposed using application scenario of OTN＋PTN unifi ed synchronous network model, and the synchronization performance is tested and validated in the existing network. The result shows that the OTN＋PTN network model based on 1588V2 time synchronization technique can meet the high precision time synchronization requirements of digital substation and other electric power secondary equipment. |
