摘要
针对风电场高昂的维修准备成本,将单台风电机组(wind turbine,WT)作为整体,风电场视为一个由多设备组成的并联系统,研究风电场的最优成组维修策略。根据排队论分析风电场中WT发生停机性故障的规律,描述对应的维修排队模型,在此基础上,通过固定故障率给出计算单台WT发生停机性故障后等待被维修的平均时间。最后,与传统维修方式对比,以节省总维修成本最大为目标建立最优成组维修模型。数值实验和灵敏度分析验证该模型的正确性和有效性,算例分析结果表明,该成组维修策略能有效降低风电场整体维修成本,实现风电场整体经济效益最优。
Aiming at the issue of high setting-up cost of maintenance in wind farms,the optimal group maintenance strategy is researched with a single wind turbine seen as a whole unit and the wind farm as a parallel system composed of multi-units.The maintenance queuing model of the wind turbine is described by analyzing the law of downtime fault of wind turbines based on queuing theory.The average waiting time of single wind turbine after suffering from a downtime fault is determined with fixed failure rate.Comparing with traditional maintenance strategy,the optimal group maintenance model is presented by maximized the saving cost of maintenance.Finally,the correctness and availability of the proposed model is verified by numerical experiment and sensitivity analysis.The results show that the group maintenance strategy can effectively reduce the overall maintenance cost of the wind farm and realize the optimal economic efficiency of wind farms.
