태양광 시스템의 신뢰성 중심 적응형 유지보수 계획

Abstract

Recently, as the supply of photovoltaic systems has increased, photovoltaic facilities with long operation days are increasing. As the number of operating days of a photovoltaic facility increases, the failure rate increases. Failures of these facilities affect the reliability of the connected power system. In addition, photovoltaic generation operators suffer cost losses when supply is disrupted. Therefore, a proper maintenance plan for photovoltaic facilities is required. This paper established an adaptive maintenance plan for photovoltaic systems focusing on reliability. Reliability was analyzed through the life evaluation of each piece of equipment in the photovoltaic system, and the system reliability index was calculated.
