摘　　要：为研究风电机组的维修方法,将风电机组简化为串联系统,分别以单周期串联系统的维修费用率最小、可用度最大、综合维修费用率和可用度指标为目标建立了计划型预防维修模型和机会型预防维修模型,引入权重系数,讨论了风电机组传动系统的最满意预防维修决策,并对2种预防维修模型进行比较。结果表明:当追求维修费用率小时,综合模型更接近维修费用率最小模型;当追求系统可用度大时,综合模型更接近可用度最大模型;与计划型预防维修方法相比,机会型预防维修决策可以进一步降低单周期内系统的维修费用率,提高系统可用度。To study the maintenance method for wind turbines, the planned and opportunistic preventive maintenance models were respectively established by simplifying the wind turbine as a series system, and taking the minimum maintenance cost, maximum availability and comprehensively considering both the minimum maintenance cost and maximum availability of the single-cycle system as the objectives. Subse- quently, the weight coefficients were introduced to compare the two preventive maintenance models to find the most satisfactory decision for the wind turbine transmission system. Results show that when the mini- mum maintenance cost is sought, the comprehensive model would be closer to the one based on minimum maintenance cost, and when the system availability is more concerned, the comprehensive model would be closer to the one based on maximum availability. Compared with the planned preventive maintenance meth- od, the opportunistic maintenance strategy can further reduce the maintenance cost and improve the availa bility of the single-cycle system.
