基于可靠度的风电机组机会维修策略

Opportunistic Maintenance Strategy for Wind Power Generators Based on Reliability

在传统预防性维修的基础上,提出基于可靠度的风电机组机会维修策略,当某一部件损坏造成系统必须停机维修时,可将其他未发生故障部件的维修时刻提前,从而减少系统停机次数。结合具体风力机实例,通过仿真分析验证了机会维修策略相较于传统预防性维修策略的经济性优势,并结合果蝇算法求出最佳机会维修阈值。

On the basis of traditional preventable maintenance,an opportunistic maintenance strategy for wind power generators based on reliability is proposed,which means that when damage of some component causes necessary shut-down and maintenance,it is able to bring forward maintenance time of other components without failures,so as to reduce shut-down times.It is proved by specific wind turbine examples and simulating analysis that this opportunistic maintenance strategy has better economy advantages compared with traditional preventable maintenance strategy.Optimal opportunistic maintenance threshold could be determined by using fruit fly optimization algorithm.
