The high precision time synchronization principle based on IEEE 1588 is introduced.The hardware scheme and software process of synchronization in the merging unit based on IEC 61850-9-2 is discussed in detail.Then,the network scheme for synchronization of process layer devices is analyzed.Finally,the implementation of the GARP multicast registration protocol(GMRP) is analyzed prior to the use of the device in a digital substation.
