| Abstract: | With the large-scale construction of the digitized substations,the requirements of the time synchronism precision in many intelligent devices are getting higher and higher.The working principle on IEEE1588 was introduced.In view of the digitized substation＇s actual demands,a feasible design and configuration synchronization network based on the IEEE1588 was proposed for substations.Then the redundancy configuration method of clock unit and its function implement were given.The detailed process of the determination of master clock and the concrete computational methods of system offset and delay were also discussed in this system design.The synchronization network scheme proposed herein provided the reference for internal high accuracy network clock synchronization in substation |
