Abstract

The availability was low and the maintenance cost was expensive. In order to solve the problem, a new dynamical maintenance strategy applied to the component of wind turbine was presented, which was called condition based opportunistic maintenance strategy. In the strategy, Weibull proportional hazards model was used to describe the degradation of component. The paper used the monitoring information to defined the condition indicator which could characterize the condition of component. When and how a component should be maintained could be confirmed by comparing the value of condition indicator with the values of threshold function.The threshold function included condition maintenance threshold function and opportunistic maintenance threshold function which could be determined by minimizing the long-run expected cost rate. Finally, the practical valuableness and effectiveness of the presented strategy was verified by the the simulation analysis from economy and availability based on historical faults data and monitoring information.
