Quantity Optimization of Spare Parts For Offshore Wind Farm Based on Component Updating

The important parts of the offshore wind turbines are expensive. The irrational allocation of spare parts will lead to low availability of wind turbines and an increase in cost. In order to reasonably determine the number of spare parts, an optimization scheme for the number of spare parts of offshore wind farms based on component updating is proposed. First, considering the complex deterioration process of the components, the time delay theory is introduced in this paper, and time delay theory is applied to the maintenance strategy of offshore wind turbine. This article optimizes the component update cycle through the component maintenance strategy. Then, considering the cycle of spare parts, the availability of the entire wind farm components is taken as the goal with maintenance strategy. The number of spare parts of the offshore wind farm is optimized through the Markov process. Finally, taking the components of the wind turbine as an example, the traditional optimization process is compared. The example shows that the method can correctly configure the number of spare parts and effectively reduce the cost of spare parts management.
