Abstract

Overcurrent and abnormal voltages in the distribution system can cause not only burden of power plant but also damage to customers. As a result, researches related to the distribution automation have been widely conducted by utilizing a real time digital simulation to improve the reliability of power supply through rapid failure handing, reduction of power failure intervals and failure recovery. However, the distribution automation systems using the real time digital simulator are expensive and limited to verify actual hardwares. Therefore, in this paper, an external hardware devices was developed based on the distribution system analysis results of the digital simulator. And real-time simulation and functional verification are implemented by the real feeder remote terminal units used in distribution automation. The effectiveness of the proposed system is verified through several experiments.

배전계통에서의 과전류 및 이상 전압 현상은 전력설비에 부담을 줄 뿐만 아니라 수용가에 치명적인 피해를 입힐 수 있다. 그로 인해 실시간 배전계통 시뮬레이터를 활용하여 신속한 고장처리와 정전구간 축소 및 고장복구를 통한 전력공급의 신뢰도를 높이는 배전자동화 관련 연구가 활발히 진행되고 있다. 기존의 디지털 시뮬레이터를 이용한 배전계통 모의시스템은 고가의 설비로 시스템 구축에 제약이 있고 실 배전계통을 통한 검증 또한 불가능하다. 본 논문에서는 배전계통 디지털 시뮬레이터의 계통해석결과를 기반으로 배전자동화용 단말장치와의 연동을 통해 실시간 시뮬레이션 및 기능검증이 가능한 시스템을 개발하였다. 제안한 시스템의 효용성은 실험을 통해 검증하였다.
