考虑不完全维修的风电机组预防性机会维修策略
Preventive opportunistic maintenance strategy of wind turbines considering imperfect maintenance
摘要
Abstract
Aiming at the problems of single and costly maintenance of wind turbine,a preventive opportunistic maintenance strategy of wind turbines considering imperfect maintenance is proposed. Firstly,Weibull distribution is used to model the reliability of wind turbine,the reliability of imperfect maintenance was determined according to the preventive maintenance reliability and the opportunity maintenance reliability,two maintenance methods of imperfect repair and opportunity replace was taken aiming at the key components which are in the range of opportunity maintenance;The imperfect maintenance method was modeled by decreasing age factor and failure rate increasing factor,and then the maintenance plan was determined; Then the maintenance cost model of wind turbine is established,to the lowest cost target, the imperfect maintenance reliability is optimized by cubic spline interpolation. Finally,simulations are carried out with the specific case of wind turbines maintenance,the results show the strategy can improve the coordination of component maintenance and reduce the maintenance cost,which verifies the effectiveness of the proposed strategy.关键词
