摘要

为解决风力机多部件难以制定合理的维修策略和运维成本较高的问题,考虑各部件经济相关性,提出一种基于费效比的风力机边界强度机会维修优化模型。首先,基于边界强度过程建立混合故障强度模型来描述故障变化规律;其次,将机会维修思想和成本效益分析纳入多部件预防性维修中,通过费效比选择维修方式;最后,借助风力机中的发电机、齿轮、叶片、轴承4个部件进行算例分析,并与未考虑机会维修模型和威布尔分布模型进行对比。结果表明：所提模型比未考虑机会维修模型总成本节约2.76%,比威布尔模型总成本节约0.88%。

Abstract

In order to solve the problem that it is difficult to formulate reasonable maintenance strategies for wind turbine multi-components and the problem of high operation and maintenance costs, this paper considers the economic relevance of each component and proposes a wind turbine boundary intensity opportunistic maintenance optimization model based on cost-effectiveness ratio. Firstly, based on the boundary intensity process, a hybrid failure intensity model is established to describe the change rule of failure; secondly, the idea of opportunistic maintenance and cost-benefit analysis are incorporated into multi-component preventive maintenance, and the maintenance methods are selected through the cost-effectiveness ratio; lastly, a numerical case study is analyzed with the help of four components of wind turbine, namely, generator, gears, blades, and bearings, and a comparison is made with the model of unconsidered opportunistic maintenance and the Weibull distribution model. The results show that the model in this paper reduces the total cost by 2.76% compared with the model without considering opportunistic maintenance, and sky 0.88% compared with the Weibull model.
