The present invention relates to a system for performing phase detection and synchronization in an AMI communication network using a relay communication, and a method thereof. According to an embodiment of the present invention, a system for performing phase detection and synchronization in an AMI communication network using a relay communication includes an AMI server for collecting a 'reference zero-crossing detection (ZCD) time difference by phase' of input/output terminals of a main transformer installed in a substation; and a data concentration unit (DCU) comparing the 'reference ZCD time difference by phase' transmitted from the AMI server with a 'ZCD time difference by phase' collected by itself, and matching the same to have a time difference close to an error range.
