全寿命周期成本测算是一种经济分析过程,它评估产品从购置、拥有到处置的所有成本,计入将所有未来成本折算为净现值所需的折旧(净现值NPV或者成本)。为了做好全面分析,必须对变压器全寿命期内可能发生的成本进行很好的预测。有些成本是显而易见的,很容易被计算出(如铁芯损耗),而很多其他类型成本却要么无充分依据,或者尚未为人所知,特别是有些与故障风险相关的成本。除了原料成本之外,故障所导致的计划外检修可能会产生更为严重的财务和责任后果。因此对这种后果所致风险的正确评估是任何一个变压器群组资产管理战略的基石。从不同方案的各种角度,小故障、大故障、防火和运维成本增加等,审视几种典型变压器案例。同时,按照故障风险的净现值水平对不同投资选择(维持现状,更换或者修理)的财务优点进行比较。 Life-cycle costing is an economic analysis process that assesses all costs of a product from acquisition, ownership to disposal and includes the depreciation (NPV or cost of the NPV) required to convert all future costs to their NPV. In order to do a comprehensive analysis, it is necessary to make a good prediction of the possible costs incurred during the transformer’s entire life cycle. Some of the costs are obvious and easily calculated (such as core losses), while many other types of costs are either underdeveloped or unknown, especially as costs associated with failure risk. In addition to the cost of raw materials, unplanned repairs due to malfunctions can have more serious financial and liability consequences. Therefore, the correct assessment of the risks posed by such a consequence is the cornerstone of any one transformer asset management strategy. From a variety of programs of various angles, glitches, glitches, fire and O & M costs increase, etc., look at several typical transformer case. At the same time, the financial merits of different investment options (status quo, replacement or repair) are compared against the net present value of risk of failure.
