摘要：

The conventional SV (Sampling Value) network technology is analyzed and a kind of distributed synchronization technology of SV network is proposed for the process layer of smart substation. Its concept is that: each SV sending device has an IEEE1588 master clock, which, without external synchronization, operates based on the local crystal frequency and is tracked by the slave clock of each SV receiving device; the SV receiving device receives the SV data from the SV sending device and synchronizes them by the backtracking interpolation. Compared to the conventional SV network method, the proposed technology does not need the global external synchronization system and has higher reliability. The results of field test show that, the sampling synchronization and performance stability are ensured.
