AMI system for performing phase detection and synchronization in AMI communication network using relay communication method, and method thereof

Abstract:

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.
