摘　　要：寿命周期费用法 (LCC法 )实际上就是工程经济学中的年费用法在工程项目寿命周期内的应用。LCC法适用范围广 ,计算简单 ,使用方便 ,容易评估和判断 ,所以在联合循环电厂的规划设计中 ,普遍使用LCC法。为此建议 :(1)采用 2个大修周期 (12年 )作为联合循环机组的寿命周期年限 ,此年限大体上也是联合循环机组的经济服务年限和贷款偿还年限 ,这样算出的LCC比较接近实际 ;(2 )采用美元 / (kW·年 )作为年费用的计算单位 ;(3)用 1台 2 0 9FA(或2 .94 .3A)多轴机组 ,替代 2台 10 9FA(或 19.94 .3A)单轴机组 。The life cycle cost method (LCCM) is the app lication of the annual cost me thod of engineering economics in the life cycle of an engineering project. LCCM is of wide applicable scope, simple calculation, convenience for use and easy ev aluation and judgement, so it is widely used in planning and design of the combi ned circulation power plants. For this purpose the author suggests: (1) two over haul cycles (12 years) will be used as a life cycle limit of a combined circulat ion unit; this limit is also the economic service limit of the combined circulat ion unit and loan payment limit in general. So the LCC to be calculated is relat ively close to the practice; (2) US dollar/ (kW.y.) is used as the calculation u nit of the annual cost; (3) One set of 209 FA (or 2.94.3A) multi-spindle unit is used to substitute two sets of 109 FA (or 19.94.3A) single spindle unit, which is relatively reasonable in economy.
