摘要
针对复杂天气变化影响下海上风电机组维护决策问题,提出了考虑高风速与低风速影响的海上风电机组两阶段滚动优化机会维护策略.首先,提出考虑高风速冲击影响的维护役龄回退模型,量化实际部件退化与及维护成本关系.其次,建立了考虑低风速停机事件维护机会影响的海上风电机组长短期两阶段预防性机会维护模型,滚动更新长期预防性机会维护阈值.最后仿真结果表明,本文所提模型能够有效降低海上风电机组停机成本以及故障损失,提高机组寿命周期内的维护效益.
Abstract
Aiming at the maintenance decision-making problem of offshore wind turbines under the influence of complex weather changes,a two-stage rolling optimization opportunistic maintenance strategy for offshore wind turbines considering the influence of high wind speed and low wind speed is proposed.Firstly,a maintenance age regression model considering the impact of high wind speed impact is proposed,and the maintenance cost-benefit relationship is quantified based on the actual reliability of components.Secondly,a long-term and short-term two-stage preventive opportunistic maintenance model for offshore wind turbines considering the maintenance opportunity of low wind speed shutdown events is established,and the long-term preventive opportunistic maintenance threshold is updated in a rolling manner.The final simulation results show that the model proposed in this paper can effectively reduce the cost of offshore wind turbine downtime as well as fault losses,and improve the maintenance benefits during the turbine life cycle.
