Abstract

In this paper, a miniaturized distribution line was experimentally made. The smart grid distribution system was modeled by analyzing the distribution system, and a miniaturized micro three phase distribution system recloser was designed. The micro recloser was designed as a sensor part, a main part and a relay part, and the main part was designed to cut off the fault current by determining the fault from the input current based on the DSP. Finally, based on the results of the modeling, the micro three phase power distribution line and the micro three phase recloser were experimentally fabricated, and the basic making technology of the miniaturized micro smart grid was obtained through the making process.

본 논문에서는 소형화된 배전선로의 실험적 제작에 대한 연구를 수행하였다. 배전계통을 분석하여 스마트 그리드 배전계통을 모델링하였으며, 소형화된 마이크로 3상 배전계통 리클로저를 설계하였다. 마이크로 리클로저는 센서부, 주제어부 그리고 릴레이부로 설계하였으며, 주제어부는 DSP를 기반으로 입력전류로부터 고장여부를 판별하여 고장전류를 차단하도록 설계하였다. 끝으로 설계 결과를 기반으로 마이크로 3상 배전계통과 마이크로 3상 리클로저를 실험적으로 제작함으로서 기초 제작 기술을 확보하였다.
