摘要
全寿命周期成本(LCC)法在工程经济学中就是年费用法在工程项目寿命周期内的应用。因此,在燃气轮机联合循环电厂的标准设计和规划设计中,可充分使用LCC分析法。就燃气轮机联合循环电厂在标准设计和规划设计阶段的投资成本、燃料成本、运行和检修成本进行了概述,并对供货方和采购方如何优化和降低燃气轮机联合循环电厂的LCC进行了论述。还就LCC分析方法在燃气轮机联合循环电厂在设计、规划中的实际应用问题,如怎样确定合理的寿命周期作为LCC的统一计算比较年限、采用何种单位作为年费用计算单位等进行了探讨,并对各类成本在实际计算中应考虑哪些方面和如何计算进行了说明。对如何运用LCC分析计算中的各项成本/费用,以分析比较燃气轮机联合循环电厂的具体问题做了细致的介绍。在对燃气轮机联合循环电厂进行LCC计算中,建议采用2个大修周期(12年)作为LCC的统一计算比较年限,并采用美元/(kW·a)作为年费用的计算单位,以使计算结果更接近实际情况。
The condition of the investment cost,fuel cost,operation cost and maintenance cost of the gas turbine combined cycle plant during the standard design and planning stage were summerized first.At the same time the measures that can be adopted by the supplier or buyer to optimize or reduce the LCC of the gas turbine combined cycle plant were discussed also.Moreover several problems that may occur during the practical application of the LCC to the design and planning of the gas turbine combined cycle plant including for example the problem of how to determine the life cycle period or in other words a fixed number of years to be used for the unified calculation and comparison of LCC and what kind of unit system should be used in the calculation of annual costs were studied.The problems that may arise during the practical calculation of the various kinds of costs and also the methods of calculation were illustrated.The problem as to how to apply the various kinds of costs or expenses calculated in LCC analysis to the analysis and comparison of the concrete problems existing in the gas turbine combined cycle plants were recommended in detail.It was suggested that two overhaul periods (12 years in total) can be used as the life cycle or in other words a fixed number of years according to which the unified calculation and comparison of LCC can be carried out and /kW·a can be used as the unit of calculation of the annual costs in order that the calculation results can conform to the real practical conditions as close as possible.
