| Abstract |
Power equipment has a characteristic that its failure probability increases exponentially with its service life, so initial failures of power equipment are rare. However, existing maintenance methods result in cost inefficiencies because maintenance is applied to healthy equipment that does not require maintenance. To address this issue, research is being conducted on risk-based maintenance strategies that prioritize equipment based on risk, considering the failure probability and ripple effects of failures, to manage equipment cost-effectively and ensure stable system operation. Since the failure probability of equipment varies depending on the maintenance applied, this should be considered when developing a maintenance strategy. Therefore, this paper applies a Risk-Based Maintenance (RBM) approach to develop a cost-effective maintenance strategy and verifies the performance of the RBM-based maintenance strategy. |
