摘要/Abstract

摘要： 海上风电机组的维修费用较高，在一定程度上限制了海上风电产业的发展。针对此现象，提出一种将故障维修与预防性维修相结合的机会维修策略。考虑海上天气情况对维修活动的影响，采用马尔科夫法和动态时间窗描述海上天气状况，提出可及度指标评估海上风电机组维修的可及性。运用蒙特卡洛法模拟部件的随机故障，并选择合适的周期，以周期内成本期望值最小为目标，对仅考虑更换措施以及考虑不完全维修、更换措施的机会维修策略的维修阈值进行优化。以某海上风电机组为例进行仿真，结果表明，考虑不完全维修、更换措施的机会维修策略对降低海上风电维修成本的效果更为可观，从而证明该策略的有效性。

Abstract: Maintenance of offshore wind power plants is known to be expensive and costly and limits the development of offshore wind power industry to a certain extent. In order to solve this problem, the paper proposes an opportunistic maintenance method, which can function both correction and prevention. Considering the impact of weather conditions on the maintenance activities, this method applies the Markov method and dynamic time window to represent the weather conditions, and the index used to evaluate the maintenance accessibility is then proposed. During the investigation, the Monte Carlo method is applied to simulate the component failures and select the appropriate cycle. Taking the minimum expectation cost as objective function, the opportunistic maintenance is optimized by considering the strategy of the perfect maintenance and the strategy of both perfect and imperfect maintenance. An offshore wind farm is taken for simulation case study, and the simulation results indicate that the opportunistic maintenance considering both perfect and imperfect strategies is more economical, which proves the effectiveness of the method.

Key words: wind power, offshore wind turbines, opportunistic maintenance, Markov, dynamic time window, maintenance accessibility (OWMA) index
