摘　　要：针对传统风电机组齿轮箱维修策略的不足,综合运用不完全维修和状态维修,提出一种考虑多属性的综合状态维修策略。在比例失效模型的基础上,考虑不同维修方式及其在维修决策中的配合应用。根据多属性决策理论,整合优化维修费用率、可靠度和可用度,建立联合目标函数。同时,构造两层优化算法,得到各目标函数的权重,并最终确定不完全状态维修和状态维修的动态维修阈值函数曲线。最后,结合某风电机组齿轮箱实际运行数据进行仿真分析,验证该维护策略的有效性和优越性。To avoid the problem caused by the traditional maintenance strategy for the gearbox of wind turbine, this paper integrate the conception of the multiple attribute value theory and the imperfect maintenance to the condition based maintenance strategy. On the basis of Proportional Hazards Model （PHM）, a comprehensive objective function, in which following items were taken as optimization objectives： the minimum maintenance cost rate, the maximum reliability and availability, was established based on the multiple attribute value theory. Meanwhile, a two hierarchy optimal iteration algorithm was used to make sure the weight of the comprehensive objective function and the dynamic maintenance threshold function curve of the two different maintenance strategies. Finally, taking a certain wind turbine gearbox as a case, the correctness and the superiority of the proposed approach was validated.
