摘　　要：在分析发电设备检修与故障关系的基础上,建立了一个发电设备预知性检修时刻优化模型。该模型从设备生命周期的角度出发,综合考虑了发电单位成本、销售电价、发电机组发电量、设备检修费用、机组停运损失、延长设备检修间隔而节省的检修成本等诸因素的影响,以发电机组运行效益为目标函数,通过比较不同检修时刻点设备运行带来的收益与导致的风险损失,取使发电机组运行效益最大的检修时刻为最佳检修时刻。水泵检修时刻的优化结果证明了该模型的有效性。Based on the analysis of equipment＇s maintenance and fault, a prediction maintenance time optimization model was proposed, which brought forward the unit＇s running benefit as objective function by synthesizing the factors of generating unit cost, electricity selling price, unit generating electricity amount, maintenance expense, break clown loss and saved maintenance cost because of prolonging maintenance interval from the point of equipment ＇s life cycle. The model compared the benefit and risk from equipments＇ runnung at different maintenance time, and took the time with maximal benefit as optimization maintenance time. The nance time validates the model. example of feed water pump＇s optimization mainte
