【摘要】：风电机组运行环境恶劣,故障频发,尤其以齿轮箱的故障居多,造成风机整体维修成本偏高。针对以上问题,提出了一种基于时间延迟的状态优化维修策略,在时间延迟模型的基础上考虑振动监测信号,先结合故障数据和状态监测数据求得齿轮箱的比例危险函数和可靠度函数,再采用单位运行时间内平均维修费用最小的方法优化得到最优状态维修阈值,最后依据该阈值实施风机齿轮箱的优化状态维修。通过对某风电场仿真分析,求得了最优状态维修阈值,并制定了维修策略。仿真结果证实了该策略在避免过度维修和维修不足问题以及节约维修成本方面的有效性。
[Abstract]:The wind turbine operation environment, fault prone, especially in the gearbox fault are caused by fan overall maintenance cost is high. To solve the above problems, this paper proposes a state maintenance strategy optimization based on time delay, considering the vibration monitoring signal based on time delay model, combined with proportional hazard function and fault data state monitoring data obtained the gear box and the reliability function, then the unit operation time average minimum maintenance cost optimization method to get the optimal maintenance threshold, according to the implementation of the optimal threshold of state maintenance of wind turbine gearbox. Through the analysis of a wind farm simulation, the optimal state maintenance threshold obtained, and make the maintenance strategy. Simulation results demonstrate the effectiveness of the strategy to avoid excessive and deficient maintenance problems and save the maintenance cost.
