摘　　要：维修费用是发电成本中难以计算的部分,它的变化受制于机组可靠性的高低,而维修活动对可靠性指标之一的寿命有重要影响.首先建立基于维修的寿命等效延长模型,然后在此基础上建立发电设备维修—寿命—发电成本三者之间的量化关系,为发电成本的计算提供新的思路和方法.Maintenance cost is one of the most difficult parts to calculate in variant-cost, for it s decided by the reliability of components. As an important factor of reliability, life is largely affected by maintenance. The proportional life prolonged model based on maintenance is presented firsdy. Based on this model, the function of Mainenance--Life--Cost is deduced. Which provides a new method for power plant to calculate maintenance cost more accurately.

关 键 词：发电成本 等效寿命 维护费用 维修效果
