摘要
全寿命周期成本(life cycle cost,LCC)理论已应用于许多领域,并且取得良好的社会经济效益。电力开关设备全寿命周期成本分析常采用净现值法,但其中设备的运行维护以及故障成本通常在总成本中占相当大的比重,由于此部分费用是未来发生的费用而且设备实际运行情况是不确定的,采用盲数理论可以处理电力开关设备数据的不确定性,能够克服传统方法过于绝对化的问题。针对GIS和AIS两种开关设备备选方案进行了基于盲数理论的全寿命周期成本分析。结合资金的时间价值详细介绍了电力开关设备全寿命周期成本的费用分解结构以及计算模型。经过对这两种开关设备的LCC计算结果进行分析评价,从而确定出最优方案为GIS。该模型具备处理多种不确定性因素的能力,为电力设备选型提供了一种有效的方法。
Life cycle cost （LCC） theory has been applied to many fields, and has brought in good social and economic benefits. The net present value method is often used in LCC analysis of conventional power switchgears, but the operation and maintenance costs of equipment as well as the failure cost usually account for a large proportion in the total cost. Because this proportion of cost will be spent in future and the actual operating condition of equipment is uncertain, the blind number theory can be adopted to deal with the uncertainty of the data of the switchgear. In this paper, the life cycle costs of the GIS and AIS options are analyzed based on the blind number theory. Combined with the time value of money, the LCC decomposition of the power switchgears and the computing model are discussed in detail. The LCC calculation results of two switchgears are analyzed and evaluated to determine that the optimal solution is GIS. The model possesses the capability of effectively dealing with a variety of uncertainties, hence it can be employed for efficient selection of power equipments.
