A Predictive Maintenance Policy Based on the Blade of Offshore Wind Turbine
Résumé
Based on the modeling of the deterioration of a blade due to the intrinsic randomness, random shock, random load and dynamic environment, this paper proposes a predictive maintenance policy considering the leading time caused by preparing the maintenance action. The evaluation of the proposed maintenance policy is realized by Monte-Carlo simulation and the minimal average long-run maintenance cost per unit time is obtained. The numerical simulations prove that the proposed policy can reduce the downtime caused by failure or leading time.
