초록

본 논문에서는 스마트 그리드 배전 시스템이 요구하는 디지털 FRTU(: Feeder Remote Terminal Unit)를 위한 통신 방법론을 연구하였다. 디지털 FRTU는 고장처리부와 통신부로 구성하는데, 고장처리부는 고장 시 고장정보를 통신부로 전송하며, 통신부는 주변 디지털 FRTU간 양방향 통신을 통해서 고장구간을 자율적으로 판별할 수 있도록 설계하였다. 성능 검증을 위해서 다양한 고장 시나리오들에 대한 고장모의가 가능하도록 3개의 디지털 FRTU를 기반으로 3개의 선로구간을 구성하는 하나의 성능 검증 시스템을 구축하였다. 구축된 성능 검증 시스템 상에서 1선 지락고장, 선간 및 3상 단락고장을 포함하는 다양한 고장 경우들을 실험적으로 모의하였으며, 각 경우에서 정확한 추론결과를 검증으로써 개발된 방법론의 유효성을 확인할 수 있었다.

In this paper, a communication methodology for the digital FRTU(: Feeder Remote Terminal Unit) required by the smart grid distribution system was studied. The digital FRTU consists of a fault handling unit and a communication unit. The fault handling unit transmits fault information to the communication unit in case of a failure, and the communication unit is designed to autonomously determine the fault section through two-way communication between surrounding digital FRTUs. For performance verification, a performance verification system consisting of 3 line sections based on 3 digital FRTUs was constructed to enable fault simulation for various failure scenarios. Various fault cases including one phase ground fault, line-to-line short-circuit fault, and three-phase short-circuit fault were experimentally simulated on the established performance verification system, and the validity of the developed methodology was confirmed by proving the accurate fault section inference results for each fault simulation case.
