【摘要】：对风电机组进行预防性检修,能够有效提高机组的可靠性。首先以风电机组单个部件的可靠度作为约束条件,以单部件单位时间检修成本最小作为目标函数,求得单部件的最佳检修周期和检修次数。在此基础上,对符合一定条件的部件进行机会检修,构建了风电机组的机会检修模型。最后,以机会检修策略下总的检修费用最小作为目标函数,以机组整体的可靠度作为约束条件,利用遗传算法对该模型进行求解以得到最佳的机会检修阈值和最小的检修总费用。通过算例分析表明,该机会检修模型能够有效节约总的检修成本。该研究对检修部门制定检修计划具有一定的参考意义。
[Abstract]:Preventive maintenance of wind turbine unit can effectively improve the reliability of the unit. Firstly, the reliability of single unit of wind turbine is taken as the constraint condition, and the minimum maintenance cost per unit time of single unit is taken as the objective function to obtain the best overhaul period and times of maintenance for a single unit. On this basis, the opportunity maintenance model of wind turbine is constructed. Finally, the minimum total maintenance cost under the opportunity maintenance strategy is taken as the objective function, and the overall reliability of the unit is taken as the constraint condition. The genetic algorithm is used to solve the model to obtain the optimal opportunity threshold and the minimum total overhaul cost. The analysis of an example shows that the opportunity maintenance model can save the total maintenance cost effectively. This research has certain reference significance to the maintenance department to draw up the maintenance plan.
