Digital electric substation time synchronization system and method

摘要

According to an embodiment, a master synchronizer for outputting a reference pulse signal time-synchronized with a GPS signal; and performing time synchronization by receiving the reference pulse signal from the master synchronizer or a first synchronization completion signal from a merging unit, and adding a synchronization completion pulse to the reference pulse signal or the first synchronization completion signal A merging unit for outputting a second synchronization completion signal; includes, wherein the master synchronizer receives the nth synchronization completion signal (n is a natural number greater than or equal to 2) and analyzes the time synchronization delay time of each merging unit Digital substation time synchronization provide the system.
