An improved opportunistic group replacement maintenance strategy for wind turbines

open access: yesEnergy Science & Engineering, 2020
In traditional opportunistic group replacement maintenance (OGRM) strategy for wind turbines, the reliability thresholds of different subassemblies are set the same and its two‐step optimization for maintenance cost is diseconomy.
