The process level monitoring terminal unit is one of excellences in the discrimination of digital substation and tradition substation, but implementation technology is more complex. This paper expounds the concept of digital substation of process level, with the analysis and contrast of the existing synchronization technologies, a new digital substation synchronization method by the use of GPS synchronization and NTP network synchronization is proposed. The GPS synchronization design uses FPGA technology, which can satisfy the needs of synchronized accuracy in the power system. The proposed method has important theory significance and engineering value to the conventional digitization transformation.
