摘　　要：与陆上机组相比,海上风电机组运行维护成本较高,在分析海上风电机组运行维护主要影响因素的基础上,用模糊时间函数表示维护各任务执行时间的不确定性,依据维护任务的模糊Petri网建模规则,把模糊关键路径的求取转换为一个代数方程问题,并通过算例分析了某机组维护任务在约定工期下完成的概率。结果表明:所提出的模型可正确、直观地表达运行维护任务,并能进行有效的分析。In contrast to wind turbine on land,the cost of operation and maintenance （O＆M） for offshore wind turbine is higher.On the basis of the analysis of main factors for offshore wind turbine＇s O＆M,a novel operation and maintenance model based on Petri nets is proposed.The uncertainty is represented as fuzzy-timing function and the problem of critical path is converted into algebric equations according to fuzzy Petri nets modeling rules.Then the possibility of project completion is also discussed with time restriction.The results indicate that the model can generate the O＆M project properly with correct intuition and can provide effective analysis.
