Zusammenfassung:	The present invention relates to an AMI system and method of accomplishing the detection and synchronization of phase in an AMI communication network of a relay communication manner. The AMI system for accomplishing the detection and synchronization of phase in an AMI communication network of a relay communication manner according to an embodiment of the present invention includes: an AMI server for collecting ″reference ZCD time difference for each phase″ with respect to the lead-out terminal of a main transformer installed in a substation; and a data concentration unit (DCU) for comparing ″ZCD time difference for each phase″ collected at the same time with the ″reference ZCD time difference for each phase″ transmitted from the AMI server so as to have a time difference close to an error range. It is possible to collect and synchronize electrical phase information from the substation to a final customer. 본 발명은 중계통신방식의 AMI 통신망에서 위상 검출 및 동기화를 수행하는 AMI 시스템 및 그 방법에 관한 것으로, 본 발명의 일실시예에 따른 중계통신방식의 AMI 통신망에서 위상 검출 및 동기화를 수행하는 AMI 시스템은, 변전소에 설치된 주변압기의 인출단에 대해 '위상별 기준 ZCD 시간차'를 수집하기 위한 AMI 서버; 및 상기 AMI 서버로부터 전송된 '위상별 기준 ZCD 시간차'와 동일 시간에 자신이 수집한 '위상별 ZCD 시간차'를 비교하여 오차범위 내에 근접하는 시간차를 가지도록 일치시키기 위한 DCU(Data Concentration Unit);를 포함한다.
