- Abstract
- Recently, the PV(Photovoltaic) penetration has increased rapidly in Republic of Korea. And quite a lot of PV systems has been installed in small capacity. And the PV systems have difficult to have its own maintenance planning system due to difficulties in securing economic feasibility. Therefore the maintenance planning method for PV systems that can be generally applied are attracting considerable. Although the age replacement policy, one of the traditional RCM(Reliability Centered Maintenance) methodology, is excellent for determining the replacement cycle of facilities. But It evaluates that the facilities as good as new after maintenance. In this paper, the maintenance planning method for PV system facilities based on RCM has been proposed. To evaluate the failure rate after the imperfective maintenance, hybrid model has been applied. In addition, the economic feasibility of maintenance has been compared by considering investment cost and loss of the implementation for preventive maintenance policy.
