【摘要】 单纯依据设备投资费用进行设备选型有一定的局限性。基于设备全寿命周期成本(LCC)原理,结合资金的时间价值,介绍等年值的概念,提出电力设备全寿命周期成本的费用构成和计算模型。结合电力设备实际,给出了在LCC分析中,计及可靠性的设备投资、运行维修、停电损失等费用的等年值电力设备LCC的计算模型。通过实例进行的电力设备LCC计算分析,真实地反映了工程中现金流水平,证实了模型的正确性和工程实用性。更多还原

【Abstract】 It is limited to select equipment solely according to the investment cost.Cost analysis of each part in Life Cycle Cost(LCC) and its calculation model are presented using the LCC theory,the cost analysis approach considering the investment time and equivalent annual value.Taking electrical equipment into account the LCC model for a power equipment of equivalent annual value is presented based on investment cost,maintenance cost,outage cost.Results of case studies show that the proposed LCC model can be used to optimize the project schemes and improve the investment efficiency,and it is correct and practical.更多还原
