摘　　要：风场的运维成本约占其收入的三分之一之多,风电机组的最优维修问题一直是风电系统降低运维成本的主要途径.针对同一风场多台风力机组成的系统,制定基于状态检测的视情机会维修策略,提出基于退化状态空间划分的多设备系统状态维修决策建模方法,在此基础上建立维修成本最小的解析模型,以决策风力机最优的状态检测周期和维修阈值.实验结果表明,基于状态监测的风力机视情维修机会方案可以很好地节约系统运维成本.The operation and maintenance cost of wind farms accounts for about 1/3 of its revenue. The optimal maintenance of wind turbines is always the main way to reduce operation and maintenance cost of wind farms. Focusing on a system composed of multiple identical wind turbines, this paper presents a condition-based opportunity maintenance strategy for it. A deterioration state space partition method is proposed to analyze and model the opportunity maintenance strategy for the multi-unit system. Then, an analytic model is established based on the presented modeling method to determine the optimal inspection period of the system, and opportunistic and preventive maintenance thresholds of each unit jointly for minimizing the long-term cost rate. The experimental result verifies the performance of the modeling method. It also shows that the joint optimal maintenance decision can achieve significant performance for the wind turbine.
