Abstract

The diesel driven power generation facility provides most of electricity of island region where is isolated from the main land power supply system. It is possible to extend the life of diesel driven power generation facility by periodic maintenance. However, the long-term use of diesel driven power generation facility increases the operating cost due to aging hardware and reduced plant efficiency. In other words, on-time replacement of aging diesel driven power generation facility reduces plant operation cost. The purpose of this study presents major indicators to represent the characteristics of the diesel generator and conducts sensitivity analysis using Monte Carlo analysis. In addition, status core which indicates quantitatively the state of the diesel driven power generation facility is defined and prepare the replacement criteria based on the state score.

내륙의 주전력 공급계통과 단절되어 있는 도서지역은 대부분의 전력공급을 디젤발전설비가 담당하고 있다. 디젤발전설비는 특성상 예방정비 및 유지보수를 통해 사용수명을 연장시킬 수 있으나, 계속 사용에 따른 기계설비의 노후화 및 발전 효율 감소로 인해 운영비가 증가한다. 즉, 적기에 노후 발전설비를 교체할 경우 발전소 운영비용을 줄일 수 있다. 이에 본 연구에서는 디젤발전설비의 상태를 대표할 수 있는 지표를 도출하고, 몬테카를로 시뮬레이션을 이용하여 각 지표별 민감도 분석을 수행하고자 한다. 이를 통해 디젤발전설비의 현상태를 정량적으로 나타낼 수 있는 상태점수를 정의하고 이를 바탕으로 설비 교체의 기준을 마련하고자 한다.
