摘要
\tThe IEEE1588 network time synchronization, matched withsmart substation information network transmission, is becomingthe next generation advanced data synchronization of the smart substation. Itis known that the inherent asymmetry error of the network synchronizationapproach in the smart substation is highlighted, which is concerned particularly.This paper models the synchronization process of the IEEE1588 based on thecommunication simulation software of OPNET Modeler. Firstly, it builds themodels of master-slave clock, IEEE1588 protocol and network synchroniza- tionmodel, and analyzes the composition and influencing factors of the asymmetryerror. Secondly, it quantitatively analyzes the influence of the synchronousasymmetric error of the IEEE1588 affected by the network status differences andthe clock synchronization signal transmission path differences. Then itscorrection method is analyzed, in order to improve the IEEE1588 synchronizationreliability and gives the solutions to its application in smart substation.
