초록
최근 전국 각 지역 AMI(Advanced Metering Infrastructure) 원격검침 시스템의 보급사업이 활성화되고 있으며, 전력수요 관리를 위한 양방향 통신 및 보안 요금제 기능 등 다양한 계량 기능을 제공하고 있다. 현재 AMI 시스템은 새로운 내부 IoT 장비 및 네트워크 규모의 증가로 인해 기존 RDB(Relational Database) 기반 장애 분석이 어렵다. 본 연구는 기존 RDB 데이터를 활용하는 새로운 GDB(Graph Database)기반 장애 분석 방법을 제안한다. 내부 임계치와 상태 값 등 누적된 데이터를 통해 새로운 장애 패턴의 상관관계를 분석한다. GDB 기반 시뮬레이션 결과 RDB에서 분석이 어려웠던 새로운 장애 패턴을 예측할 수 있음을 확인하였다.
Abstract
Recently, the spreading business of AMI (Advanced Metering Infrastructure) remote metering systems in various regions of the country has been activated, and it provides various metering functions such as two-way communication and security plan functions for power demand management. Current AMI system is difficult to analyze based on the existing RDB(Relational Database) due to the increase in the size of new internal IoT devices and networks. This study proposes a new GDB(Graph Database) based failure analysis method that utilizes existing RDB data. It analyzes the correlation of new failure patterns through accumulated data such as internal thresholds and status values. As a result of GDB-based simulation, it was confirmed that RDB can predict to a new obstacle pattern that was difficult to analyze.
